Adsorption and regeneration dynamic characteristics of methane and hydrogen binary system

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.
