        The catalysts of NIAP-15-12 series are used to purify process gases (N2, Ar, H2, He) from oxygen, waste gases – from O2, CO, NH3, and for deep methane oxidation.

The catalysts are used for the catalytic purification of process gases from oxygen at the temperatures of 150 ÷ 800 °С, pressures of 0,025 ÷ 30 MPa, space velocities of 500 ÷ 25000 hour-1 and with oxygen content in feed gas in two-stage purification of argon not more than 4 vol% and of nitrogen – not more than 7 vol%. The catalysts provide the residualoxygen content not more than 0.0005 vol% under the conditions mentioned above.

          Sulphur removal catalysts are used for cleaning of natural, associated and process gases from sulfur compounds: NIAP-01 family - for the hydrogenation of organic sulfur compounds to H2S, NIAP-02 family - for the absorption of sulfur from H2S by active zinc oxide with promoters.

Hydrocarbons reforming catalysts

Catalysts forprocess and off gases

The low-temperature shift catalysts are used in the second stage (LTS) of CO shift at most of the modern ammonia and hydrogen plants using natural gas and other hydrocarbons, as well as in the cyclohexanol dehydrogenation stage at caprolactam plants.

The catalysts are used to produce reducing and protective atmospheres for metal wares processing at metallurgical and machinery works.
