Investigation of non-isothermal and isothermal gasification process of coal char using different kinetic model

International Journal of Mining Science and Technology, 2015
Isothermal and non-isothermal gasification kinetics of coal char were investigated by using thermogravimetric analysis (TGA) in CO2 atmosphere, and the experimental data were interpreted with the aids of random pore model (RPM), unreacted shrinking core ...
