Abstract:
Hydrogen, considered as 21 century energy, got more attention in the recent years. In this paper a new approach of co-steam-reforming of biomass and crude glycerin for hydrogen production has been primarily provided. Experiments were conducted in a fixed-bed reactor (0.55 m long, 0.047 m DN), packed with 20 g catalyst (Ni/CaO/Al2O3 as the reforming catalyst), and some Calcined dolomite in the furnace to absorb CO2. All the experiments were taken at the glycerin/biomass weight ratio of 1:9, otherwise noted. Moreover, the effect of four running parameters (pressure, temperature, Ca/C and H2O/C) on the gas mole and mole fraction were explored. From the experiments, the conclusion can be made that co-steam-reforming of biomass and crude glycerin for hydrogen production is a feasible approach. Four running parameters have different effects on the gas mole and mole fraction: higher temperature do favor of the H2 mole but will decrease its mole fraction. Thus, in the co-steam-reforming experiment 700-750 ., the H2 mole is at the best value; Higher pressure also do favor of the H2, considering that the pressure of 0.6-1.1 M Pa can satisfy demand. High ratio of H2O/C makes the H2 mole and mole fraction with an obvious increase. When the ratio of Ca/C is higher than 1, the increasing of Ca/C will do no effects on the gas.
