Catalytic Gas Desulfurization and its Development Trend

Sulfur content restrictions of gasoline for cars were becoming more and stricter in China and abroad,and the key was to use effective technical means to reduce the sulfur content in FCC gasoline.According to the characteristic of gasoline containing sulfur compounds,a series of domestic and international desulfurization technology features and evelopment status for FCC gasoline was reviewed.Considering the status of the domestic refined gasoline,a new FCC gasoline desulfurization technology with low loss of octane number,high liquid yield and low sulfur was proposed.
