Abstract As one of the widely used chemicals, Ethanol is also an important additive for clean energy. With the comprehensive promotion of ethanol gasoline in recent years, the demand for ethanol is increasing year by year, and the market prospect for ethanol is huge. The current development status of the synthesis process of ethanol was described. The biological fermentation, petroleum-based ethylene hydration and coal-based syngas synthesis were introduced mainly and the technical status of these three synthesis processes was reviewed. Combined with the energy structure characteristics of ‘more coal, less oil and less gas’ in China, the technology of ethanol production from coal-based syngas will become an important part of Chinese energy and chemical industry. With the continuous optimization and improvement of coal-based ethanol production technology, it has great significance to promote the development of energy cleanness in China.
