Bio-Char, Bio-Oil & Syngas from Wood Pyrolysis

Appropriate Technology graduate students at Appalachian State University in Boone, NC demonstrate the pyrolysis of biomass in an airless system. Using fractional distillation, three distinct, value-added products are produced: bio-char, bio-crude, and syngas.

@ stndnthdrk: I believe we fabricated the cyclone filter using steel pipe & sheet metal, although this was before my time. All the cyclone filter does is allow the air to slow down, and particulate drops out. The inlet is tangent to the chamber, so the air swirls around. @froonbazhooley We intend to run a generator on the syngas to produce electricity and heat, after we've condensed out the liquid hydrocarbons and the water. The jury is still out on what we'll do with the bio-crude/bio-oil.

The ch4 ho and h2 can be run into a ficsher tropsch reactor with a cobalt based catalyst and you can grow hydrocarbon chains favoring diesel fuel. Basically what the earth did in fast forward produces everything from natural gas to propane to gasoline to kerosene to diesel to naptha to waxes distille and you have sulfer free fuels that are 40% cleaner than fossil fuels all from wood

where did you get the cyclone filter?

I have seen the American ARMY using polystyrene, as a diesel additive? It blends readily at5% when the amount is increased: It leaves more sooty residue, as the molecules are bigger.

The answer about making diesel by this method is No.

This liquid consist acetic acid and methanol. If get methanol from this liquid by netralizing acetic acid with calcium hydroxide. Then you can mix methanol with vegetable oil and caustic soda under the temperature, and then separate glycerol from biodiesel. You will get what you want - free diesel. Before this biodisel also will need to wash it with water from the rest oof caustic soda.

Now I am learning this, ant trying to make practice.

Great Video All! I am working at UNBC in Canada in this and we are looking at putting in a 2 MW biochar-energy system. best of luck!

Great video and it answers some of my questions. Thank you.

[AdielShnior]

great! how do u seperate the oil in the first filter? where can i find plans for this?

[SCENARIOBABY]

wonderful vid! keep em coming!

The first stage bio-crude produced has properties very similar to diesel. However, we haven't explored it yet as a possible diesel alternative. It would likely need some processing, I don't think you could put it straight into an engine; it might work right away for home heating purposes, though.
