Abstract

This study presents the Run Octane Number (RON) analysis of gasoline obtained from catalytic cracking of n-hexadecane using composite fluid catalytic cracking (FCC) catalyst. Composite FCC catalyst was formulated using as-synthesized zeolite Y and ZSM-5 anchored on support matrix made of activated alumina, metakaolin and silica sol. The as-prepared catalyst was characterized using X-ray diffraction, the composite catalyst performance at 400, 500 and 550 ºC were 53.07, 73.17 and 88.85 %, respectively. The gasoline produced at 400 ºC had paraffinic content of 53 %, olefin and aromatic content of 47 %. The gasoline produced at 500 ºC had paraffinic content of 39 % olefin and aromatic content of 43 % while the gasoline produced at 550 ºC had paraffinic content of 36 % olefin and aromatic content of 44 %. The gasoline obtained at 400 ºC had the least RON value of 51.47 % whereas those obtained at 500 and 550 ºC had RON values of 85.39 and 87.38 %, respectively. This study has shown that the optimum operating temperature was 500 ºC and incorporation of ZSM-5 in FCC catalyst formulation improved the catalyst performance
