Oxidation Of Carbon Monoxide

The oxidation of carbon monoxide by oxygen using two catalysts prepared by two different methods has been investigated. In the first method, catalyst prepared by immersing γ-Al2O3 into the hexa-chloroplatinic acid solution at 80oC for 4 h, resulted Pt/γ-Al2O3 catalyst having platinum highly dispersed on the support. While that of immersing γ-Al2O3 in the hexa-chloroplatinic acid solution at room temperature for 12 h, produced Pt/ γ-Al2O3 catalyst where platinum dispersion was much lower. Catalytic activity test showed that platinum well dispersed on the support enhanced the activity for oxidation of carbon monoxide. The platinum impregnated at room temperature resulted in the poor activity.   Keywords: platinum catalyst, alumina, supported material, oxidation

Preparation Conditions

The effect of saturation of support with acetone and of subsequent heat treatment on the pore structure was studied for two types of activated carbon and platinum hydrogenation catalysts prepared from them. The observed distribution of the pore volumes with respect to the pore radii was compared with the initial pore structure of the untreated carbon. Changes in the pore distribution were found even in mild preparation conditions (calcination and reduction at 100 to 300 °C). These changes are particularly pronounced in the region of bulkier macropores and depend on the carrier nature. Coating of support with platinum does not affect the support pore structure in the preparation conditions applied.
