Catalytic combustion of carbontetrachloride

The catalytic combustion of carbontetrachloride was investigated on metal oxide catalysts coated on the monolith support. The prepared catalysts were tested at the different temperatures between 300 and 800 degrees C and the varying GHSV values with an excess air ratio of 3100%. The catalyst, having the composition of 18% Cr2O3, 2% Ce2O3 and 80% gamma-Al2O3, was found to be suitable for the almost complete destruction of carbontetrachloride. The operating conditions were proposed as 5702 h(-1) for GHSV, 3100% for the excess air. The temperature should be slightly higher than 800 degrees C. The reaction rate expression was found to be independent of oxygen partial pressure and strongly dependent on carbontetrachloride partial pressure.
