    摘要: The present invention discloses a hydrofining catalyst. The catalyst has the following composition based on the total weight of the entire catalyst composition: 1-5%(wt.) nickel oxide, 12-35% (wt.) tungsten oxide, 1-9% (wt.) fluorine, and the balancing amount of composite alumina. Said composite alumina is composed of one or several kinds of micropore alumina and one or several kinds of macropore alumina, wherein the weight ratio of micropore alumina to macropore alumina is 75:25 to 50:50. The term "micropore alumina" in the context means the alumina in which the volume of the proe of diameter less than 80 angstrom occupies more than 95% of its total pore volume, while the term "macropore alumina" in the contest means the alumina in which the volume of the pore of diameter 60-600 angstrom occupies more than 70% of its total pore volume. The pore distribution mentioned above is determined by BET method of nitrogen adsorption at low temperature. This catalyst is especially suitable for the hydrofining of inferior distillates with high sulfur content and boiling range of 80-550.degree. C.

    摘要翻译: 本发明公开了一种加氢精制催化剂。 催化剂具有以下催化剂组合物总重量的组成:1-5%(重量)氧化镍,12-35%(重量)氧化钨,1-9%(重量)氟,和 复合氧化铝的平衡量。 所述复合氧化铝由一种或几种微孔氧化铝和一种或几种大孔氧化铝组成,其中微孔氧化铝与大孔氧化铝的重量比为75:25至50:50。 在本文中,术语“微孔氧化铝”是指直径小于80埃的原型体积占其总孔体积的95%以上的氧化铝,而比较中的术语“大孔氧化铝”是指氧化铝 其直径为60-600埃的孔的体积占其总孔体积的70%以上。 上述孔分布由低温氮吸附的BET法测定。 该催化剂特别适用于高硫含量和沸程为80-550℃的劣质馏分的加氢精制。
