Adsorption of methane on an MOF-199 organometallic framework structure at high pressures in the range of supercritical temperatures

Аннотация

Synthesis of an adsorbent based on an organometallic framework of the MOF-199 type is performed. The Dubinin–Radushkevich equation is used to calculate the structure–energy characteristics of adsorbents on the basis of data on nitrogen adsorption at 77 K as per benzene. Methane adsorption is studied on the obtained MOF-199 adsorbent, and adsorption isosteres are plotted. The capacitive characteristics of the adsorption system for methane storage with the synthesized adsorbent are determined. Differential molar isosteric and integral adsorption heats are calculated.
