Academician Liu Zhongmin and the research team led by Researcher Zhu Wenliang have developed a new, environmentally friendly process route (DMTE technology) – using coal-based syngas as raw material to produce ethanol through dimethyl ether carbonylation and hydrogenation. This route uses non-precious metal catalysts, is free from corrosion, and can directly produce anhydrous ethanol. On January 11, 2017, the world’s first industrial demonstration project for coal-based ethanol with an annual production capacity of 100,000 tons – utilizing technology covered by China’s own intellectual property rights – completed the entire production process ； On December 28, 2023, the world’s largest ethanol production facility began trial operations in Huaibei, Anhui, with an annual production capacity of 600,000 tons of anhydrous ethanol ； In 2024, the 250,000-ton/year ethanol plant of Xinjiang Tianye Huixiang New Materials Co., Ltd., which utilizes this technology, was put into operation successfully from the very first attempt. This technology, combined with ethanol dehydration to produce ethylene, can further yield high-quality polyvinyl chloride, and it holds promise for promoting the adoption of green processes in China’s polyvinyl chloride industry based on the calcium carbide-acetylene method. To date, DMTE technology has secured 16 licenses for its implementation; the total ethanol production capacity amounts to 4.95 million tons per year. Five units have been put into operation, resulting in an ethanol production capacity of 1.65 million tons.
