China's coal pyrolysis technology reaches international advanced level

China's coal resources are abundant, but about half of them are low-grade coal with high water content and low calorific value. Recently, Beijing Shenwu Group created a coal pyrolysis technology with independent intellectual property rights, which can not only improve the quality of coal, convert inferior coal into high-quality coal, but also extract China’s urgently needed oil and gas and other energy products from coal. It is estimated that using this technology, about 200 kilograms of oil and natural gas resources can be extracted per ton of inferior coal.

The scientific and technological achievements of the key technology and equipment for thermal decomposition of rotary coal in thermal reactors, which have just been identified by experts from the National Energy Administration, were integrated by the Beijing Shenwu Environmental Energy Technology Group Co., Ltd., which lasted five years. The company's self-developed regenerative radiant tube combustion technology and rotary bed pyrolysis equipment have innovatively built a number of technologies including built-in partitioning of radiant tubes, subsection heating control of pyrolysis process sections, and rapid export of multiple oil and gas channels. Rotary bed coal pyrolysis technology and equipment with independent intellectual property rights.

The appraisal committee chaired by Academician Fei Weiyang of the Chinese Academy of Sciences unanimously believes that this achievement has achieved breakthroughs in key technologies. The core equipment, the non-thermal-carrier-based regenerative rotary bed, is stable in operation, highly automated, and is easy to operate. The technology, which has high tar yield, high thermal efficiency, and advanced technical indicators, is an innovative technology for the pyrolysis of lignite and low metamorphic bituminous coal, reaching the international advanced level.

Shen Qin Group, deputy general manager and executive dean of the Institute Wang Qinya said that last year China’s total coal consumption was 3.42 billion tons of standard coal. If this scientific and technological achievement is used, more than 680 million tons of oil can be extracted from medium-low metamorphic coal. Natural gas resources.
