METHOD OF PREPARING CATALYST FOR AROMATISING LIGHT PARAFFINS

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a method of preparing a catalyst for aromatising light paraffins, based on mixing microporous material with a pentasil-type zeolite structure with pore size of not less than 5E and zinc-containing aluminium oxide. The zinc-containing aluminium oxide is obtained using aluminium hydroxide obtained by hydrolysis of aluminium isopropoxide with 0.5% aqueous isopropanol solution of methanoic acid with molar ratio aluminium isopropoxide:water:isopropanol of 1:(3-10):(10-20) and hydrolysis temperature of 30-40°C, characterised by average diameter of transport pores of 55-65 nm.EFFECT: method enables to obtain catalysts, the use of which increases the output of aromatic compounds.1 tbl, 9 ex
