Conversion of n-Heptane, n-Butane, and Their Mixtures on Catalytic Systems Al2O3/WO42–∙ZrO2 and HMOR/WO42–∙ZrO2

Resumo

The conversion of n-C₇H₁₆, n-C₄H₁₀ and mixtures of C₇H₁₆: n-C₄H₁₀ = 1: 0.3 on the composite catalysts Al₂O₃/WO₄^2– ∙ZrO₂ (A-WZ) and HMOR/ WO₄^2– ∙ZrO₂ (M-WZ) at atmospheric pressure, H₂/hydrocarbon = 3 and temperatures of 140-200°C was studied. It was found that a mixture of C₇H₁₆: n-C₄H₁₀ on M-WZ with high selectivity is converted into C₅–C₆ isomers. An assumption was made about the mechanism of the formation of the bimolecular intermediate C11, which decays earlier than occurs the formation of the products of the conversion of the mixture C₇H₁₆: n-C₄H₁₀.
