Catalyst for the oxidation of amÈnia comprising alumìnio oxide, oxide of bismuth and manganese oxide.

摘要

Invention patent: b "catalyst of the oxidation of amu00c8nia comprising alumu00ecnio oxide, oxide of bismuth and manganese oxide" d .Catalyst claimed to be used for producing nitrous oxide by oxidation of ammonia with oxygen.The invention is addressed to provide catalysts with a high activity.When the content of oxygen in the reaction mixture is near or below a stoichiometry and high selectivity with respect to the nitrous oxide and the selectivity is low with respect to the oxide.Nitrogen.The catalyst composition is as follows, mass%: manganese oxide (referred to as MnO ~ 2 ~) of 5.0 to 35.0; bismuth oxide from 4.5 to 30; aluminum oxide from 35 to 90,5; specific surface area is 5 to 80 m2 / g.
