This study evaluated the catalytic steam gasification of furniture waste to enhance biohydrogen production, with the Ni/CeO2-ZrO2 catalyst showing the best catalytic activity at 800 degrees Celsius due to its small nickel crystal size, finely dispersed nickel on the catalyst surface, and presence of Ce1-xZrxO2-5 solid solution.
Present study evaluated the catalytic steam gasification of furniture waste to enhance the biohydrogen production. To do this, 10 wt% nickel loaded catalysts on the variety of supports (Al2O3, CeO2, CeO2-La2O3, and CeO2-ZrO2) were prepared by the novel solvent deficient method. The hydrogen selectivity (vol%) order of the catalysts was achieved as Ni/ CeO2-ZrO2>Ni/CeO2>Ni/Al(2)O(3)xNi/CeO2-La2O3. The best catalytic activity of Ni/CeO2-ZrO2 catalyst (-82 vol % H-2 at 800 degrees C) was ascribed to the smaller size of nickel crystals, finely dispersed Ni on the catalyst surface, and Ce1-xZrxO2-5 solid solution. The role of Ce1-xZrxO2-5 solid solution in Ni/CeO2-ZrO2 catalyst was observed as bi-functional; acceleration of water-gas-shift and oxidation of carbon reaction. The high resistance of Ni/CeO2-ZrO2 towards the coke formation showed its potential to establish a cost-effective commercial scale biomass steam gasification process. This study is expected to provide a promising solution for the disposal of furniture wastes for production of clean energy (biohydrogen). (C) 2020 Hydrogen Energy Publications LLC.
