The results show that smaller height of reaction channel can shorten the time which reactants diffuse from channel to reaction surface, longer length of micro-channel can extend residence time of reactants on the catalyst surface, and consequently increase the methane conversion and hydrogen production. The pressure drop between inlet and outlet increases lineally with the increasing of length, while the height influences the pressure drop significantly when the height is less than 0.4 mm. Based on the overall consideration for the methane conversion and resistance characteristic generally, the suitable height of channel should be between 0.4 mm and 0.6 mm.
