Summary: | Additives for mixing with the catalyst inventory in process units for fluid catalytic cracking (FCC) for maximizing the production of LPG and light olefins are described. Said additives comprise a matrix that incorporates a zeolite of type MFI, preferably zeolite ZSM-5, a zeolite of type Y, and a source of phosphorus, in a single particle. Mixing of the additive in proportions from 1.0 to 40 wt.% with the equilibrium catalyst of an FCC unit maximizes the production of LPG and light olefins, chiefly propylene. |
