Abstract

The alkylation of isobutane with cis-2-butene on H-BEA, H-FAU and H-EMT catalysts was studied in a well-mixed continously operated tank reactor. All the catalysts selectively catalyzed alkylation. Catalyst stability correlated directly with the concentration of Brönsted acid sites of the catalysts. The changes in the octane isomer distribution are attributed to differences in the hydride transfer rates. With H-EMT and H-FAU, the alkylate yields suggest a significant amount of isobutane self alkylation indicating that the resulting hydrogen is strongly bound to the catalyst surface or removed from the system.
