It is reported that all walks of life have reached a consensus on the future development of coal chemical industry: 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 that the coal chemical industry seeks new breakthroughs
.
On June 5, at the seminar on new coal gasification technology and coal-to-natural gas development sponsored by the Coal Chemical Professional Committee of China Petroleum and Chemical Industry Federation, Gu Zongqin, current president of the Petroleum and Chemical Industry Planning Institute, said frankly that the development of coal chemical industry is facing many difficulties
.
At present, the current situation of coal chemical industry is overheated, blind investment and following the trend, in fact, some projects approved by the state have also been suspended and
suspended.
Gu Zongqin pointed out that there are three reasons for the difficulty in the development of coal chemical industry: first, the energy efficiency of coal chemical industry is too low, including coal-to-liquid, coal-to-natural gas, and coal-to-olefin, the energy efficiency conversion of the entire reaction path can only reach about 40%; Second, the national level has begun to crack down coal chemical environmental protection projects, and at present, the Ministry of Environmental Protection has raised many problems on coal chemical projects, which have a great impact on the industry and beyond; Third, the biggest challenge faced by the coal chemical industry is not only environmental protection problems, but also the problem of efficiency, the overall cost of coal chemical industry is high, and equipment investment accounts for nearly 60%
of the project cost.
The construction time is long, and the high engineering and time costs affect the overall efficiency
of the industry.
Gu Zongqin put forward two new ideas for the future of coal chemical industry, one is to change the metallurgical furnace to the coal chemical furnace process, and the other is coal direct catalysis technology
.
ENN launched the company's coal-catalyzed gasification to SNG technology, which attracted the attention
of many professionals.
The catalytic gasification technology has several compelling advantages, namely coal grading conversion, improved energy efficiency and system capacity; Realize methane and tar co-production, and the process economy is high; Tar and gas separation adopts indirect condensation, and no coke washing wastewater is generated
.
ENN says the technology is efficient, low-cost and industrializable
.
However, all this has yet to be verified by industrialization
.
Bi Jicheng of the Coal Gasification Technology Center of ENN Energy Research Institute said that the coal gasification technology will improve the efficiency of coal direct synthesis of methane, shorten the coal gasification reaction path, and have broader requirements for coal types.
The energy conversion rate is high, and the technology adopts the graded conversion technology combining coal pyrolysis, catalytic gasification and combustion, and the process thermal efficiency is as high as 72%.
Reduce CO2 emissions
while increasing methane yield.
In addition, in view of another difficulty of coal catalytic gasification technology, that is, the non-recoverability of catalysts, ENN said that the gasification technology uses indirect condensation technology for coal gas cooling, 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 say that if the cost of catalysts is high, it will also put pressure on industrial scale, and if low-cost catalysts can be developed, catalytic gasification technology will create a new milestone
in the field of coal gasification.
Industry insiders said that once this coal catalytic gasification technology can be successfully demonstrated and put into production, it will be a new direction
for the development of coal chemical industry.
At present, the technology is undergoing the preliminary design of the thousand-ton demonstration project, and it is expected to complete the construction and commissioning of the demonstration device within 2-3 years to achieve industrial operation and promotion
