Abstract
An improved process for alkylation of isoparaffins with olefins to yield a product which includes a high proportion of highly branched alkylates for blending into gasolines. The improved process comprises contacting the isoparaffins and olefins with a catalyst comprising ZSM-20, preferably a HZSM-20 zeolite or a rare-earth cation exchanged ZSM-20 zeolite.
Claims15
A process for effecting alkylation of isoparaffins which comprises contacting an isoparaffin containing from 4 to 7 carbon atoms with an olefin containing from 2 to 7 carbon atoms at a temperature of from about room temperature to about 400.degree. F., a pressure sufficient to maintain at least the isoparaffin or olefin or both in the liquid phase and a molar ratio of isoparaffin to olefin of from about 3:1 to about 20:1 in the presence of a catalyst comprising a synthetic crystalline zeolite exhibiting an X-ray powder diffraction pattern which shows the significant lines set forth in Table 1.
