FIELD: chemistry.

SUBSTANCE: invention refers to noble-metal catalyst, to method for making and application thereof. There is disclosed method for making noble-metal catalyst for hydrocarbon conversion, involving the stages as follows: a) preparation of the carrier containing zeolite, chosen from zeolites with medium and large pores and acid sites, at temperature within 423 to 1173 K and optional carrier modification; b) deposition of noble metal chosen from platinum, palladium, ruthenium, rhodium, iridium and their mixtures and combinations, by gas-phase deposition including evaporation of noble metal precursor chosen from β-diketonates and metallocenes, and interaction with the carrier, and c) heat treatment in oxidising or reducing environments. There is disclosed application of noble-metal catalyst produced by the method described above, in ring opening, isomerisation, alkylation, hydrocarbon reforming, dry reforming, hydrogenation and dehydrogenation, and preferentially, in ring opening of naphthenic molecules. Additionally, there is disclosed method for making medium diesel fuel distillate by introducing raw medium distillate into the reactor wherein it reacts at temperature 283-673 K and under pressure 10-200 bar with hydrogen with added noble-metal catalyst produced as described above until ring opening of naphthenes with two or more rings completed to produce isoparaffins, n-paraffins and mononaphthenes within medium distillate.

EFFECT: production of catalyst with improved selectivity for hydrocarbon conversion.
