Clean-coal Industry Make Great Strides

Article Category: Business

Author Name: xia zihui

China's oil and gas resources severity shortage, already more than 50% of the external dependency cordon. Coal is our country main energy, future will still in our country's energy consumption structure long-term dominant. However, coal traditional using technology, low efficiency, heavy pollution and unable to make full use of its resources value, resulting in huge waste of coal resources.

Chinese academy of sciences, focusing on the national clean-coal technology, based on the strategic needs original innovation, strengthen the application demonstration, decades unremitting, in coal oil, coal glycol, methanol olefin cleaner fuels such as coal and chemical production base areas, form a series of independent intellectual property industrialization technology, broke the foreign technology monopoly, fill in a number of technical gaps, become the world coal chemical recycling economy technology has important influence on r&d strength.

Aimed at the demand of the country, the strategies of the coal cleaning efficient utilization technology system

With the rapid development of our economy, the coal consumption is growing rapidly. 2009 China coal consumption reaches 3.05 million tons, making up our primary energy consumption about two-thirds of the total.

Cas shanxi coal chemical research institute WangJianGuo researchers say, "development of efficient and cleaner coal comprehensive utilization technology to realize the energy saving and emission reduction, is China's energy industry the development inevitably choice."

In the national energy technology in the 11th five-year development plan, China will clean-coal technology as priority development of advanced applicable technology, mainly including coal processing, coal combustion, coal conversion efficiency clean, pollution emission control and waste treatment, etc.

Cas high technology research and development council deputy director, told reporters LiuGuiJu around national clean-coal technology strategic needs, Chinese academy of sciences in the past 30 years, on the basis of research accumulated around key core technology, through a series of major and forward-looking layout, the centralism develops tackling, and indirect method in coal synthetic oil, coal glycol, methanol olefin, coal ash melting circulating fluidized bed combustion, gather gasification technology etc. Several core element technique realized the cluster breakthrough, formed a batch of independent intellectual property rights of the industrialization technology, and successfully completed industrial demonstration projects.

Based on the forefront of science, unremitting make clean-coal technology leading position

"Review clean-coal technology innovation process, a few big key areas of breakthroughs through generations of number 10 years of effort", Chinese academy of sciences dalian chemical physics research institute ZhangTao researchers say, "based on the forefront of science, unremitting originality innovation and technology development, make us in clean-coal technology of the world's leading position."

"Since the 1970s, the United States, Germany since the big enterprise have been studied by using coal instead of oil in the methanol production technologies, in order to reduce dependence on oil. Realize this technical route of key lies in breakthrough methanol olefin technical bottleneck", dalian hydrates institute vice director, DMTO project total principals LiuZhongMin researchers say, "conquer this difficult problem that is the core of r&d out proper catalyst".

As early as "June" period, methanol olefin catalyst research has been listed as major issue of Chinese academy of sciences, In the early 1990s, dalian hydrates in international pioneered by and by making dimethyl ether "syngas low carbon olefins new process methods", In 2004, dalian and related enterprise cooperation hydrates, built the world's first DWT methanol olefin industrial test device, in 2006 complete industrial test, 2010 in August, shenhua group 1.8 million tons methanol making low carbon olefin (DMTO) project feeding trial run a successful, current device running well, stable performance, indicating our country with independent intellectual property rights of the coal to olefin technology industrialization and commercialization practice of success.

So far, cas dalian hydrates, scientific and technical workers by generations after, finally out an original Chinese technical route, conquer methanol making low carbon olefins problem, for thecarbonificated industry chain "welding on" key ring.

Ethylene glycol is also a kind of strategic chemical basic raw material, adopts mainly oil route preparation. In 1982, cas fujian material structure institute began to consider alternative to coal oil ethylene glycol for synthesis of new technology. After nearly 30 years of efforts, China has successfully developed precincts of independent intellectual property coal glycol complete set technology, built the world's first 20 DWT industrial demonstration projects.

Since the 1980s, Chinese academy of sciences at the beginning of shanxi institute of coal chemistry launched coal oil industrial technology research. Ipp original high temperature plasma bed synthetic oils technology and fee torsten synthesis catalyst production technology, applied to three 16 tons demonstration project, various indexes have reached the international advanced level, and marks China has complete mastery of the advanced and efficient coal oil industry technology.

Insist on court to cooperate, multiparty ratajczak casting manufacture-learning-research techniques popularization system

For many years, Chinese academy of sciences by systemic basic research for its source, continuously enhancing pilot-scale, strengthen cooperation with universities, enterprises and local government cooperation.

In coal oil technology development process, cas hand through the knowledge innovation project major project support coal oil technology research and development, on the other hand and shanxi provincial people's government signed "courtyard", and cooperative frame agreement joint domestic large coal enterprises in shanxi LuAn mining group, Inner Mongolia Iraq tai group and shenhua group etc, carried out by thousand tons synthetic oils &1-butene automethathesis and research and development. In successive years to achieve continuous stability after the operation, 2006, shanxi MeiHuaSuo joint five large domestic coal enterprises was established "zhongke synthetic oils technology Co., LTD.", formed China coal oil industry development technical support entity.

Circulating fluidized-bed combustion technology is of Chinese academy of sciences from the 1980s began to deploy the coal clean burning new technology. Cas engineering thermal physical researches in more than 20 years of practice widespread.i went out a basic research -- -- -- technology demonstration pilot study of industrialization promotion technical transformation path.
