On December 26, Henan Liyuan Coal and Coke Group Co.
, Ltd.
's 200,000 tons/year coke oven gas ethanol project opened the whole process at one time, producing anhydrous ethanol products
with a purity of 99.
8%.
The project adopts the dimethyl ether carbonylation hydrogenation to ethanol (DMTE) technology with independent intellectual property rights of Yanchang Zhongke Company, which is a beneficial attempt to utilize coke oven tail gas resources in Liyuan Group's 1.
28 million tons/year coking project, and is the world's first industrial demonstration project
for the production of absolute ethanol by coke oven gas chemical synthesis.
The project uses coke oven gas instead of traditional grain fermentation to produce ethanol, which can save 600,000 tons
of grain per year.
At the same time, the project has changed the utilization mode of traditional coke oven gas combustion power generation, and efficiently converted into high value-added ethanol products through the green process of coke oven gas, which can reduce carbon dioxide emissions by about 190,000 tons
per year.
The completion and production of this project further verifies the advanced and mature technology of DMTE patented technology of Yanchang Zhongke Company
.
