    • Abstract
  • Adsorption and desorpion characteristics of methane (CO 2、N 2),from the coal of Zhucun,in alternative electric field with different frequencies have been studied with volumetric method.The result shows that the adsorption property of coal to CO 2,N 2 still coincides with the Langmiur Equation,and the alternative electric field weakens the adsorption ability of coal to methane,decreases the constant b,but does not change the saturated adsorption volume a,being typical surface modification.
