The Impact of Salt Content in Heavy Crude on The Zeolite Catalyst Performance for Olefin Production

Abstract
One of the recent advancement in the downstream industry is the utilization of heavy crude in a more economical way, one of the major utilization processes is the cracking of heavy feedstocks into lighter fractions, which can be used as a feedstock for subsequent processes such as hydrocracking, fluid catalytic cracking, and petrochemical applications.The objective of this work is to compare the performance of different aluminium oxide based on zeolite catalysts for heavycrudecracking with different salt content.The feedstock used for this study is heavy crude oil from Kuwaiti field that contains a heavy hydrocarbon fraction and a large amount of metal and salt contents. Two synthesized prototype catalysts were mixed with the crudes in a 250 ml autoclave(batch reactor) and left to react at different temperatures, the outlet gases from the reaction were analysed directly in the connected GC. The results showed a wide range of impact on catalyst performance (composition), a noticeable increase in C2 and C3 yield for the desalted crude, moreover a higher C3 produced for both catalysts at 430-450 °C this could be attributed to the large pore of the synthesized catalysts.
