The coal gasification process of a slurry feed type, entrained-flow coal gasifier was numerically predicted in this paper. By dividing the complicated coal gasification process into several simplified stages such as slurry evaporation, coal devolatilization and two-phase reactions coupled with turbulent ...
In this study, a designed coal seam water injection simulation experimental device was utilized to conduct dynamic water injection experiments on coal samples at different adsorption equilibrium pressures, analyzing the gas desorption law under dynamic water injection, as well as the role of water ...

The development trend of coal chemical industry is to develop clean coal conversion process,so as to reducing the emission of pollutants.In currently,there have been many studies on the emission of pollutants such as CO2,NOx,SOx,but the ones on PAHs (Polycyclic Aromatic Hydrocarbons) are not en...
Entrained flow gasification using liquid slag discharge is the most promising technology for utilizing coal in the chemical industry (Shi et al., 2018). During the gasification process, the inorganic matter transforms into molten slag, adhering to the inner wall of the gasifier. Then, the slag ...
Precious metal catalysts have been considered for both coal combustion and gasification processes, and as such, findings associated with both applications will be reviewed and discussed.
