Abstract

This research provides a perspective on sludge-to-energy using sewage sludge (SS) and industrial wastewater sludge (IS) co-gasification in a pilot-scale fluidized bed gasifier with temperature controlled at (600–800 °C) using IS addition ratio (0%–60%), and steam-to-biomass ratio (S/B) (0–1.0). The experimental results show that the increase in thermal reaction activity occurred in concordance with the increase in the IS addition. The explanation for such phenomena is that relatively high catalytic Fe/Mn content in industrial wastewater sludge could lower the activation energy. Hydrogen production was increased from 9.1% to 11.94% with an increase in industrial wastewater sludge ratios from 0% to 60%. The produced gas heating value ranged from 4.84 MJ/Nm3 to 5.11 MJ/Nm3, which was coupled with the cold gas efficiency (CGE) ranging from 33.91% to 36.15%. Enhanced hydrogen production in sewage sludge and industrial wastewater sludge co-gasification is investigated in this study.
