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. The above circumstances forced manufacturers to reduce the production of aluminum-platinum catalyst AP-56. The most productive among the units of fine cleaning plant, which includes 3 similar compartments with a capacity of up to 400 Nm3/h for raw materials, is considered. To confirm of the selected catalysts on existing equipment and for implementation, the technological calculations of the catalytic purification unit were made, and the main indicators of the process were determined.
