The selection of catalysts that provide stability and high oxidation rate of hydrogen and methane in the reactors R 2 compartments of helium Orenburg helium plant

This article presents an overview of promising catalysts, the selection of the most effective, calculated the economic effect of the introduction of a new catalyst. The selection of catalysts providing stability of operation and high rate of oxidation of hydrogen and methane flowing in the reactor P 2 of the helium fine purification unit of helium production from helium concentrate was made. To ensure the technological process in the production of chemical, gas processing and oil refining enterprises, catalysts of different modifications and types of both domestic and imported production are used. For stable operation and high oxidation rate of hydrogen and methane flowing in the reactor P-2 of the helium fine purification unit-22 of the Orenburg helium plant, the AP-56 aluminum-platinum catalyst is used. The catalyst AP-56 participating in oxidation processes in connection with the improvement of the technological process does not meet the standards established in the technological regulations, including an increase in hydrogen concentrations, and this in turn worsens the quality of gasoline fractions, in addition, the catalyst AP-56 is promoted by chlorine, which contributes to the development of corrosion on heat exchange equipment located after the reactor...
