Supposing the design of household-use-scale ethanol-steam-reforming reactors, the authors conduct experiments with Cu/Zn0/Al203 catalyst More specifically, the authors investigate the influences of liquid-hourly space velocity LHSV upon concentrations such as C_<H2> C_<CO2>, C_<CO> and C_<CH4> and the influence of LHSV upon the ethanol conversion X_<C2H5OH>, in a wide range of LHSV at several S/C's and at several T_R's To conclude, all the concentrations are close to the theory of Shinoki et al. (2011) except for the case at low T_R (= 520 K) and high LHSV (>0.6 h^<-1>) To settle the inconsistency of this exceptional case, the authors propose a new theory using some chemical reactions related with acetaldehyde CH_3CHO By introducing the chemical-equilibrium performance measure a into this new theory, we can settle the inconsistency Furthermore, the authors discuss the influences of S/C and T_R in addition to LHSV
