催化重整过程是被广泛用于提高汽油辛烷值的一种方法。该过程可以将初馏点85,100,120℃及终馏点180℃的重馏分汽油进行改质。为了改善轻馏分汽油的辛烷值特性,应该掌握C_5～C_6烷烃的各种异构化方法。1990年在乌法炼油厂利用铝铂催化剂对直馏汽油馏分进行选择性加氢裂化低辛烷
Catalytic reforming is a widely used method to increase the octane number of gasoline. The process can be 85% of the initial boiling point 100,120 ° C and the end point of 180 ° C heavy-duty gasoline reforming. In order to improve the octane number of light-fraction gasoline, it is necessary to know various isomerization methods of C_5 ~ C_6 alkanes. 1990 Selective hydrogenation of straight-run gasoline fractions using aluminum-platinum catalysts at the Ufa refinery Low-octane
