Temperature dependences of parameters n and E are calculated according to the adsorption equation of Dubinin-Astakhov for methane adsorption on eight active carbons in the range of supercritical temperatures of 170-340 K and pressures of 0-20 MPa. At temperatures above similar to 240 K, characteristic adsorption energy E of methane grows linearly at an increase in temperature. The temperature coefficients of characteristic energy of methane adsorption on active carbon tend to decrease at an increase in standard characteristic adsorption energy E (0). The average value of parameter < n > for the studied adsorbents tends to grow at an increase in standard characteristic adsorption energy E (0).
