Abstract (type = abstract)
Crude oil refining produces numerous light hydrocarbons (alkanes and alkenes). Of these, C2-C4 hydrocarbons are commercially important precursors for synthetic rubber, polymers and other chemical products. C5 hydrocarbons are unwanted by-products; they are not suitable as liquid or gaseous fuels, leading to difficulty regarding storage and handling. The present work is based on an idea to convert C5 hydrocarbons to fuels via dehydrogenation of C5 alkanes, oligomerization of C5 olefins to C10 and C15 alkenes, and further hydrogenation to fuel-grade medium molecular weight hydrocarbons. We have devised a synthesis strategy to transform the light olefins to more valuable decenes (C10 olefins), which can be used as gasoline alternatives. This transformation is termed as the oligomerization of pentene by the catalysts acid-form zeolites. Zeolites are popular catalysts for a variety of heterogeneous catalytic reactions in research as well as in the industry. The oligomerization of pentene was investigated over ZSM-5 (MFI), Beta (BEA*), Mordenite (MOR), Ferrierite (FER) and Faujasite (FAU). The primary aim is to achieve high activity and selectivity for oligomerization over cracking of pentenes and decenes. The effect of zeolite pretreatment, substrate concentration, reaction temperature on yield and selectivity of decenes was studied. FAU showed a promising high selectivity, so the Si/Al ratio of FAU samples was varied and a Si/Al ratio of 6 showed the greatest yield. Being acid-catalyzed, the products of the reaction are highly branched, implying higher octane ratings and therefore suitability for gasoline blending.
