The hottest new catalyst and supporting facilities

The Chinese Academy of Sciences has made a breakthrough in the "new catalyst and supporting process technology for the production of low-carbon mixed alcohols from syngas"

the pilot plant has completed more than 1200 hours of successful operation.

after years of research, the Shanxi Institute of coal chemistry of the Chinese Academy of Sciences has made a breakthrough in the "new catalyst and supporting process technology for the production of low-carbon mixed alcohols from syngas" and completed more than 1200 hours of pilot plant stable operation. This technology uses a new copper iron based catalyst, at a temperature of ℃ and a pressure of 4 Under the mild reaction conditions of 0mpa and space velocity H-1, the conversion of CO is 80%, the selectivity of c2+ higher alcohols is 50%, and the space-time yield of low-carbon mixed alcohols is 0.23kg/k zigzag gcat h. All process performance indicators have reached the leading level

this project is a high-efficiency syngas conversion technology that replaces noble metal catalysis in the field of clean energy. It has the characteristics of low catalyst cost, high atomic economy and strong operational feasibility. With the support of the 973 project of the Ministry of science and technology, the major project of the Foundation Commission, Wu Guanghui, deputy general manager of Henan coal and chemical industry group and COMAC of shell oil company of the Netherlands, the R & D team abandoned the traditional high-temperature and high-pressure harsh synthesis reaction conditions and the use of high-cost processes of precious metals, and directed the development of the scope of application: the technical route of producing high value-added chemical mixed alcohols and fuel additives from syngas, under low reaction pressure and temperature, Higher alcohol yield and c2+ alcohol selectivity can be obtained to realize low-carbon and efficient conversion of syngas. At present, Shanxi Coal Chemical Institute has applied for 7 national invention patents

the successful operation of this pilot plant has laid a solid foundation for the 10000 ton industrial demonstration of syngas to low carbon mixed alcohol, and has the industrial application prospect of replacing methanol process technology. Under the background of increasingly tight crude oil supply and the continuous downturn of methanol alternative fuel market in recent years, this technology is expected to become an important way to reduce oil dependence and avoid methanol market risks
