Tianshan News (Reporter Ma Yining Correspondent Wang Qianxi reported) Recently, the "Identipable Polyte Oxygen Round Delivery Beds, Xinjiang Yizhou Chemical Co., Ltd. and Zhongke Hefei Gel Chemical Technology Co., Ltd. were jointly completed by the Chinese Academy of Sciences. "High -alkali gas chemical synthetic gas technology" passed the appraisal of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation in Beijing. The appraisal committee agreed that the technology generally reached the international advanced level, reaching the international leading level in high alkaline gas, and has positive significance for Xinjiang's high -alkaline coal development and development of the local economy.

The picture shows the use of high -alkali gas chemical synthetic gas technology use devices of Xinjiang Yizhou Chemical Co., Ltd. Drawing

The forecast reserves with a reserves of 390 billion tons are the largest coal fields in my country, but the high -alkali coal in the coal field has the characteristics of poor viscosity, poor pulp, and high alkaline metal content. Essence

This technology takes Xinjiang Yandong Coal as the research object, and through technical innovation control of the temperature partition control, flow field and reaction regulation, the thermal recovery system of the residual heat recovery system, and the residual heat recovery system. The gasification efficiency, the overall energy efficiency of the system, and the reliability of the gasification furnace have been greatly improved, reducing the discharge of wastewater, and eliminating the pollution of tar and phenol -containing wastewater.

"This technology has a strong adaptability to the raw coal ash melting point, and the process is simple. You can use quasi -east high -alkali powder as raw materials and do not need to make powder. Gas and wastewater do not contain caramel and phenol. Chief engineer Yang Xiaoqin said.

As one of the key coal chemical enterprises in Xinjiang Junior East Economic and Technological Development Zone, Xinjiang Yizhou Chemical is mainly produced by producing synthetic ammonia, urea, melamine and other products. Since 2019, the company has upgraded the synthetic ammonia production line, has invested 380 million yuan, and built three newly -permeable oxygen -rich cyclic -fluidized bed gasification devices to replace the original 20 constant fixed -fixed beds. The company's self -produced high -alkali coal is made into qi for raw materials, producing synthetic ammonia, urea, melamine, etc., through continuous development and optimization of the past three years, the long -term operation of the device is achieved.

"Compared with the previous, the cost of producing ammonia using this technology is reduced by 400 yuan/ton, the annual economic benefits of 160 million yuan, and it can also reduce energy consumption of 95,000 tons of standard coal. The solid waste is 150,000 tons. Economic and social benefits are very significant. At present, this technology has obtained 5 national authorized invention patents and 2 practical new patents. "Yang Xiaoqin said.
