Computational modeling of thiol formation in fcc gasoline hydrodesulfurization

摘要

Recently,there has been a growing need to reduce automobile emissions,and the specifications for gasoline sulfur have grown more demanding year by year.In Japan,a gasoline sulfur regulation of 10 ppm will take effect in 2008.FCC gasoline (Catalytic Cracked Gasoline:CCG) is one of the major components of the gasoline pool,and its share of the gasoline blend has reached about 50% in Japan.Because CCG contains much more sulfur than the other gasoline components,that sulfur must be removed in order to produce sulfur-free gasoline.
