Gas Permeability Model for Porous Materials from Underground Coal Gasification Technology

Underground coal gasification (UCG) technology converts deep resources into synthesis gas for use in the production of electricity, fuels and chemicals. This study provides an overview systematic methods situ process. Furthermore, model porous structure has been presented movement taking place carbon matrix—which is part bed—has described. The experimental tests were carried out with air forced through nozzle form a stream spreading many directions bed under bubbling conditions. flow resistance coefficient was determined as function Reynolds number relation to diameter nozzle. proprietary calculation compared models researchers, indicating characteristic trend decrease increase number. novelty determination permeability characteristics char (carbonizate) melted waste rock situ, account tortuosity factors irregularly shaped solid.
