CATALYTIC COMBUSTION OF CARBON MONOXIDE ON COPPER OXIDE - EFFECT OF CARBON DIOXIDE

The effect of carbon dioxide on the catalytic combustion of carbon monoxide on copper oxide was investigated. The carbon dioxide content of the feed stream was varied from 0 to 10% with the total gas flow maintained constant at 400 liters (25°C., 1 atm.) per hour. The initial concentration of carbon monoxide was varied from 300 to 1150 p.p.m., and reaction temperatures ranged from 60° to 134°C. Correlation of the experimental data with the simple power law rate equation showed that the reaction order increased from 0.3 to 0.8 for carbon dioxide concentrations ranging from 0 to 10%. A more general correlation of the kinetic data with a single rate equation for the entire range of carbon dioxide concentration was achieved. © 1969, American Chemical Society. All rights reserved.
