Abstract

In order to optimize the performance of an adsorption column, the adsorption and regeneration dynamic characteristics were studied for 20% methane and 80% hydrogen binary system on nonisothermal and nonadiabatic conditions. The adsorption dynamic characteristics were studied at various flow rates, 7.2 LPM to15.8 LPM, and at various adsorption pressures, 6 to 12 atm. Also, regeneration dynamic characteristics were studied at various purge rates, 1.5 to 3.5 LPM, and constant pressure, 1.2 atm. Nonisothermal and nonadiabatic models, considering linear driving force model and Langmuir-Freundlich adsorption isotherm model, were considered to compare between prediction and experimental data.
