Abstract

The invention specifically relates to a GPG-IV gasification and pyrolysis integrated top-spray reactor and production equipment and a technology. The technical problems such as low oil extraction rate, immature technology, low utilization rate of raw materials, serious wastage and inconspicuous economic benefit of existing coal-to-oil equipment are solved. Heat of gasification from upper and lower sections of the reactor is simultaneously supplied to a pyrolysis section. The heat source generated by gasification is fully utilized for secondary gasification of generated coke ash. Thus, one-step conversion of coal-to-oil can be realized, pyrolysis capability of a single reactor is greatly enhanced, and coal category adaptability is wide. According to the invention, the product is diversified; comprehensive energy efficiency and technologies such as conventional pulverized coal gasification, coal water slurry gasification, etc. are high; energy consumption is lower; use amount of water is small; and handling capacity is large. Gasification + pyrolysis + semicoke gasification integrated technology is realized. The invention has advantages as follows: the technology is mature; product quality is stable; the structure is simple and reliable; utilization rate of raw materials is high; oil extraction rate is high; energy is saved and environment is protected; the technology is economic and safe; and large-scale industrial production can be realized.

Description

technical field [0001] The invention belongs to the technical field of coal-to-oil, and specifically relates to a GPG-IV gasification pyrolysis integrated top injection reactor, production device and process, which realizes one-step conversion from coal to oil. Background technique [0002] Since the discovery of large-scale oil reserves in the Americas and the Middle East in the middle of the 19th century and the beginning of the 20th century, people have widely used oil as an energy source. In recent years, with the dwindling of oil resources, the international oil market is turbulent, which has brought adverse effects on the economic development of various countries. People will not forget the global economic recession caused by the two financial crises in 1973 and 1979-1980. At the same time, because oil is the basis of a huge petrochemical industry, it is used in industries such as plastics, fibers, paints, and medicines, and is also used in the production of basic foo...
