PRODUCTION OF BIOFUEL VIA CATALYTICCRACKING OF PALM OIIL USING ZEOLITECATALYSTS

摘要

Y-type zeolite is one of the most common crackingcatalysts used in the fluidized catalytic cracking (FCC)process in petroleum refineries. Motivated by gasolineregulations, researchers have been working towardimprovement on the FCC processes to meet specificationsof the octane number, vapor pressure, and content of sulfur,olefins, and aromatics. Several types of catalysts havealready been developed that are able to give higher yields ofhigh-octane gasoline. Utilization of different additives hasbeen found to affect significant change in liquidhydrocarbon composition and its distribution.
