Pyrolysis of Biomass in Molten KOH-NaOH to Hydrogen Rich Gas

Abstract Pyrolysis of rice straw in molten alkali to produce hydrogen rich gas has been studied in a self designed reactor. The effects of molten NaOH, molten KOH and molten KOH-NaOH with different K/Na ratio, on products distribution, gas product yield and H₂ content in gas have been investigated. The results show that molten KOH is more favorable than molten NaOH to increase H₂ content in gas product. 87.4% H₂ content in gas product and H₂yield of 0.7 L/gbiomass have been reached for pyrolysis of rice straw in molten KOH under atmospheric pressure, 450 ℃ and 100 L/h of N2 flow rate.
