Problems solved by technology

CN1205314C discloses a method for preparing heavy oil hydrogenation demetallization and desulfurization catalysts. Two types of composites are used for the carrier alumina, one of which is alumina powder calcined at 1100°C. This method can form more pores of 15 nm or more. The pores are penetrating, but still too small for the asphaltene micelles, which is not conducive to the demetallization reaction of heavy oil
Some of these methods require high temperature, some require very expensive raw materials, or the by-pr

Abstract

The present invention relates to a heavy oil hydrogenation protection catalyst, preparation and applications thereof. According to the catalyst, Al2O3 or SiO2-containing Al2O3 is adopted as a carrier; a carrier pore volume is 0.98-1.15 ml/g; a specific surface area is 340-380 m<2>/g; pore distribution is as the follow: the amount of the pore volume of pores with a pore diameter of less than 5 nm is 10-15% of the amount of the total pore volume, the amount of the pore volume of pores with a pore diameter of 5-15 nm is 50-55% of the amount of the total pore volume, and the amount of the pore volume of pores with a pore diameter of more than 15 nm is 25-40% of the amount of the total pore volume; the catalyst is loaded with nickel-molybdenum-sulfur, nickel-tungsten-sulfur, molybdenum sulfide, tungsten sulfide, cobalt-molybdenum-sulfur, cobalt-tungsten-sulfur, nickel-cobalt-molybdenum-sulfur, nickel-cobalt-tungsten-sulfur or cobalt-molybdenum-nickel-tungsten, and the loaded material is combined with Ni2P to form the composite catalyst. The catalyst has characteristics of suitable pore size, high metal melting ability, small active ingredient scale, good dispersity and high catalyst activity, and is suitable for heavy oil and heavy oil protection catalysts.

Description

technical field [0001] The invention relates to a catalyst for the hydrogenation of a supported composite sulfur and phosphide, as well as its preparation and application. Background technique [0002] With the increasing weight and quality of petroleum, it has brought more and more difficulties to petroleum processing. At the same time, the market demand for light oil products is increasing year by year. Therefore, the development of heavy oil deep processing is an urgent task for the oil refining industry. As the main processing method, heavy oil hydrogenation technology is facing great challenges. It is urgent to develop better heavy oil hydrogenation technology and activity. A better and more stable heavy oil hydrogenation catalyst. For the hydrogenation of heavy oil (especially heavy oil), the pore size and pore volume of the catalyst will directly affect the activity of the catalyst. [0003] For heavy oil macromolecules, it is necessary to drill through holes for me...
