China Drying Network News With the advancement of technology and market expansion, there is a better solution for the supply of blue carbon raw materials and coke powder. It can be said that this brings bright prospects for the blue carbon enterprises. “We are about to fully commission 600,000 tons/year of solid pyrolysis of pulverized coal and pyrolysis to produce a 120,000 tons/year coal tar full-distillation hydrogenation unit. The raw material used is a low-volume pulverized coal. Once it is successfully tested, it will Help the Lancang enterprises to completely get rid of the constraints of lump coal.†Yang Zhanqi, general manager of Shenmu Oil-rich Energy Technology Co., Ltd. of Shaanxi Coal Chemical Group, said to reporters recently. He said that the solid pyrolysis technology for solids in pulverized coal was jointly developed by a rich oil company and a well-known institute. The principle is that coal is rapidly pyrolyzed at 500°C to 550°C to extract the light coal tar and coal gas. Due to the short time from the furnace to the tapping of the raw coal and the low temperature of the retorting, the secondary pyrolysis and polymerization of the coal tar is avoided, so the coal tar yield can be increased to more than 10% (on the basis of raw coal, the same below). In addition, the coal is pyrolyzed under the condition of air separation, and the by-product gas contains more than 70% of H 2 +CH 4 +CO and the calorific value exceeds 4300 kcal/m 3, which is twice the calorific value of the waste gas of general charcoal enterprises. More, very suitable for purification - methanation production of natural gas. Once the demonstration project for solid pyrolysis of pulverized coal solid pyrolysis has been successful, the charcoal enterprises will not only be able to get rid of the dependence on lump coal, but will also significantly increase the coal tar yield and the added value of coke oven gas, and increase the economic efficiency and competitiveness of the enterprise. For the blue carbon enterprise, the traditional practice is to use more lump coal to produce coke, and the powdered coal produced coke powder is neglected for a long time because of poor sales. However, with the application of new technologies, the use of coke powder is also expanding, and it occupies part of the coal market at a low price. Yang Zhanyi introduced to the reporter that after the cooperation between the oil-rich company and Tsinghua University and Sinosteel Anshan Thermal Energy Research Institute, they respectively conducted pilot tests on the slurryability of coke breeze-making coal-water slurry and coke-powdered anthracite-injected blast furnace injection at Jiu Steel and Anshan Iron and Steel respectively. The results show that the rheology and pulping properties of coal water slurry produced from coke batter are better than that of raw coal; the use of coke breeze instead of anthracite in blast furnace injection technology is no problem, and the injection ratio can reach 1/3 of the amount of coke. Many steel mills in the Bohai Rim region have even made it clear that as long as the blue carbon companies can ensure supply, they are happy to use cheap coke powder. Because the pulverized coal retorting technology has not yet been industrialized, the production of coke powder by traditional blue carbon companies is very small, and they cannot meet the demand for coke powder of large-scale steel mills with hundreds of thousands of tons and millions of tons of coke. Once the pulverized coal rapid pyrolysis industrialization demonstration device has been successfully applied and popularized, coke powder production has increased greatly, and it will be able to meet the demand for coke powder from steel plants. Steel mills will also become the largest buyers of coke powder, and the problem of coke powder outlets will naturally be solved. . “We used pulverized coal, coke breeze, and lignite as our main raw materials, and we used TRIG furnaces to conduct gas production experiments. All of them achieved good gas production effects, which not only validated the good adaptability of the coal in the TRIG furnace, but also proved gasification. With reasonable technical options, coke dust, lignite and other types of coal that are considered bad to use can also be used for clean and efficient use,†said Li Dapeng, assistant to general manager of Shaanxi Yanchang Petroleum Group. According to Mao Shiqiang, Chairman of Shaanxi Coal Chemical Group Shenmu Tianyuan Chemical Co., Ltd., improving coal utilization is the best option to solve the problem of coke powder outlets. Tianyuan is developing a coal-fired microwave catalytic pyrolysis technology that can maximize the lightness of coal. The quality components are extracted so that the coal tar yield can reach 15% or more. They first “pick-head†the coal, and obtain the clean fuel oil from the obtained coal tar catalytic hydrogenation. Then the blue carbon or coke powder with light components is sent to the nearby power plant or the company-owned power plant for combustion and power generation. , to achieve coal quality, grade efficient cleaning and utilization. "On September 1, we have signed a cooperation agreement with the Hami regional government with a total investment of 11 billion yuan. We plan to build a 1,000-ton-per-year coal mining plant with an area of ​​3,000 mu and 1,600,000 yuan in the Maohu Lake Industrial Park in Hami. Ton/year coal tar hydrogenation and large-scale power generation projects will eventually form a 10-million-ton coal tar hydrogenation production capacity and a world-class coal-coke-electricity-thermal integration demonstration base to solve the problem of rapid carbonization of pulverized coal. At the same time as the efficient use of coke powder, we have explored a new path for green and sustainable development for the coal chemical industry.†Mao Shiqiang is full of confidence in the prospects of the blue carbon industry.
