COPPER- AND MANGANESE-CONTAINING CATALYSTS BASED ON NON-NOBLE METALS FOR OXIDATION OF CARBON MONOXIDE AND VOLATILE ORGANIC COMPOUNDS Russian patent published in 2014 - IPC B01J23/889 B01J35/04 B01D53/00 B01J23/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods (versions) of oxidation of carbon monoxide (CO) and volatile organic compounds (VOC), as well as to a catalytic composition for the said processes. The methods include a stage of bringing tail gases of a method of obtaining purified terephthalic acid, containing water vapours and the said CO and VOC, in contact with a catalyst composition, containing a promoter based on a non-noble metal and a catalyst based on a non-noble metal, applied on an oxide carrier, which includes one or several materials, selected from aluminium oxide, silicon dioxide, zirconium dioxide, cerium dioxide and titanium dioxide. The said catalyst composition in fact does not contain platinum group metals, and the said VOC include one or several compounds, selected from methylacetate, methane, methylbromide, benzene, methanol, methylethylketone, butane and butene. The catalyst based on a non-noble metal is selected from the group, consisting of copper (Cu), iron (Fe), cobalt (Co), nickel (Ni) and chrome (Cr), and at least one promoter of the catalyst based on a non-noble metal is selected from the group, consisting of neodymium (Nd), barium (ba), cerium (Ce), lanthanum (La), praseodymium (Pr), magnesium (Mg), calcium (Ca), manganese (Mn), zinc (Zn), niobium (Nb), zirconium (Zr), molybdenum (Mo), tin (Sn), tantalum (Ta) and strontium (Sr).

EFFECT: elaboration of the alternative catalysts, demonstrating high activity and long-lasting quality.
