Development Of Composite Catalyst And Its Catalytic Performance In Fcc Cracking

This study presents development of composite catalyst and its catalytic performance in fluid catalytic cracking (FCC). FCC composite catalyst was formulated using as-synthesized zeolite Y and ZSM-5 anchored on support matrix made of activated alumina, metakaolin and silica sol. The catalyst was characterized using Brunauer-Emmett-Teller (BET) texture analysis, scanning electron microscopy (SEM) and Differential/thermogravimetric (DTG/TG) analysis. The BET analysis showed that the zeolite Y, ZSM-5 and FCC catalysts formulated were microporous. Incorporation of ZSM-5 reduced the specific surface area and pore volume of the catalyst by 28 and 30% respectively. DTG/TG analysis of both the zeolite Y and ZSM-5 catalysts showed that they were thermally stable. Catalytic cracking of n-hexadecane yielded 40.7%, 59.5% and 60.0% gasoline at 400, 500 and 500ËšC respectively. The corresponding gasoline selectivity were 76.5%, 81.3% and 67.5% respectively.
