“Eat Dry Pressing” Coal Production Oil and Gas Products Shaanxi Pulverized Coal Rotary Pyrolysis Technology Leading International
(Reporter Cheng Jingfeng) On November 26, the “Large-scale Industrialized Low-level Pulverized Coal Rotary Pyrolysis Technology” developed by Shaanxi Coal Group Shenmu Tianyuan Chemical Co., Ltd. and China Chemical Engineering Group Hualu Engineering Technology Co., Ltd. took 7 years to develop Development and Application "passed the scientific and technological achievements appraisal in Beijing. The appraisal committee composed of 9 experts such as Xie Kechang, an academician of the Chinese Academy of Engineering, agreed that the technology has reached the international leading level, and it is recommended that a million-ton large-scale chemical industry demonstration and promotion should be carried out as soon as possible.
It is understood that this technology uses Yulin's abundant pulverized coal as raw material and pyrolyzes it through a rotary reaction furnace to generate high-temperature oil and gas and upgrade coal, which "cleans up the coal". The main product, coal tar, is a high-quality raw material for deep processing to produce lightweight fuels, new carbon materials and high value-added chemical products; pyrolysis gas is a raw material for LNG, LPG, and chemical utilization. This technology overcomes the problems of equipment enlargement and pipeline blockage, and has obtained 12 invention patents and 44 utility model patents.
At the end of 2018, the 600,000 tons / year industrial demonstration unit of this technology was completed and operated. As of November 6, 2019, a total of 142,400 tons of raw coal was processed, 13,000 tons of coal tar was produced, and 16.38 million cubic meters of pyrolysis gas was produced. The quality of coke powder was 86,100 tons, the sales income reached 100 million yuan, and the profit was 11.386 million yuan.
Experts said that coal tar can be used to produce clean oils and can replace petrochemical diesel and naphtha. This is of positive significance for ensuring national energy security in the context of international energy tensions. At the same time, the technical device consumes less water and is suitable for promotion and use in areas with abundant coal resources and lack of water resources.
Based on the completion and operation of a 600,000-ton / year industrial demonstration unit, Shaanxi Coal Group Shenmu Tianyuan Chemical Co., Ltd. is promoting the implementation of a 6.6 million-ton / year pulverized coal resource purification and quality utilization (technical transformation and upgrade) demonstration project to achieve pulverized coal Coupling and innovation of new technologies such as upgrading technology and lightening of coal-to-liquids. This project was listed as a major project of "Made in China 2025" Shaanxi Implementation Opinions.
