Nonisothermal effects on the adsorption kinetics of ethane and propane in activated carbon are described for both single and binary systems. A heterogeneous macropore, surface and micropore diffusion model recently proposed by Hu and Do (1993) describes the mass-transfer rate processes of gases in a heterogeneous microporous bidispersed particle. The model is extended to cover nonisothermal effects by taking into account the energy balance around the particle system. Experimental uptake data of ethane and propane in Ajax activated carbon previously collected in our laboratory (Hu et al., 1993; Hu and Do, 1993) satisfy the isothermal criterion
