On November 9, the demonstration project of rapid pyrolysis of low-grade pulverized coal of 1.2 million tons / year by Shaanxi Coal Mining Group Co., Ltd. was started at Mahuangliang Industrial Zone in Yulin, which is currently the first single-series megaton-class pulverized coal-fired heat Solution industrial demonstration device.
Li Qianglin, Secretary of Party Committee and Chairman of North Shaanxi Mining Company, introduced the project with a total investment of 2.9 billion yuan, including 1.2 million tons / year rapid pyrolysis of pulverized coal, 300,000 tons / year of coal tar suspended bed hydrogenation, 40,000 cubic meters / hour Hydrogen production, 4000 tons / year sulfur recovery devices, designed by Shanghai Sheng Bang Technology Co., Ltd. It is estimated that after the completion in October 2019, the sales revenue will reach 1.4 billion yuan.
It is understood that Shaanxi Coal Group, relying on relying on national key energy-saving clean coal conversion laboratory, independent research and development of low-grade coal rapid pyrolysis technology, and built in Yulin 20,000 tons / year industrial test device, the cumulative running time of more than 2000 hours , Passed the appraisal of the results organized by China United Petrochemical Association in September last year.The technology through the second-level pyrolysis reaction, the energy conversion efficiency of 80.97%, tar yield 17.11%, up to 155% of the benchmark gelatin tar yield .Not only tar production High-rate, semi-coke products clean, and more than 50% aromatic carbon content of hydrogenated naphtha.Not only that, through the 1.2 million tons / year low-grade coal pyrolysis industrial demonstration project of heavy coal tar suspended bed hydrogenation technology Industrial application, the further verification of the feasibility of technology at the industrial level is of great significance to the processing of heavy tar and once again seize the commanding height of modern coal chemical industry.
According to the experts in the industry, if 300 million tons of coal with an annual output of 500 million tons are subject to sub-quality conversion in Yulin, 50 million tons of oil products and nearly 150 million tons of clean coal-burning fuel will be produced, and the coal industry will make a qualitative leap.
Yang Zhaogan, Party Secretary and Chairman of Shaanxi Coal Group, said that by the end of the 13th FYP period, Shaanxi Coal Group will account for 94% of the total high-quality coal and coal will become the absolute superiority industry of Shaanxi Coal. Rapid pyrolysis of grade coal separation and conversion technology, and vigorously develop clean energy use of new energy industries, extend the product chain and enhance the value chain, to create a hundred years, "famous enterprises" laid the foundation.
