Carbon dioxide adsorption isotherms have been computed for the Metal-Organic Framework (MOF) Fe2(dobdc), where dobdc4− = 2,5-dioxido-1,4-benzenedicarboxylate. A force field derived from quantummechanical calculations has been used to model adsorption isotherms within a MOF based on a parameterization scheme. Restricted Open-shell Møller-Plesset second-order perturbation theory (ROMP2) calculati...

As part of our efforts to model enhanced coalbed methane recovery and CO2 sequestration in coalbeds, we have investigated the pure adsorption isotherm behavior of five dry coals namely, Illinois #6, Wyodak sub-bituminous, Pocahontas, Beulah Zap, and Upper Freeport coal. Using a volumetric technique, isotherms of pure methane, nitrogen, CO2 and ethane were measured at a temperature of 328.15 K (...

The adsorption behaviour of Methyl violet and Auramine yellow from aqueous solution onto Stishovite clay was investigated as a function of parameters such as initial dye concentration, contact time, p and temperature. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. Adsorption followed pseudo-second order model. The experimental data fitted well ...

The equilibrium moisture content of red beetroot has been studied and the corresponding sorption- desorption curves have obtained at temperature 20°C. strain measurement method used to establish sorption curves. Analytical dependence describing also derived. Values contents for temperatures higher than 20°C by Pass Slepchenko’s method. results are presented in graphical table form.
