摘要：Experiments of co-gasification of sludge and coal in supercritical water (SCW) are conducted to investigate any synergy between sludge and coal for enhancing coal gasification and hydrogen production. A thermal-catalytic reactor with continuous flow is employed to co-gasify Zhundong coal, sludge and their blends under a reactor with wall temperature of 650 degrees C-750 degrees C, pressure 26-29 MPa, and a residence time 1-30 min and sludge additive. The experimental results show that the produced gases consist mainly of H-2, CO2 and CH4, and the molar fraction of hydrogen reaches in excess of 60%; Nitrogen or sulfur is not detected in the produced gases, and contaminations with nitrogen is observed on the hydrogen yield and the gasification efficiency, and that the synergistic effect is mainly resulted from free radical reactions in SCW is proposed further. The present work indicates hydrogen production from co-gasification of sludge and coal in SCW is a promising new technology for clean energy conversion.
