Abstract

The invention discloses a catalyst for producing fuel oil, comprising a carrier and an active component. The catalyst is characterized in that the active component is a brominated compound, and the carrier has a molecular sieve. When the provided catalyst for producing fuel oil is used for producing fuel oil, coal tar hydrogenation modification is not needed, a technical process for preparing fuel oil by using coal tar is simple, a production technology is easy to master, and the equipment investment is low. Compared with the prior art for preparing fuel oil by using coal tar, the fuel oil prepared by using the catalyst provided by the invention has high yield, and moreover, the color of the prepared coarse fuel oil can not darken when stored for a long period. A test shows that when the coal tar is used for preparing the fuel oil by using the catalyst, the yield of the fuel oil is over 64 percent.

Description

technical field [0001] The invention belongs to the field of catalyst preparation, in particular to the aspect of a catalyst for preparing fuel oil from coal tar. Background technique [0002] How to effectively utilize coal resources and make them meet the requirements of environmental protection has always been the research direction of various countries. Coal tar is one of the products of coal dry distillation and coal gas production. In my country, the deep processing of coal tar has attracted much attention in the 1950s and 1960s, and a lot of money and manpower have been invested in research. Due to the discovery of oil in Daqing, Liaoning, Shandong, Henan, Xinjiang and other places, since the 1960s and 1970s, my country's research and development of coal tar deep processing to produce high-quality and environmentally friendly liquid products has almost stagnated. Until the end of the 1990s, with the increasing consumption of petroleum resources worldwide and the inc...
