Component Characteristic of Lignite Semi-Coke Hydrogasification Residue

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.
