Abstract
The diffusive-kinetic model of porous carbon particles gasification is developed. The model considers the processes of heat and mass transfer both inside the porous particle and above it. Analysis of the model shows that heat and mass transfer have an influence to the gasification process to a marked degree. Gasification of carbon particle by carbon dioxide is impossible if particle temperature is lower about 850 K because concentration of carbon dioxide at the particle surface becomes lower than its equilibrium concentration. The rate of the carbon particle gasification is determined as a function of the porous particle internal surface area for different pressures and furnace temperatures.
