METHOD OF PRODUCING CATALYST FOR ORTHO-CONVERSION OF PROTIUM Russian patent published in 2013 - IPC B01J37/34 B01J37/02 C01B4/00 B82B3/00 

Abstract RU 2481891 C2

FIELD: chemistry.

SUBSTANCE: invention relates to heterogeneous catalysis. The method involves obtaining rhodium or ruthenium nanoparticles when reducing ions of the corresponding metal under the action of γ-radiation of 60Co in a reverse micellar solution. The solution contains a metal salt: RhCb or RuOHCl3, bis(2-ethylhexyl)sodium sulphosuccinate (surfactant) and isooctane. The reverse micellar solutions of rhodium or ruthenium salts are prepared in molar ratio of the aqueous metal solution to the surfactant ranging from 1:1 to 10:1. Isopropanol solution and ammonia solution are then added in amount of 5-50 wt % and 10-30 wt %, respectively, and the solution is subjected to ultrasonic treatment and deaeration. The obtained metal nanoparticles are deposited on a support - SiO2.

EFFECT: invention enables to obtain a catalyst for operation in the 77-110 K temperature range.
