On thermodynamics of methane+carbonaceous materials adsorption

An experimental investigation into the effects of zeolites on the formation of methane hydrates

“…Quartz glass windows (diameter, 30 mm) were installed at the front and rear sides of the reactor (20) to facilitate observations when reaction takes place. A diaphragm valve (16) was installed to supply the gases while maintaining a constant pressure in the reactor. For high-precision measurements, two metering valves were installed between the supply vessel (10) and the diaphragm valve (16) to control the flow rate.…”

“…A diaphragm valve (16) was installed to supply the gases while maintaining a constant pressure in the reactor. For high-precision measurements, two metering valves were installed between the supply vessel (10) and the diaphragm valve (16) to control the flow rate. As the gas in the reactor was consumed to form hydrates, additional gas was supplied automatically from the supply vessel while the pressure in the reactor was kept constant using the diaphragm valve.…”

Comparative Study of Textural Characteristics on Methane Adsorption for Carbon Spheres Produced by CO2Activation

“…In addition, the pore structure offers the potential to adjust the thermodynamic properties of adsorption. Herein, an effective approach for investigating the methane adsorption capacity and tuning the thermodynamics of adsorption is by controlling the pore structure [2,10,36,37]. However, the pore structure of ACs is highly dependent on the activation process, among which thermal or physical activation of ACs has been widely used.…”

Adsorption kinetics of propane on energetically heterogeneous activated carbon

“…Further, the thermal expansion was assumed to be independent of the adsorbate species, and the mean value of gases (a e ¼ 2.5 Â 10 À3 K À1 ) was used in the numerical calculation. The utilization of this equation accounts for the adsorbed phase volume correction has successfully been used in previous works resulting in an improved fit [11,12] with relative ease. A pressure controller ER3000 is used to set the chamber pressure, and water from the water bath enters the jacket to maintain the desired temperature.…”
