Hydrogen Production From Crude Bio-oil and Biomass Char by Electrochemical Catalytic Reforming

We reports an efficient approach for production of hydrogen from crude bio-oil and biomass char in the dual fixed-bed system by using the electrochemical catalytic reforming method. The maximal absolute hydrogen yield reached 110.9 g H(2)/kg dry biomass. The product gas was a mixed gas containing 72%H(2), 26%CO(2), 1.9%CO, and a trace amount of CH(4). It was observed that adding biomass char (a by-product of pyrolysis of biomass) could remarkably increase the absolute H(2) yield (about 20%-50%). The higher reforming temperature could enhance the steam reforming reaction of organic compounds in crude bio-oil and the reaction of CO and H(2)O. In addition, the CuZn-Al(2)O(3) catalyst in the water-gas shift bed could also increase the absolute H(2) yield via shifting CO to CO(2).
