FCC Additives

Grace Davison has been the technology leader in the FCC Additive field since the introduction of combustion promoter technology in the mid 1970s. Grace was the first company to commercialize an FCC SOx additive, as well as ZSM-5 additive technology in 1986. Grace Davison is the only supplier offering a full range of additives, including combustion promoters, octane-enhancing additives, and DESOX™ for SOx emissions reduction.

Grace Davison continues the tradition of leadership in FCC Additive technology with new product introductions targeted for gasoline sulfur reduction, NOx emissions reduction, CO combustion control without NOx formation, and selective bottoms upgrading.
