FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil-processing and petrochemical industries. Heat resistant isomerization catalyst for isomerization of aromatic hydrocarbons C-8 consisting of a carrier containing, by wt. %: ordered mesoporous silicon oxide – 10.0–75.0, aluminosilicate nanotubes – 5.0–70.0, gamma-aluminium oxide – the rest up to 100, and platinum group metal applied on carrier in amount of 0.1–5.0 % by weight of the catalyst, notably, that using in the carrier ordered mesoporous silicon oxide and aluminosilicate nanotubes are a structured composite.
EFFECT: technical result is to increase conversion of ethylbenzene, to increase content of xylene of paraxylene in the mixture, to minimize losses of objective xylenes, to increase heat resistant of the catalyst.
