Hydroisomerization of benzene containing gasoline fractions on catalyst Pt/SO4 2––ZrO2–Al2O3. Transformation of the model and real feed
Abstract
Conversion of benzene containing naphtha on bifunctional catalytic system Pt/SO4 2––ZrO2–Al2O3 with different chemical compositions of support is studied. Results of hydroisomerization of model heptane-benzene mixture showed that the optimum catalytic properties possessed by the system, wherein the support comprises 67,8 wt.% alumina. For benzene containing fraction IBP–85 °C (23,7 wt.% benzene) of industrial origin it is found that the catalyst allows the complete removal of the arenes from benzene containing fraction at increasing its octane number up on 2,2–3,3 points by the research method while maintaining a high yield of liquid products (98,7 wt.%
or more).
