Co2 Gasification Reactivity

The residue of Inner Mongolia lignite semi-coke by different final temperature hydrogenation system methane of CO2 gasification reactivity is studied by means of thermo gravimetric and X-Ray Diffraction method. The results show that, with the rise of hydrogasification temperature, the residue aromaticity fa increase, the residual carbon microcrystalline tend to graphitization, CO2 reactivity decrease and residue CO2 reaction temperature raise. The final hydrogenation temperature residue CO2 gasification reaction conversion rate curves similar and curve to temperature increase in the direction of movement.

The CO2 gasification of three coal chars were investigated for determining the gasification reactivity and the kinetic parameters. Experiments were conducted in a fluidized-bed reactor at temperature of 1173 k, 1273 k and 1373 k at atmospheric pressure. Gasification kinetic parameters of the samples were determined using Homogeneous model and shrinking-core model. It is found that the gasification reaction under chemical-reaction-rate control, the gasification reactivity of coal char are strongly dependent on the rank of coals and gasification temperature. Both models could describe CO2 gasification equally well, these kinetic values are comparable with the reported in the literature for the other chars under chemical control conditions.
