Abstract
This invention focuses on the specialized catalyst and/or additive for lower FCCU gasoline and diesel blendstock component sulfur content. This invention utilizes a specified ratio of the transition metal oxides of cobalt and molybdenum to accomplish gasoline and diesel blendstock sulfur reduction. This is accomplished by minimizing sulfur compound formation in the FCCU riser. The cobalt and molybdenum oxides in the presence of HS from cracked organic sulfur compounds are converted to metal sulfides. A portion of the overall sulfur reduction in the gasoline and diesel blendstock occurs emitted NOalso is reduced.
