Yanchang Petroleum will start up 500,000 t coal to fuel ethanol plant in September 2022

https://www.chinadaily.com.cn/a/202207/26/WS62df3ea0a310fd2b29e6e57b.html The technology used at the plant, which is located in Yulin, Shaanxi province, has been developed by the CAS Dalian Institute of Chemical Physics. It uses a highly stable bifunctional catalyst made up from copper-based metal oxides and  SAPO-34 type zeolites to convert syngas, a mixture of hydrogen and carbon monoxide, into dimethyl ether, […]

10,000-ton coal-acetic acid – MMA project commissioned in Xinjiang

https://www.cas.cn/syky/202208/t20220804_4843853.shtml A demonstration plant of a 10,000-ton coal-based methanol-acetic acid to methyl methacrylate (MMA) process was put into operation in Hami, Xinjiang. The technology was developed by the CAS Institute of Process Engineering and is a third route to produce MMA  besides the isobutylene oxidation method and the ethylene-syngas method. Methyl methacrylate (MMA) is an […]
