Abstract
A process for preparing catalysts for hydrodesulfurization which have fine pores sharply distributed in the range of 50 to 200A by the steps of adding a molybdate to a water soluble aluminum complex represented by the general formula Al.sub.n (OH).sub.m X.sub.3n.sub.-m (wherein n>1, 3n>m and X is an anion) to obtain a uniform solution composition, treating the same hydrothermally, then adding a member selected from the group consisting of molybdenum and tungsten compounds and one or more members selected from the group consisting of iron, cobalt and nickel compounds, further adding and mixing with one or more members selected from the group consisting of polyvalent higher alcohols, high-molecular organic substances and amine group substances and then treating the mixture in such usual ways as drying, calcinating, grinding, moisture adjusting, molding, roasting and the like.
