What is the current progress of gray polymerization?

Ash pyrolysis technology from atmospheric pressure to pressurized conditions； From laboratory tests to pilot production of the manufacturing facility, everything has been completed. It has entered the stage of mass production.

Shijiazhuang Jinshi uses gray fusion; it seems to be in operation, but the specific details are not clear.

I heard that Taihua has been operating the equipment for some time now, and the distributors and central tubes are being modified by the company itself; however, it’s not clear what the consumption levels are. Everyone might want to share their insights on this

Your post: There’s an explanation in the article on gray fusion at http://bbs.hcbbs.com/thread-309257-1-1.html, right? After more than 20 years of research and development as well as scale-up in industrial applications, the ash fusion fluidized bed gasification technology has led to the maturation of low-pressure gasification techniques, which are now used for converting raw materials gas in nitrogen fertilizer plants and for building new methanol synthesis facilities. This gasification technology can be used with coal of varying ash contents and ash fusion temperatures, boasts high process efficiency, and is suitable for the characteristics of China’s resources. To this end, with the support of the Shanxi Provincial Development and Reform Commission, the \"Shanxi Province Powder Coal Gasification Engineering Research Center,\" established through a partnership between the Shanxi Institute of Coal Chemistry of the Chinese Academy of Sciences and Shanxi Jinmei Group, is building a pilot-scale platform for 3.0 MPa pressurized ash-melting fluidized-bed powder coal gasification. This platform was completed by the end of 2006; pressurized gasification tests are scheduled to take place in March 2007, and by that same year the design software package for industrial-scale pressurized ash-melting fluidized-bed coal gasification systems is expected to be developed, thereby creating a large-scale technology for such gasification that possesses independent intellectual property rights in China and is suited to the characteristics of Chinese coal.

Jincheng uses ash polymerization technology for coal-to-oil production, but it has not yet been put into operation.

The situation of gray fusion polymerization in China seems quite complex at the moment. Units related to gray fusion technology: Shanxi Coal Chemical, Qinjin Company, Qinen Tianji Company, and US SES. The patent dispute between the Shanxi Coal Chemistry Institute and Qinjin Company sees each side holding its own arguments, and the conflict seems to still be ongoing ； In terms of pressurization, Qin Neng Tianji Company is taking the lead in carrying out industrial demonstration projects, and Shanxi Coal Chemical Industry also conducted pressurization pilot tests. The entry of the American company SES into the domestic market disrupted the existing market landscape. Initially, SES was very active, but now, due to the economic crisis, its activities have almost come to a halt. Let’s wait and see what will happen in the future!
