Abstract
|
|
|
|
A catalytic conversion of carbon monoxide has been studied in a coal combustion system. Three different catalysts were prepared by impregnating 0.2% platinum on three different types of supports, γ-Al2O3 pellets, ceramic foam and honeycomb. These catalysts have shown an excellent initial activities in the coal combustion system, but they were rapidly deactivated in repeated uses. Among these catalysts ceramic foam has shown to be better than others both in activities and durabilities. The main cause of deactivation seems to be ascribed to poisoning by zinc metal and sulfur compounds and to decrease in platinum surface area by sintering.
