Influence of Morphology of Zeolite Catalysts on the Main Indicators of the Isobutane Alkylation Reaction with Butylenes

Abstract

The influence of the morphology of cation-exchanged zeolite catalysts synthesized from domestic NaX zeolites on the main indicators of the alkylation reaction of isobutane with butylenes has been studied. It has been found that the catalyst preparation conditions have no substantial effect on the catalyst surface structure. The optimum indicators of the alkylation reaction (98–100 wt % conversion of butylenes, of the alkylate yield close to the theoretical yield of 99–100 wt %, TMP selectivity maintained at a level of 72 wt %, and C_8-others not exceeding 1.5 wt %) are achieved at the catalyst particle size in two ranges, below 0.8 and/or above 3.5 μm.
