The authors try to reveal the dominant chemical reactions and the optimum conditions, supposing the design of ethanol steam-reforming reactors for hydrogen production. Experiments are conducted for Cu/ZnO/Al_2O_3 catalyst. Using a household-use-scale reactor with well-controlled temperature distributions, we specify the effect of liquid-hourly space velocity LHSV upon the ethanol conversion X_<C2H5OH> and upon various concentrations. Furthermore, we compare experimental results with chemical-equilibrium theories. As a result, the obtained concentrations suggest that the dominant chemical reactions at LHSV < 0.2h^<-1> are different from those at LHSV > 0.2h^<-1>.
