Production of nanoscale zeolite composite catalysts from liquefied petroleum gases

Abstract

Nanoscale zeolitic composite catalysts have been developed by changing the methods of producing liquefied
petroleum gases (LPG) into highly selective aromatic hydrocarbons by changing the size and modules of zeolites and choosing
different methods for introducing the promoter. A new zeolite - an active and complex nanocatalyst was obtained using a singlestage technology for converting liquefied petroleum gases into an aromatic hydrocarbon concentrate that used the impurity
promoter. The most convenient catalyst is a catalyst containing 0.5% Zn. The maximum yield of aromatic hydrocarbons was
24.2% at 650 ◦ C and at a flow rate of 600 h-1. The targetted reaction is well coordinated with dehydrogenic and acidic
properties. It is possible to increase the efficiency of catalytic zeolites by modifying hydrocarbons with various elements. Thus,
zeolite catalysts play a crucial role in the aromatization of low molecular weight hydrides.
