Hydrogen-Rich Gas Production from Two-Stage Catalytic Pyrolysis of Pine Sawdust with Nano-NiO/Al2O3 Catalyst

Hydrogen production from biomass pyrolysis is economically and technologically attractive the perspectives of energy environment. The two-stage catalytic pine sawdust for hydrogen-rich gas investigated using nano-NiO/Al2O3 as catalyst at high temperatures. influences residence time (0–30 s) temperature (500–800 °C) on performance are examined in distribution products, composition, properties. results show that increasing decreased solid liquid products but increased products. Longer times could promote tar cracking gas-phase conversion reactions improve syngas yield, H2/CO ratio, carbon conversion. nano-NiO/A12O3 exhibits excellent activity removal, with a rate 93% 800 °C. significantly H2 CO yields by enhancing decomposition between CO2 CH4. increases dry yield decreases ratio low heating value.
