@ At least one decomposable molybdenum dithiocarbamate compound is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable molybdenum dithiocarbamate compound is then contacted in a hydrofining process with a catalyst composition comprising a support selected from the group consisting of alumina, silica and silica-alumina and a promoter comprising at least one metal selected from Group VIB, Group VIIB and Group VIII of the Periodic Table. The introduction of the decomposable molybdenum dithiocarbamate compound may be commenced when the catalyst is new, partially deactivated or spent with a beneficial result occuring in each case.
将至少一种可分解的二硫代氨基甲酸钼化合物与含碳氢化合物的进料流混合,然后在加氢精制工艺中将含有这种可分解的二硫代氨基甲酸钼化合物的含碳氢化合物进料流与催化剂组合物接触,催化剂组合物包括从氧化铝、二氧化硅和硅-氧化铝组成的组中选出的载体,以及从元素周期表第 VIB 族、第 VIIB 族和第 VIII 族中选出的至少一种金属组成的促进剂。 可分解的二硫代氨基甲酸钼化合物的引入可在催化剂是新的、部分失活或失效时开始,在每种情况下都会产生有益的结果。
