    • Abstract
  • At the temperature of liquid nitrogen the N2 adsorption process and adsorptive volume of coal samples are measured under the gas saturated vapour-pressure.Using BET and BJH theoretical models the pore volume and area of coal are calculated.The test of CH4 isothermal adsorption of coal samples is also calculated.Based on results it is discussed that the relationship among pore volume,total specific surface and pore type,as well as the influence on coal adsorptive capacity.
