Experimental adsorption data of difluoromethane (HFC-32) on activated carbon in powder (ACP) and fiber
(ACF) forms over a range of (25 to 75)°C and pressures up to 1400 kPa are reported. The data are fitted to Tóth and Dubinin− Astakhov isotherm equations. Adsorbed phase volume is derived from the data. Isosteric heats of adsorption are extracted, and their dependence on relative loading and relative pressure is analyzed.
