Modeling of gasification process of Indian coal inperspective of underground coal gasification (UCG)

In the present study, the steam gasification of Indian coal and its demineralized coal were investigated in a specially designed fixed-bed reactor, to determine the intrinsic kinetics parameters with optimum operating temperature and partial pressures of steam in the perspective of underground coal gasification (UCG). The gasification reactivity of a chosen coal was higher compared to the demineralized coal and the reason could be mineral content of ash present in the coal. A one-dimensional unsteady kinetic model was developed for the steam gasification process
in a fixed-bed reactor. The intrinsic kinetic parameters for steam gasification and water–gas shift reaction are estimated by fitting the developed models with the experimental data.
