摘要

This short communication reports the results of an experimental study that is an expansion of two previous studies (Jeong et al., 2014, 2015). In this study, mixtures of coal and biomass with different mass ratios were co-gasified with CO2 or H2O. Five different partial pressure conditions between 0.2 and 0.6 bar were tested for both gasifying agents. Random pore model was used to interpret the carbon conversion data. Pre-exponential factors and reaction orders of CO2 and H2O gasifications were determined using the Arrhenius equation and activation energies obtained in the two previous studies.
