Oxygen Removal Catalysts

The Noble Deoxo Catalyst combines oxygen with hydrogen (catalystically under reducing condition) to form water vapor and operates at temperature from –40 deg. C to approximately 600 deg. C. The gases treated may be hydrogen or any inert gas in which there is a quantity of hydrogen approximately 0.25 % v.v. minimum in excess of stoichiometric. Such inert gases can include Nitrogen, Argon, Helium and the other noble gases, Carbon Dioxide etc. The maximum recommended oxygen removal is 3 % per pass.

The removal of gaseous impurities by chemical reaction over a catalyst is normally accompanied by the release of heat i.e. it is an exothermic reaction.

Approximately 235 deg. C theoretical temperature rises for removal of 1 % v/v oxygen from Argon.

Please note that although the theoretical temperature rises will provide a good guide to the Catalyst Purifier’s exit temperature, the actual temperature will depend on the heat capacities of the other gases present and the heat losses to the temperature.

Noble Deoxo Catalyst is Tablets (3 mm x 3 mm) and Spheres (2 mm to 4 mm) size. 

Noble Copper Catalyst used to deoxidation of inert gas & other gas streams and also for simultaneous deoxidation and shift conversion duties. Such process streams such as endo gas from gas generator produced (formed by burning of LPG and other hydrocarbon and air in the ration of approximately 1: 20-25) has to be purified. A typical gas composition often found in such streams is as under –

The Noble Copper Catalyst can handle gas streams such as above for simultaneous removal of oxygen and conversion of CO & Co2. Any other gas stream containing above gases in varying proportions can also be handled on this catalyst.

Gas Streams containing only CO and Oxygen with No Hydrogen, the CO is converted to CO2 by oxidation. The operating temperature ranges between 150 deg. C to 250 deg. C and pressure of operation could be from few to several kg/cm2

Noble Copper Catalyst is available in 5 mm x 5 mm Tablets.
