Abstract: Based on the technology and operation situation of the 2.5 Mt/a FCC unit in PetroChina Sichuan Petrochemical Co.,Ltd.,technical measures for increasing the gasoline yield were analyzed in aspects of the process,raw material,catalyst,reaction extent,and gasoline distillation of the product,including processing residue hydrotreating diesel,reducing residue blending ratio,improving the quality of raw materials,controlling suitable catalytic cracking catalyst activity,using shape -selective catalysts,appropriately increasing reaction extent,injecting quench oil,raising the dry point of gasoline,reducing overlap of gasoline and diesel fractions, broadening the gasoline boiling range,and so on.
