Abstract
The present invention pertains to the use of mesoporous ZSM-22 zeolite in a process for the cracking or conversion of a feed comprised of hydrocarbons, such as, for example, that obtained from the processing of crude petroleum, to a mixture high in propylene. Further, the present invention concerns the field of fluid catalytic cracking (FCC) processes and relates to the preparation and employment of additives based on zeolites having increased mesoporosity, such as altered ZSM-22. More particularly the present invention discloses a process for improving the production of propylene in FCC units.
