Web8 nov. 2016 · Abstract. The adsorption behaviors and structural features of methane in quartz nanopores were investigated using GCMC and MD methods, and the influences of the different pore sizes, temperatures, and water content on methane adsorption on quartz are discussed herein. The results show that the isosteric heats of methane decreased … WebMethane storage and release in ZIF-8 slurries and fixed beds were investigated. The ZIF-8 retained 98.62%, while the activated carbon lost 62.17% of their adsorption capacities in slurry. In ZIF-8 fixed beds, methane storage density of 127.41 V/Vbed was acquired, while the gas loss during depressurization accounted for 21.50% of the gas uptake. Web2 jul. 2015 · We investigate methane adsorption in a large library of metal-organic frameworks (MOFs) using four versions of classical density functional theory (DFT) and calibrate the theoretical predictions with extensive simulation data for total gas uptake and delivery capacity. fake ultrasound free
