CATALYST CONTAINING PRECIOUS METAL ON CARRIER FOR ISOMERIZATION OF ALKYLAROMATIC COMPOUNDS (VERSIONS) AND METHOD OF PREPARATION THEREOF

FIELD: isomerization catalysts. SUBSTANCE: catalyst consisting of zeolite- and alumina-containing carrier and precious metal-containing active component is distinguished by that it is composed of, wt %: platinum 0.1-0.4, MOR structure zeolite 10-60, ZSM-5-zeolite up to 15, and alumina 40-80. Method...

Zusammenfassung:	FIELD: isomerization catalysts. SUBSTANCE: catalyst consisting of zeolite- and alumina-containing carrier and precious metal-containing active component is distinguished by that it is composed of, wt %: platinum 0.1-0.4, MOR structure zeolite 10-60, ZSM-5-zeolite up to 15, and alumina 40-80. Method of preparing these catalysts are also described. Approximately equilibrium mixture of para-, metha- and ortho-alkylaromatic compounds is obtained on proposed catalysts. EFFECT: increased isomerization conversion of C8-aromatics and conversion of ethylbenzene into xylene. 13 cl, 11 tbl, 7 ex
