Conversion of n-Heptane, n-Butane, and Their Mixtures on Catalytic Systems Al2O3/WO 4 2– ∙ZrO2 and HMOR/WO 4 2– ∙ZrO2

The conversion of n-C7H16, n-C4H10 and mixtures of C7H16: n-C4H10 = 1: 0.3 on the composite catalysts Al2O3/WO 4 2– ∙ZrO2 (A-WZ) and HMOR/ WO 4 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.
