Abstract

The invention relates to a method for preparing a coal tar heavy oil hydrogenation catalyst. According to the method, great weight parts of ferric sulfide and ferric oxide are added to pulverized coal and mixed to be uniform, molybdenum, nickel, tungsten and cobalt mineral powder or metal salt water solutions with appropriate concentrations are added respectively according to different coal tars, the mixture is prepared into slurry by adding water, the slurry undergoes wet pulverization to enable molybdenum, nickel, tungsten and cobalt active components to be uniformly dispersed to the surface of the carrier pulverized coal, and simultaneously a high weight percent of ferric sulfide and ferric oxide active components are uniformly dispersed on the surface of the pulverized coal carrier. The coal tar heavy oil hydrogenation catalyst obtained according to the method disclosed by the invention not only has good dispersivity in coal tar heavy oil and higher catalyzing hydrogenation activity, but also can avoid catalyst agglomeration and aggradation in a coal tar heavy oil hydrogenation reactor to achieve good effect.

Description

technical field [0001] The invention relates to a coal tar heavy oil hydrogenation catalyst and a preparation method thereof, belonging to the technical field of hydrogenation catalysts. Background technique [0002] After decades of development, my country's coal chemical industry occupies a very important position in the chemical industry. The output of coal chemical industry accounts for about 50% of the chemical industry (excluding petroleum and petrochemical industry). The two basic chemical products of synthetic ammonia and methanol mainly use coal as raw material. In recent years, due to rising international oil prices, coal chemical industry has shown more and more advantages. Coal coking, coal gasification-synthetic ammonia-chemical fertilizer has become the main coal chemical industry in my country, and has been developing continuously and rapidly in recent years; The speed of technology introduction, development and industrialization construction has been acceler...
