Enhanced coal bed methane recovery using gas injection can provide increased extraction depending on the characteristics of and that is used. Accurate prediction extent adsorption by are therefore important. Both experimental methods modeling have been used to assess its effects, including volumetric gravimetric techniques, as well Ono–Kondo model other numerical simulations. Thermodynamic para...

The effect of fuel composition on gasification process performance was investigated by performing mass and energy balances on a pre-pilot scale bubbling fluidized bed reactor fed with mixtures of plastic waste, wood, and coal. The fuels containing plastic waste produced less H2, CO, and CO2 and more light hydrocarbons than the fuels including biomass. The lower heating value (LHV) progressively...

Fracture flow of two-phase mixtures is particularly applicable to the coal mining and coal bed methane projects in Australia. A one-dimensional steady-state pseudo-two-phase flow model is proposed for fractured rock. The model considers free flow of a compressible mixture of air and water in an inclined planar fracture and is based upon the conservation of momentum and the “cubic” law. The flow...
