FCC CATALYST ADDITIVE AND A METHOD FOR ITS PREPARATION

摘要

A process for testing a zeolite based FCC catalyst and a ZSM-5 zeolite based FCC catalyst additive for simulating commercial plant yields is disclosed in, the present disclosure wherein the catalyst and the additive are subjected separately to a steaming protocol with 60 to 100% steam at a temperature in the range of 750° C to 850° C for 3 to 200 hours to obtain a catalyst and a catalyst additive deactivated under, said simulated commercial plant hydrothermal deactivation conditions. The deactivated catalyst and the deactivated catalyst additive are admixed in a pre-determined weight proportion. The obtained catalyst mixture is then used for cracking a hydrocarbon feed for a pre-determined period of time to generate cracking data. Product yields are measured from the generated cracking data at a pre-determined simulated commercial plant conversion of the hydrocarbon feed.
