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.
