At the 6th National Petroleum Coke-Carbon Industry Chain Industry Forum held in Tianjin from October 30th to November 1st, experts at the meeting pointed out that the carbon industry should make full use of the advantages of China's petroleum and coal by-product resources and break through special carbon materials. Production technology bottlenecks, expanding the application of carbon materials.
The experts at the meeting unanimously emphasized that China's development of high-end carbon materials industry has resource advantages. Taking coal tar as an example, the current output is 12 million to 12.5 million tons, accounting for about 2/3 of the global output. It is the largest supplier of coal tar pitch and coal-based chemicals in the world, but the actual processing capacity of coal tar in China is only 500. 10,000 tons, the processing capacity of a single set of processing equipment is small and scattered, so the use of coal tar deep processing of special carbon materials has great room for development.
Yan Wenping, general manager of Tianjin Jinmei Carbon Materials Technology Development Co., Ltd., proposed that the development of special carbon materials urgently needs to overcome key technologies such as raw material selection and ratio, raw material preparation, large-scale billet impregnation, and purification of graphitization. At present, there are only a few companies in China that can produce isostatic graphite, but there is a big gap between foreign products in terms of product quality, performance and specifications. Nuclear graphite is mostly dependent on imports; it is used to produce high-power graphite electrodes and ultra-high power. The annual output of needle-shaped coke of graphite electrode is only 50,000 tons, and the market share is very low. The mesophase carbon microsphere material which can be used to produce lithium ion battery materials and high-performance composite materials has high technical requirements, few production enterprises, and high price. 180,000 yuan / ton, greatly limiting the development of related products. In addition, the production processes for materials such as spherical activated carbon and pitch-based carbon fibers used in the biomedical and photovoltaic industries are also in urgent need of improvement.
Chen Guoqiang, executive vice president and professor-level senior engineer of China Carbon Industry Association, believes that although China's special carbon materials have made great progress in production technology, equipment, product specifications and quality, but also for the production of special carbon materials for high-end products. There is still a big gap between the technical level and the developed countries in Europe and America. Not only is the production scale small, but the product grade is also low. He introduced that special carbon materials are one of the fastest growing and most promising new materials in the current industrial new materials, and have become an indispensable high-performance engineering material in the world today. Special carbon materials are not only widely used in traditional industries such as metallurgy, chemical industry, machinery, but also in emerging industries such as aerospace, new energy, communication, bioengineering, etc., especially isostatically pressed graphite materials, which are used for solar crystal silicon. Key materials in the fields of batteries, fourth-generation nuclear reactors, EDM, manned aviation, energy conservation and emission reduction.
