Abstract

One solution of the problem of deactivating zeolite-containing alkylation catalysts is to use supercritical conditions in the process where the supercritical hydrocarbon fluid that is formed removes the high-molecular-weight condensation products formed on the catalyst surface. This paper reports the results of prolonged pilot tests of catalysts based on modified polycation-decationized Y zeolites in an ultrastable form in alkylation with in-situ catalyst regeneration.
