Abstract The increasing energy shortage and the dependence of economic development on energy provide important development opportunities for the development of fuel ethanol. As a clean energy source without S and ash, ethanol is one of the best fuels to replace gasoline. The economical and feasible syngas production ethanol technology used in the coal chemical enterprises will have the very good economic and social benefits. The reaction mechanism, process and progress of the production technology of fuel ethanol from coal to syngas by biofermentation were introduced, and the economy of the technulogy was analyzed. It is piunted out that the ethanol production technology is economical and feasible, but it is necessary to consider the late cost increase caused by the additional distillation or dehydration processes because of the low concentration of ethanol in the product.
