Gasoline precursors. Gasoline is a blend of straight run naphtha (usually light
naphtha) and products of intermediate processes. These are usually suitably boiling
range products from:
• Catalytic reforming process (see the chapter “▶ Catalytic Reforming in Petroleum Processing”)
• Fluid catalytic cracking process (see the chapter on “▶ Fluid Catalytic Cracking
(FCC) in Petroleum Refining”)
• Hydrocracking process (see the chapter on “▶ Hydrocracking in Petroleum
Processing”)
