Abstract
Additives for mixing into the base catalyst inventory of the fluid catalytic cracking (FCC) process units, so as to achieve a high selectivity of light olefins (ethylene and propylene), are described. Such additives comprise an FER zeolite and an MFI zeolite, the MFI zeolite preferably being zeolite ZSM-5. The mixture of the additive in a concentration greater than 2% w/w relative to the base catalyst of an FCC unit allows greater selectivity for light olefins, propylene and ethylene, while maintaining catalytic activity.
