 What we're looking at today is a fluidized bed gasifier. Essentially what goes on inside of there is you'll have more irregular size material and you'll be mixing it with sand and the gases will make it almost act like a fluid as it's forming. And a little bit will show you a small fluidized sand bath so that you can see how it might work on the inside. We'll also be talking about pyrolysis, which is a thermal reaction similar to gasification but it's at a little lower temperature and it has no oxygen in it at all and so we'll learn about that during the week. We have fast, slow, and ultra-fast types of pyrolysis. We also use different types of units and the primary goal of a pyrolysis unit is to produce liquids rather than gases. We'll also be talking about biomass pretreatment. The biomass pretreatment, the method that we're trying, it's a method that we're using to try to separate out the cellulose from all the other materials that are in a plant and so that will also be discussed in our lesson. We'll also have a carbohydrate tutorial so you can see the chemical structures of the carbohydrates as well as where some of these fit into the plant.
