Biomass gasification in supercritical water with partial oxidation

Abstract

Effect of partial oxidation on characteristics of biomass supercritical water gasification was studied using 0.6 M glucose, a model compound of biomass, and cabbage slurry in temperature range of 673-873 K at 25 MPa. Partial oxidation was efficient for supercritical water gasification of both glucose and cabbage slurry. The improvement of gasification efficiency was accompanied with higher yield of both hydrogen and carbon monoxide. The effect is clear at higher temperature. Proper amount of oxidant addition needs to be decided.
