The co-gasification of low rank lignite and sorghum energy crop was investigated under low temperature conditions with supercritical water. The study evaluated the effects of water volume, blending ratios, catalysts, and feedstock concentrations on gasification efficiency, product distribution, and hydrogen yield. Synergistic effects were observed with a coal content of 25 wt% in the coal/biomass mixture, and increasing water volume, decreasing feedstock concentration, and using alkali metal catalysts significantly improved gasification efficiency and hydrogen yield.
Co-gasification of low rank lignite (can) with sorghum energy crop was investigated under low temperature conditions with supercritical water (773 K, 26.9 MPa). The effects of the water volume in the reactor, blending ratios of the coal/sorghum mixtures, the use of different catalysts, and the variation of feedstock concentrations on the gasification efficiency, product distribution, and hydrogen yields were evaluated. Synergistic effects were observed for both the gasification efficiency and the hydrogen yield with a coal content of 25 wt% in the coal/biomass mixture. Increasing the initial water volume, decreasing the feedstock concentration, and using the alkali metal catalysts Na2CO3 and K2CO3 significantly increased the gasification efficiency and the hydrogen yield. In experiments with CaO, almost all the carbon dioxide formed was isolated from the gas product during gasification, and the hydrogen yield was more than 70%. The liquid products were mainly composed of alkylphenols and their derivatives. (C) 2021 Published by Elsevier Ltd on behalf of Hydrogen Energy Publications LLC.
