Simulate and Analyze of Biomass Gasification in Supercritical Water

Abstract

On the basis of ASPEN PLUS-based Gibbs free energy minimization, a biomass gasification model was modified by the restricted equilibrium of the RGIBBS reactor and developed and used to simulate glucose. It is showed that the simulation result and experiment result fit well. In the process of pomace gasification in supercritical water, a sensitivity analysis with temperature and pressure is performed and the research of the gas heating value has been done. From the analysis result, without using catalyst, the temperature has influenced on the gas product most and the pressure has little effect on gas product.
