We used the SRK equation of state for the molar mass of the gas on a fixed bed with a height of 400 mm and an inner diameter of 10 mm. Finally, physical properties were determined using FTIR, XRD, FE-SEM, and BET. Statistical analysis showed that the signal-to-noise ratio between ...
H2S (2602 cm−1), CO2Fermi diad (1281 cm−1, 1384 cm−1), and N2(2326 cm−1), representing symmetric stretching vibrations (ν1) of the gas molecules. Weak intensity broad peak at 3013 cm−1is attributed to the ...
defined as the “test mixture” in the paper. The samples were obtained by withdrawing the H2S from a certified H2S gas cylinder (SAPIO technical gas, Milano, Italy) into Nalophan bags with a volume of 6 liters and a surface of 2580 cm2. ...
Nano-crystalline ZnO, with its advantages of quantum size effect and high surface/volume ratio [7], can effectively enhance the H2S capture at room temperature. Supporting ZnO on porous materials is a general approach to fabricate nanosized ZnO adsorbents [7], [8], [9], [10]. This is be...
The CH4/O2 molar ratio, temperature, pressure, and the gas hourly space velocity (GHSV) of the reactant gas equaled 2, 700 °C, 1 atm, and 7.32 × 104 mL gcat−1 h−1, respectively. The reactor was maintained at the desired temperature with an accuracy of ±1 °...
High gas concentrations can also be reached securely. The technique of synthetic fluid inclusions has been adapted to this procedure. This technique provides an in situ sampling of fluids during experiments. After experiments, mass balance of gaseous species can be calculated ...
The molar volume can be determined from the experimental density: Figure 5. Henry’s law constants of CO2 (a) and H2S (b) as a function of the fractional free volume for [doc]-based ionic liquids. Vm = Mr/ρ (8) where Mr is the relative molar mass of the IL....
A mixture of H2S/air (samples exposed in aerobic conditions) and H2S/Ar (samples exposed in anaerobic conditions) was fluxed into the box at a constant H2S partial pressure of 250 Pa, controlled by calibrated mass flow controllers (Alltech Digital Flow Check-HR) and gas mixing valves. H2S ...
