The direct production of olefins from synthesis gas is about to be industrialized!

Recently, the pilot project of “Coal-to-Syngas Direct Production of Low-Carbon Olefins” jointly implemented by Dalian Institute of Chemical Physics, Chinese Academy of Sciences and Yanchang Petroleum Group .

This technology is based on the original basic research results of OX-ZEO on "high selective conversion of syngas to light olefins" obtained by the team led by academician Bao Xinhe and researcher Pan Xiulian from the Dalian Institute of Chemistry (published in the American "Science" magazine in 2016, that year Rated as one of the top ten scientific advances in China), this achievement abandoned the traditional high water consumption and high energy consumption of water-gas shift hydrogen production process and intermediate products (such as methanol and dimethyl ether, e.

In recent years, in order to alleviate the dependence on petroleum resources and promote the efficient utilization of coal and natural gas resources, the research on olefin production technology at home and abroad mainly focuses on non-petroleum routes, that is, the use of coal or natural gas resources to directly or indirectly prepare olefi.

The synthesis gas directly produces olefins or is based on Fischer-Tropsch to Olefins (FTO) or relies on bifunctional oxide-molecular sieve catalys.
