Noncapital intensive technologies reduce FCC sulfur content – Part 1

Innovative solutions such as catalysts and membranes can be used to navigate the 'roadmap' for clean fuels agenda

Lesemann, M., Schult, C., Davison Catalysts

The fluid catalytic cracking (FCC) unit is the gasoline "workhorse," especially for North American refineries. FCC products contribute the highest sulfur content to the gasoline blending pool. Thus, lowering the sulfur content of FCC products is a high priority. Technology - existing and new - will provide crucial solutions for planning clean-fuels programs. Novel proprietary FCC catalysts and additives are being specifically designed to reduce the concentration of sulfur and olefins in the FCC gasoline.a These developments may substantially reduce the operating costs and, in some cases, allow refiners to avoid capital expenditure for gasoline post-treatment. In cases where post-treatm
