Combustion promoters are required to ensure smooth regenerator operation, control of afterburning and reduction of CO emissions.

CAT-AID, Johnson Matthey’s INTERCAT catalyst enhancement additive, is designed to overcome many of the shortcomings related to deactivation of base catalyst from metal contaminants such as vanadium, nickel, iron, calcium, sodium, and potassium.

Johnson Matthey’s INTERCAT range of NOXGETTER additives are tailored to capitalise on the inherent NOx emission gradients that exist in the regenerator.

When propylene demand is high, Johnson Matthey’s INTERCAT ZSM-5 based additives are highly selective for cracking low octane gasoline range molecules to C3 and C4 olefins with no increase in coke or C2 and lighter gases.

Johnson Matthey’s INTERCAT SOXGETTER and LO-SOX PB families of SOx reduction additives have been developed to decrease the cost of removing SOx from the FCC flue gas in full burn, partial burn and two-stage regenerators.

To achieve the reduction in gasoline sulphur, the refiner has a number of options to choose from. Most options involve trade-offs between high capital costs and gasoline yield loss.
