    摘要： The present invention relates to a hydrocracking catalyst containing nickel, tungsten, fluorine, zeolite as well as alumina, said catalyst is composed of, based on the total weight of the catalyst, 0.5-5.0 wt % fluorine, 2.5-6.0 wt % nickel oxide, 10-38 wt % tungsten oxide, and a catalyst carrier. Said carrier is composed of 20-90 wt % alumina and 10-90 wt % zeolite wherein the zeolite is mesopore or macropore zeolite of an acidity strength value 1.0-2.0 mmol/g determined by NH.sub.3 -TPD, the alumina is the alumina of an acidity strength value 0.5-0.8 mmol/g determined by NH.sub.3 -TPD. Said catalyst possesses good desulfurization activity, denitrogenation activity, and higher selectivity with respect to middle distillates than that of the prior art.

    摘要： Disclosed is a process for reducing sulfur and olefin contents in gasoline, comprising contacting gasoline feedstock and hydrogen with a hydrorefining catalyst and an paraffin-modification catalyst. The effluent of the process is separated to obtain a hydrotreated gasoline fraction free of mercaptan and having a low content of sulfur, e.g. less than 200 ppm, a low content of olefins, e.g. less than 20% by volume, and little octane loss. The hydrotreated gasoline fraction can be used as blending component of a final gasoline product.
