MULTISTAGE CATALYST REACTOR FOR THE SELECTIVE OXIDATION USING PRECIOUS METAL CATALYST AND MIXED METAL OXIDE CATALYST

摘要

One embodiment of the present invention is directed to a selective oxidation catalytic reactor for selectively oxidizing carbon monoxide to carbon dioxide in a mixture containing hydrogen and carbon monoxide, wherein a noble metal catalyst is disposed at the front end of the selective oxidation catalytic reactor, And a composite metal oxide catalyst including a first metal element (M1) and a second metal element (M2) at a rear end thereof. The reaction gas is in contact with the noble metal catalyst sequentially and then with the composite metal oxide catalyst A multi-stage selective oxidation catalytic reactor using noble metal catalysts and composite metal oxide catalysts is provided.
