摘要： A catalyst composition useful in the hydroprocessing of a sulfur- and metal-containing hydrocarbon feedstock comprises 1.0-5.0 weight percent of an oxide of nickel or cobalt and 10.0-25.0 weight percent of an oxide of molybdenum, all supported on a porous alumina support in such a manner that the molybdenum gradient of the catalyst has a value of less than 6.0 and 15-30% of the nickel or cobalt contained in the catalyst is in an acid extractable form. The catalyst is further characterized by having a total surface area of 150-210 m.sup.2 /g, a total more volume of 0.50-0.75 cc/g, and a pore size distribution such that pores having diameters of less than 100A constitute less than 25.0%, pores having diameters of 100-160A constitute 70.0-85.0% and pores having diameters of greater than 250A constitutes 1.0-15.0% of the total pore volume of the catalyst. A method for the hydroprocessing of a sulfur- and metal-containing hydrocarbon feedstock comprises contacting the feedstock with the abovedescribed catalyst and hydrogen in a maner such that the catalyst is maintained at isothermal conditions and is exposed to a uniform quality of feed. The method is particularly effective in achieving desired levels of hydrodesulfurization in vacuum residual feedstocks.

摘要： Disclosed is a process for the amination of polyols to form primary amines which comprises reacting a polyoxyalkylene alcohol or polyol having a molecular weight of from about 230 to 5000 and ammonia in the presence of hydrogen over a catalyst consisting essentially of 10 to 35 wt % nickel, 1 to 20 wt % copper and 0.1 to 2.0 wt % optionally chromium or molybdenum promoter impregnated onto a .theta.-alumina support at a temperature of 100.degree. C. to 300.degree. C. and a pressure of 1000 psig to 3000 psig wherein the .theta.-alumina support results from calcining .gamma.-alumina or pseudo-boehmite for 2-4 hours at 900.degree.-1100.degree.
