Study on coal and gas outburst by thermodynamic desorption threshold

Meikuang Anquan, 2023
The desorption process of coal is interpreted from the perspective of thermodynamics. The four pending parameters of temperature-pressure-adsorption equation (TPAE) were obtained by using the measured series isothermal adsorption data of high-order ...

Isosteric Heats of Adsorption of N2O and NO on Natural Zeolites

Journal of the Mexican Chemical Society, 2019
We studied the capacities of three natural zeolites to adsorb N2O or NO using a glass high-vacuum volumetric system that permitted characterization of the energetics of the adsorption process. Adsorption equilibrium data were analyzed using the classical Freundlich equation and the Dual–Langmuir model. We employed the Clausius–Clapeyron relationship to

Adsorption of selected GHG on metal-organic frameworks in the context of accompanying thermal effects [PDF]

Archives of Environmental Protection
Thermal effects accompanying gas sorption on micro- and mesoporous materials provide unique insights into the type, course, and efficiency of sorption. In this study, metal-organic frameworks (MOFs) with different topologies and chemical structures were ...

Study on heat adsorption based on the experiment of coal adsorption of methane by using the weight method

Journal of Natural Gas Geoscience, 2021
The study of heat adsorption plays an important role in understanding the mechanism of methane adsorption from coal. The gravimetric method was used to conduct 303 K, 308 K, and 313 K isotherm adsorption experiments on two sets of coal samples; the ...

MOISTURE ADSORPTION ISOTHERMS AND ADSORPTION ISOSTERIC HEAT OF DRY GROUND MEAT

Gıda, 2022
Dry ground meat is a cooked meat product. It is a popular meat product in Central Anatolian Region of Turkey. Calf plate or flank meats and intermuscular fats are used in the production of dry ground meat. In this study, sorption isotherms were determined using nine different salt solutions (0.1-0.9 aw) having different relative humidity values at 5 ...

Simulation study on adsorption characteristics of lignite to mine gas

AIP Advances, 2022
This study aims at investigating the adsorption mechanism of CO2, CH4, CO, and N2 mine gases and oxygen-containing functional groups in lignite. Thus, density functional theory and grand canonical Monte Carlo simulation methods were used to determine the

Isosteric Heats of Gas and Liquid Adsorption

, 2016
The heat of adsorption is an indicator of the strength of the interaction between an adsorbate and a solid adsorbent. This parameter can be determined from the heat released in calorimetric experiments or from the analysis of adsorption isotherms at ...
