Crude Oil From Biomass: Evaluating KiOR

Cracking Biomass Back when I worked in a refinery, I used to spend a lot of time thinking about how biomass would behave in certain refining processes. A fluidized catalytic cracker (FCC), for instance, takes oil and subjects it to heat and a catalyst to fracture larger hydrocarbons into smaller ones that can serve as gasoline blending feedstock (among other things). Another refining unit is a delayed coker. Very heavy oil is subjected to even higher temperatures than in the cracker, and once again the hydrocarbon chains are cracked into smaller molecules useful for further processing into gasoline and diesel. Petroleum coke, similar in appearance to coal, is also produced. Given the extreme conditions of these units, either of them… Continue»
