Abstract

The coal–biomass mixed char co-gasification with H2O in the presence of H2was investigated under atmospheric conditions using a tube furnace and gas analyzer. Various partial pressures of H2O and H2were tested within a temperature range of 825–900 °C. Bituminous coal, pineapple sawdust, and a mixture of these two having a mass ratio of 1:1 were used to prepare chars. Random pore model was utilized to explain the experimental results. The results demonstrated that the inhibition effect of H2on char-H2O gasification can be described using the Langmuir–Hinshelwood (L–H) equation. The inhibition effect on the mixture sample was more intense than on the pure samples. The L–H equation kinetic parameters were acquired and expressed in an Arrhenius equation form to determine the pre-exponential factor and activation energy.
