New ideas of coal catalytic gasification technology or coal forming chemical industry

held a seminar on the development of new coal gasification technology and coal to natural gas held by the coal chemical professional committee of China Petroleum and Chemical Industry Federation on June 5, Gu zongqin, the current president of petroleum and Chemical Industry Planning Institute, put forward two new ideas for the future development of coal chemical industry, one is to change metallurgical furnace to coal chemical furnace, the other is direct coal catalytic technology.

Gu zongqin said that Xinao group has launched the company's coal catalytic gasification technology to produce synthetic natural gas, which has attracted the attention of many professionals. The catalytic gasification technology has several remarkable advantages, namely, coal classification conversion, improving energy utilization efficiency and system capacity; realizing the co production of methane and tar, with high process economy; the separation of tar and gas adopts indirect condensation, and no coke washing wastewater is generated. ENN said the technology is efficient, low-cost and can be industrialized. However, all this has yet to be verified by industrialization. The experimental data can not explain everything, industrialization is the way out for testing technology.

reporter from energy verified relevant issues with Bi Jicheng, coal gasification technology center of new Austrian Energy Research Institute. President Bi said that the coal gasification technology will improve the efficiency of direct synthesis of methane from coal, shorten the coal gasification reaction path, and have broader requirements for coal types. At present, tests on anthracite, sub bituminous coal, lignite and bituminous coal have been completed. The energy conversion rate is high. The technology uses the coal pyrolysis, catalytic gasification, combustion combined with the hierarchical conversion technology, the process thermal efficiency is as high as 72%.

and

can increase methane yield and reduce carbon dioxide emission. In addition, in view of another difficulty of coal catalytic gasification technology, i.e., the non recyclability of catalyst, Xinao said that indirect condensation technology is adopted for gas cooling in the gasification technology, which does not produce coke washing wastewater, and the undecomposed water in the furnace is used for catalyst recovery, and the catalyst recovery rate can be as high as 97%. However, some people in the industry said that if the cost of catalyst is high, it will also bring pressure on the industrialization. If a low-cost catalyst can be developed, the catalytic gasification technology will create a new milestone in the field of coal gasification. However, at the same time, Bi Jicheng also pointed out that the technology is facing two major difficulties. First, the effect of catalyst and coal ash reduces the ash melting point, which may cause fluidization. Second, the matching of operation and reaction of high pressure fluidized bed gasifier. Some people in the industry of

and

said that once this technology can be successfully demonstrated and put into production, it will be "very promising". Once this technology is mature, it may be a new development direction of coal gasification. At present, Xinao has completed the preparation of feasibility study report of Xinao Ulanqab coal pressurized catalytic gasification demonstration project with an annual output of 200 million standard cubic meters of natural gas with a total investment of 1.56 billion yuan, and has signed cooperation agreements with many large chemical enterprises, such as saiding Engineering Co., Ltd., CNOOC, China Science synthetic oil and Sinopec. At present, the preliminary design of the 1000 ton demonstration project is under way. It is expected to complete the construction and commissioning of the demonstration device in 2-3 years, so as to realize the industrial operation and promotion.

and

coal chemical industry meetings are frequent recently, and coal chemical enterprises and experts from all walks of life discuss coal chemical industry development, environmental protection, 13th five year plan and other aspects. The future development of coal chemical industry seems to reach a consensus: coal chemical industry is still a sunrise industry, but the current development needs to slow down and move forward cautiously. The most important thing is to seek new breakthroughs in coal chemical industry.
