摘要

Increasing gasoline production in FCC unit can improve the utilization efficiency of petroleum resources and gain economic benefit. This paper discusses the technical principles for increasing FCC gasoline yield from the aspects of feedstock properties, operating conditions, LCO (light cycle oil) recycling, catalyst selection and reactor type, and illustrates the industrial application examples for maximizing gasoline production. The technical measures, such as optimizing the feedstock, properly increasing the catalyst activity and reaction temperature, recycling LCO or hydrotreated LCO, applying high gasoline yield catalyst, and adopting the two-zone riser reactor, are proposed to enhance the gasoline yield.
