  • Influence of steam on ignition of Victorian brown coal ...

    It produced a highly concentrated flammable gas mixture of CO and H2 in coal particle cloud, which in turn accelerated the homogenous ignition of volatiles. This promotion effect is the most dominant for brown coal, because its volatile is rich in light hydrocarbons including gaseous CO that can readily react with the external steam via water ...

  • Influence of Coal Particle Size on Coal Adsorption and ...

    Abstract Accurate testing coal isotherm can play a significant role in the areas of coal seam gas drainage, outburst control, CO 2 geo-sequestration, coalbed methane (CBM) and enhanced coalbed methane recovery (ECBM) etc. The effect of particle size on the CO 2 and CH 4 sorption capacity of bituminous coal from Illawarra, Australia was investigated at 35°C and at pressure up to 4 MPa.
