Conventional O_(2)gasification for low-rank biomass/sludge conversion is prone to high CO_(2)concentrations in the syngas because of its high O content and low calorific value.This study establishes a synergistic oxidationreforming reaction route for the conversion of low-rank carbon-containing resources into high-quality syngas.The efficient oxidation-reforming reaction is based on the bifunctional catalyst NiO-Fe_(2)O_(3)/Al_(2)O_(3),which includes Fe_(2)O_(3) oxidation sites and NiO reforming sites.Hydrogen temperature-programmed reduction,together with X-ray diffraction and X-ray photoelectron spectroscopy experiments,demonstrated that the two functional active sites have strong interactions with the support,leading to efficient cooperation between the oxidation reaction and reforming reaction with regards to both the reaction sequence and C/H/O element balance.Syngas produced from biomass/sludge based on oxidation-reforming reactions has an extremely low CO_(2)concentration of approximately 3%,and the valid gas(CO,H_(2))concentration exceeds 95%.The valid gas yield of walnut shell reached 1452.9 mL/g,the total gas yield was 1507.2 mL/g,and the H_(2)/CO ratio was 1.02,which are all very close to the theoretical maximum values of 1553.1 mL/g and 1.01,respectively,demonstrating that the inherent CO_(2)/H_(2)O along with CH4/tar species were efficiently converted to H_(2)and CO through oxidation-reforming reactions.During a 60-cycle test,NiO-Fe_(2)O_(3)/Al_(2)O_(3) exhibited good redox stability. 展开更多
