Alkylation of isobutane by 1-butene over H-beta zeolite in CSTR (Part 3) effect of property of h-beta zeolite

H-beta (^*BEA) zeolite catalyst has high activity/stability for the alkylation of isobutane with 1-butene in a CSTR, based on the catalytic nature of H-^*BEA. Various preparation methods for H- ^*BEA were investigated to optimize the catalytic activity for alkylation, including Si/Al ratio, H⁺/Na⁺ ion exchange rate, and grain size of zeolite. The relationship between Brønsted acid amount and butene consumption over the catalyst lifetime showed a positive correlation. H-^*BEA zeolite with larger grain size and prepared with longer crystallization time achieved higher alkylate yield based on the higher hydride transfer activity.
