Abstract：

Based on the theory and method of volume correction for methane isothermal adsorption test,the volume correction form ulation of multi- component gas adsorption is presented.In addition,the density of absorbed phase of multi- component is discussed and calculated.Through the example,it is shown that the relative error of adsorbed gas content of multi- component is lower than that of methane.
