Hybrid-functional material for sorption-enhanced hydrogen-rich syngas production from biomass: Effect of material preparation process

Pyrolysis of waste biomass sawdust coupled with sorption-enhanced catalytic steam reforming the pyrolysis gases has been investigated using a novel Ni–CaO–Ca2SiO4 hybrid-functional material for enhanced hydrogen production. Using hybrid stabilized materials integrated sorption and catalysis functions overcomes thermodynamic constraint reaction equilibrium. The was prepared under different catalyst drying methods to determine influence on yield. In addition, process parameters water injection rate, temperature were optimize process. results showed that presence significantly improved yield volume fraction syngas. spray-dried shown be most effective in terms H2 purity syngas owing its relatively high stability higher surface area. spray gave highest 25.75 mmol gbiomass?1 eight times than material-free test at 850 °C rate 5 mL h?1. Furthermore, (H2 CO) also achieved these conditions, where optimal calorific value total gaseous products 10.63 kJ m?3.
