Title:
一酸化炭素の選択的酸化のための触媒及びその製造
Document Type and Number:
Japanese Patent JP4181774
Kind Code:
B2
Abstract:
The invention pertains to the preparation and use of catalytic materials and catalyst members for the selective oxidation of carbon monoxide in a gas stream that contains hydrogen. One such catalyst member may be produced by depositing by electric arc spraying a metal feedstock onto a metal substrate to provide a metal anchor layer on the substrate, and depositing a catalytic material comprising platinum and iron dispersed on a refractory inorganic oxide support material onto the metal substrate. The catalytic material may optionally be produced by wetting the support material, especially a particulate support material, with a platinum group metal solution and iron solution and drying and calcining the wetted support material in air at a temperature in the range of from 200° C. to 300° C., preferably using a solution containing bivalent platinum ion species. The catalyst member may be used by flowing the gas stream therethrough at a temperature at about 90° C. with a O2:CO ratio of about 1:1 and a space velocity of about 20,000/hr or, alternatively, at a temperature of about 150° C. with a O2:CO ratio of about 1.5:1 and a space velocity of about 80,000/hr.
