As a clean and renewable energy, ethanol enters people's vision. As one of the representatives of renewable liquid fuel, fuel ethanol can supplement fossil fuel resources, and has attracted the attention of all countries. In this paper, the development status of fuel ethanol is introduced; the raw materials and the preparation process are explained; the advantages and disadvantages of using different raw materials are expounded; the theoretical differences of different processes and the difficulty of realizing mass production are explored. The objective factors that make the fuel ethanol preparation industry develop better and faster are analyzed in the paper.
