This lecture covers the production of gaseous and liquid fuels, focusing on important processes in oil refineries such as distillation, catalytic reforming, and fluidized catalytic cracking. It explains the physical and chemical processes involved, including hydrotreating, catalytic reforming reactions, and the mechanisms of fluidized catalytic cracking. The instructor discusses the role of catalysts in promoting desirable reactions and the challenges of coke formation. Additionally, the lecture explores alkylation as a method to produce higher octane gasoline. The presentation also touches on hydrocracking and hydrocracker reactors, emphasizing the conversion of heavy feedstock into lighter, high-octane products.
