The competition between the H2O and CO2 for the active sites during gasification remains a controversial issue in the literature. In this study, the competition between the H2O and CO2 for the active sites during gasification of coal, biomass, and a mixture of coal and biomass using the Langmuir–Hinshelwood (L–H) kinetic parameters obtained in our previous two papers (Massoudi Farid et al., 2016,...
In this study, co-gasification of coal and biomass chars with CO2 in the presence of CO was investigated at three different temperatures: 850, 875, and 900°C. A coal–biomass (bituminous-pineapple sawdust) mixture with a mass ratio of 1:1 was used for devolatilization and co-gasification. Random pore model was employed to determine the kinetic coefficient from experimentally obtained carbon conversion...
The coal–biomass mixed char co-gasification with H2O in the presence of H2 was investigated under atmospheric conditions using a tube furnace and gas analyzer. Various partial pressures of H2O and H2 were 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...
