Deep Oxidation of Hydrocarbons on Polyoxide Nickel- Containing Catalysts

Abstract

The data on investigation of polyoxide Ni-Cu-Cr/2 % Ce/θ-Al2O3 catalysts on carriers with specified properties for deep oxidation of hydrocarbon - toluene, which has a strong toxic effect on living organism and flora, are given. The influence of technological parameters (temperature, space velocity, concentration of toluene in a mixture with air) on the completeness of the conversion of toluene (to CO2 and H2O) on an effective polyoxide catalyst has been studied. It was shown that the synthesized polyoxide Ni-Cu-Cr catalyst supported on 2 % Ce/θ-Al2O3 provides 98.8 % conversion of toluene to CO2 in the oxidation reaction of toluene at a space velocity of 5×103 h-1, 723 - 773 K and the content of toluene 100 - 570 mg/m3 in mixture with air.
