Abstract
Adsorption kinetics of hydrocarbon mixtures in activated carbon is studied in this paper. In particular, the non-isothermal effects on kinetics are studied, and we will show in this paper that many interesting phenomena are observed for particle temperature, partial pressure, and adsorbed concentration. The oscillation of particle temperature with time, the negative fractional uptake, the undershoot of heavier species in displacement and the undershoot of weaker species in desorption are among the interesting phenomena. The quarternary systems of nitrogen, ethane, propane and n-butane/activated carbon are applied to test the model presented in this work.
