Lately, I’ve been reading up on the
processes and procedures that go into making a bioethanol.
A very interesting
part of the procedure is the initial process, called the pretreatment. The
pretreatment is the step that begins the process of breaking down cellulosic
biomass by using a chemical solution of an acid or alkali. After using the
chemical solution on the feedstock, you wash it with water and treat it with a
number of other solutions. I haven’t done this process yet, but I am
apprehensive due to the likelihood that I will be handling a caustic
substance with little between me and it.
The pretreatment fits into my work by
kicking off the process of making bioethanol, where it dissolves the feedstock
into a substrate to be digested by enzymes and fermented by microorganisms.
There are many steps to making a bioethanol, but the process is comparable to a
recipe once written out in detail. All you need is the ingredients and equipment, and then you can rinse and repeat.
