FIELD: chemistry.
SUBSTANCE: present invention relates to the field of hydrocarbon conversion, more specifically to reforming of hydrocarbon raw materials in the presence of a catalyst for the production of gasoline fractions and aromatic compounds. The catalyst contains substrate, at least one noble metal M, tin, phosphorus, yttrium, and a halogen compound. The phosphorus content is from 0.4 to 0.8% by wt. relatively to the catalyst weight. The yttrium content is more than or equal to 0.01% by wt. and less than 0.5% by wt. relatively to the catalyst weight. At the same time, substrate contains silicon oxide, aluminum oxide, or aluminosilicate. The invention also relates to a method for the production of this catalyst and to its use in the reforming process.
EFFECT: provision of a catalyst with increased selectivity and stability during reforming without loss of activity.
