摘要：

The conversion of benzene-containing gasoline fractions on the bifunctional Pt/ - ZrO2-4Al2O3 catalytic system with different compositions of the support is studied. Using the results from hydroisomeriza- tion of a heptane-benzene model mixture, it is shown that a system with 67.8 wt % of aluminum oxide in its support has the best catalytic properties. For the IBP-85°C industrial benzene-containing fraction (23.7 wt % of benzene), it is established that the given catalyst ensures the complete removal of arenes from the benzene- containing fraction while raising its research octane number by 2.2-3.3 points and retaining a high yield of liquid products at levels of 98.7 wt % and higher. © Pleiades Publishing, Ltd., 2013.
