Making Biodiesel From Waste Vegetable Oil | Utah Biodiesel Supply

[SteelerSVK]

Hello, i have one question.... Can i use ethanol instead methanol?

[UtahBiodiesel]

@SteelerSVK Yes. But it's a royal pain in the rear. You have to use quite a bit more, and washing it can be really, really tricky, but it is doable.

[boliviangirls]

How can I make the titration solution with sodium hydroxide instead of potassium hydroxide???... actually, how I can make the whole thing using sodium hydroxide, because It's all I could get in Va.

I bought the DELUXE TITRATION KIT from your web site, and that comes with 10 grams of potassium hydroxide.

Do you guys have a book I can buy for this kind of questions???.

[UtahBiodiesel]

@boliviangirls Using the Deluxe Titration Kit, use the scale that came with it and measure out 1 gram of your Sodium Hydroxide. Put it in the titration solution bottle and add the distilled water. Then you'll be set to titrate with sodium hydroxide.

The formula for making bio with Sodium Hydroxide is in our titration kit instructions as well as on our website utahbio dot com (left-hand side under Biodiesel Basics: How To Titrate)

[UtahBiodiesel]

@boliviangirls We don't offer a book, but we do have a really great (2) DVD set available that will walk you through making Biodiesel from scratch. It's right on the front page of the website utahbio dot com

[UtahBiodiesel]

@boliviangirls Use 1 gram Sodium Hydroxide, 1 liter distilled water & you have sodium based titration solution. Yes. You can use sodium for the whole process. Adjust your base down to 5.5 though. Divide it by the purity though. 5.5/.95 = 5.8.

We don't have a book, but we do have a great DVD. It's our Biolyles Biodiesel Workshop DVD & is available on our website. utahbio dot com

[boliviangirls]

@UtahBiodiesel Thank you very much, now, I have a question, if this small batch you mix it for five minutes, for how long should I mix a larger batch???, lets say 10 litters.

[UtahBiodiesel]

@boliviangirls I'd mix it for at least 20-30 minutes.

[lwoodward53]

What a great set of videos! Who can we contact to request permission to use these for educational purposes?

[UtahBiodiesel]

@lwoodward53 contact us at info at utahbio dot com about it.

[soundmasterj18]

what is the 7 in 3+7 for?

[UtahBiodiesel]

@soundmasterj18 7 represents the amount of catalyst required to react new oil into Biodiesel. 3 represents the extra catalyst needed to neutralize the free fatty acids in the oil and still have enough to make Biodiesel. Watch our "Why we titrate" video for a great explanation as well.

[librahim2]

i have a presentation project on Biodiesel from waste cooking oils can somebody plz help me

[UtahBiodiesel]

@librahim2 Visit the tutorial section on our website at Utah Biodiesel Supply (google it--I can't post the URL in a comment). We have tons of information that you could use in your presentation.

-Graydon

[librahim2]

@UtahBiodiesel thank you

[mantiss1234]

hi there just wondering why is it 10grams in the catalyst needed 3+7, it is always 10 grams

[UtahBiodiesel]

@mantiss1234 It depends on what the titration is. A higher titrating oil will cause you to need to use more grams per liter.

[HussamStands]

This is very clear biodiesel. I don't think that getting such clear fuel is easy at all. This is actually as clear as the gasoline from the Shell lol.

[poooky321]

Do larger scale videos.

[NeonGenesisPlatinum]

was pissing myself at the fact you know all this but couldn't add 3 + 7 LOL.

Very good video though, thanks man.

[graydonblair]

@NeonGenesisPlatinum Yeah....the sun was really bright that day & I didn't see the numbers I'd written down. Didn't realize I'd screwed it up until I got into editing. By then it was too late. But yep, still human.

[NeonGenesisPlatinum]

@graydonblair That's it!!! I just thought it was funny, don't worry i'm not having a go!

[dieselperformance17]

I got a titration kit to get me started in learning and Ive been trying it over and over and I think I may have it , it took 5ml of titration solution to make a sorta pink color but nothing as clear as your pink, what can I be doing wrong , and I use the exact same ingredients as you

[UtahBiodiesel]

@dieselperformance17 As long as it's a pink color, you're good. The oil will discolor the pink a bit, so it doesn't have to be as pink as mine was. Mine was also in the bright sunlight too so it exaggerated the color change.

[adamslurch71]

Why waste so much tme and extra money on teh biodiesel when all you need to do is strain the WVO and tada you have a viable fuel for a diesel car? I have been running strained WVO for just over 3 years with Zero problems, more power ( about 5-10%) and identical MPG as straight diesel yet I'm getting my oil for free, spent about $250 on barrels and filters 3 years ago and only strain the crap out of it down to 10 Microns. Its free to pick up and cost nothing to produce usable fuel.

[Unclesamslair]

Don't you need to clean the waste vegetable oil first?

[UtahBiodiesel]

@Unclesamslair Yes. You need to filter the oil (we go down to 400 microns) and also remove the water.

[Unclesamslair]

@UtahBiodiesel thx 4 the quick response

[Fuckallbi]

way too complicated

[freewolf124]

What molarity of the KOH do you need to do the titration?

[graydonblair]

@freewolf124 Not sure on molarity, but you want to make sure it's at least 90% pure. Industrial grate usually is.

[spc6grl]

Question: When you wash the biodiesel, how exactly do you separate it from the water? With hoses and pumps, or is it a more thorough process?

[graydonblair]

@spc6grl It's usually done in settling tanks. ie. the water sinks below the biodiesel, settles out and is removed. Once the majority of the water is removed, the biodiesel can be circulated with heat applied to evaporate off the remaining water.

[spc6grl]

@graydonblair Thank you for your answer. Another question (sorry, just curious): I've heard that you can also use Lye in the process instead of KOH. What exactly is the difference?

[derekne]

Ps 1 week ago I didnt know a thing about bio. However I then found you and your videos. Ive watched them all a few times each !!!

The amount ive learned in such a small space of time is a credit to you sir. I thank you for your time and effort for showing us all in great detail how to make bio diesel.

From us all thank you very much!!! Regards Derek

[graydonblair]

@derekne Glad you've enjoyed them! Stop by the site at utahbio com as well for even more great tutorials. biodieselreview com is also great.

[derekne]

Hello im sorry if this seems like a strange question but how much water is needed to wash per litre of bio? Is there a ratio? Also can it just be hose piped into a tank of bio?

[UtahBiodiesel]

@derekne That's a great question. It's about a 1 to 1 ratio. Ie. if you make 1 liter of Bio, it'll take about 1 liter of water to wash it. For mini batches, you do 3 water washes (split the 1 liter of water into 3), and just pour it into the bottle and gently slosh it around. For large batches, yes, you can run a hose into the tank with a mister on the end of it.

[derekne]

@UtahBiodiesel

Thank you for your reply m8.

So if I had say 200 litres of bio in a large tank are you saying it will require around 200 litres of water? That sure is a lot of water. Im guessing trying to get all that water away is going to be a night mare. Even with it in the sun and with various aquarium bubblers and useing the recirculation method. Any thoughts on my reply sir?

[graydonblair]

@derekne Yep! 200 liters of water. Yep. It can definitely be a nightmare at times. Sun w/ aquarium bubblers do great. Recirculation to dry oil is the best though.

[VirkDS]

Ok i understand that there are risks involved but i watched one video where the guy was making it sound like this was a bad idea to attempt at all to make your own bio diesel

[UtahBiodiesel]

@VirkDS As long as you take the proper precautions, Biodiesel can be made safely. It also depends on your situation as to how much realistically can be made safely.

[changomonster]

I have made many batches of bio-diesel and i would like to know if you know a practical way to test rather or not i have real "bio-diesel" . Thank you

[UtahBiodiesel]

@changomonster Yes. It's called the 3/27 test.

Look through our videos for the 3/27 Biodiesel conversion Test. It's one of the oldest ones we have on here but it'll walk you through how to do it. Very simple test.

[changomonster]

@UtahBiodiesel I have tried the methanol test many times with each batch and after each wash making sure impurity are to a minimum , still the 3/27 test is not a way to test rather or not it contains the same property's like diesel. Please help and thank you for your quick reply.

[UtahBiodiesel]

@changomonster what "Biodiesel Property's" are you looking for?

The 3/27 will let you know if you have a good reaction. The soap test (see our website) will let you know if you got all the soap out. The titration test will tell you how much to react with it.

However, if you need to test it to see if it meets the ASTM standard, you'll have to send it off to a lab. I like Gorge Analytical and Bentley Biofuels for ASTM testing.

[cqr80]

Where can you buy the phenolphthalene?

[UtahBiodiesel]

@cqr80 It's available on our website at Utah Biodiesel Supply in the chemicals section.

We carry it in 15 mL or 130 mL varieties and in multi packs. (see the video description for a link to our site)

[cloudiow]

HEy i got a question, i got science project working on to make my own bio diesel.

i go a question. Is there a differnce between sun flower oil, vegtable oil or soja oil?

and which of those you preffer thanks!

[UtahBiodiesel]

@cloudiow Yes. They are different oils. I prefer sun flower oil as it has lower gel points.

Visit Biodiesel Pictures (can't give a URL in comments, just hit Google & search for it), then go to the Biodiesel batches section. I did a study on different oils and their gel points that was really telling on the different gel points of different oils.

[cloudiow]

@UtahBiodiesel Thanks alot utah bio-diesel :)

but i got some questions, for my big project :) regarding your method.

1. Why did you use 2-propanol for the tritation

2. Does it matter if you use ethanol or methanol for the mixture with NaOH.

3. Why/ what did you add for the pH ? that part i didnt get i mean will it mix better when it has a certain Ph value?

could you plesase anwswer these? :D

it would help me so much! on my project for a good grade ^^

[UtahBiodiesel]

@cloudiow

1) It's the standard alcohol to use to do titrations with among home brewers. You can use Tolene with Isopropyl, but Isopropyl Alcohol works great

2) Yes. Methanol works much better. Ethanol will work, but it has to be absolutely dry to do so (we're talking 99.9% pure). And even then it's a royal pain in the butt to wash Biodiesel made from Ethanol.

3) Not sure on your pH value question. All I do is add enough KOH solution to neutralize the acids and then measure how much it took.

[budupayang]

@UtahBiodiesel thanks for ur video.but i why did u add the volume of KOH solution with 7?

how did u determine the KOH basic?tq~

[budupayang]

@UtahBiodiesel @UtahBiodiesel thanks for ur video.but i why did u add the volume of KOH solution with 7?

how did u determine the KOH basic?tq~

[UtahBiodiesel]

@budupayang When oil is new, it still requires 7 grams of KOH per liter of oil to react the oil into Biodiesel. We call this the "base" amount. If you have a chance, watch our latest titration videos as we explain with a great analogy where the 7.0 comes from and why it's important.

Thanks for watching!

[cgm0826]

im kind of pondering on the idea of converting a diesel truck into biodeisel.after watching this vid im wondering if even after buying all this equip if its a cheaper alternative to regular gas? im a noob to this subject.

[joshua11360]

thanx this really will help me on my science project wish me luck!!! ; ]

[UtahBiodiesel]

@joshua11360 Best of luck!

[euheide]

Thanks for the video! :)

[garyconway86]

i tried to make bio from wvo i done my titrations 2.5g potassium hydroxide + 7g base =9.5g. i cannot get my bio to be as clear as yours i washed it out several times it runs on my vehicle really good but how can i get my bio more clear great video clips watched them all cheers graydon

[UtahBiodiesel]

@garyconway86

Sounds like you're oil isn't quite dry yet. Take a sample of the fuel and let it air dry in a mason jar for a couple of days & see if it clears up. If it doesn't, do a soap test. Feel free to email me (contact info on my website--see description) and I'd be happy to help you through it.

[wellemeyerp]

you also have to remember that depending on the oils you use it may come out different. quality biodiesel doesnt always look pretty

@garyconway86

[rags91192]

what formula would you use from making the 1 liter test batch to a 40 gallon ful batch

[graydonblair]

@rags91192 Recipe for 1 liter batch 1 liter oil 20 mL Methanol 12 grams KOH Recipe for 40 gal 40 gal oil 8 gal methanol 1821 grams KOH This assumes a titration of 5 using KOH based solution. See link in description for more information.

[anko1945]

thanx!! this vid really help my final year project! luv it!

[duckman714]

How do you know when the finished product is dry?

[UtahBiodiesel]

Place a little sample of the Biodiesel in a hot pan or use a water test kit to test how dry it is. Check out our video on the water test kit to see how it works.

[HEAVYSNIPE123]

@UtahBiodiesel whats the song called?

[UtahBiodiesel]

It's called Acoustic Sunrise and is a stock audio clip in iMovie 08/09. I love it!

[jessesuit]

is it absolutley nessecary to use distilled water when washing on a large scale(1,000 gal+?) also do you think its cheaper to buy it or distill it yourself?

[UtahBiodiesel]

Nope. The distilled water is actually just for the titration solution. You can wash it with standard water.

[graydonblair]

For NaOH, you use a base figure of 5.5 in the titration. You also need to titrate with NaOH based titration solution (1 gram NaOH + 1 liter of water). Everything else is the same though.

[graydonblair]

Thanks for watching. Glad to hear you enjoyed it.

[jessesuit]

i want to use NaOH instead of KOH. do the same ratios apply for all reactions?

[greenberet88x]

Excellent demonstration, very easy to understand and implement ! Good Job!!
