Pore network geometries are crucial to oxygen concentration, gas diffusivity, water location and water movement.
The effect CO2 concentration on soot concentration, gas temperature, carbon conversion, etc., is numerically investigated by changing the inlet concentration of CO2 at a constant O2 ratio (=0.528).
When the gas flow resistance between the surface borehole and the gob decreased, a lot of low concentration gas from the gob was extracted by the borehole.
The effect of O2 ratio on soot concentration, gas temperature, carbon conversion, etc., is numerically investigated under CO2-rich gasification condition (CO2 concentration = 14 wt%).
The CO2 concentration of the seawater in the aquariums was controlled by aerating the FSW with air (control) or high CO2 concentration gas (1000 ppm).
The seawater of each aquarium was exchanged once per day with pre-treated seawater aerated with air (control) or high CO2 concentration gas (1000 ppm).
Prior to each measure, the system was calibrated for O2 concentration, gas volume and delay, according to the manufacturer's recommendations.
This means that if performed precisely, such structures may also be good candidates for preconcentrating purposes, especially for low-concentration gases.
To illustrate the advantage of our growth method, CNWs deliberately grown between metal electrodes were used for detection of low-concentration gases including NO2 and NH3, thereby demonstrating a one-step gas sensor fabrication process.
At the Geoservices mud logging laboratory, total gas concentration and gas composition were determined separately using two individual gas chromatographs.
