Abstract: The experimental evidences of the intermediates existed in ethanol steam reforming reaction are summarized. The relevant mechanism discussions from the literature are introduced in detail. The possible reaction paths in the process of hydrogen production from ethanol steam reforming are generalized. That catalyst constitution, crystal lattice structure, surface acid and alkaline，redox property have significant influences on reaction mechanisms and that ratio of water than ethanol, temperature, pressure and other reaction conditions have effects on products selectivity and equilibrium concentration are pointed out. The research trends of quantifying surface property and crystal structure parameters to deeply studying reaction mechanism are prospected.

Key words: ethanol, hydrogen production, reforming, reaction mechanism
