Table 1 Performance of sorbents for removing mercury from a gas mixture Sorbent AC s Duncan A1 + A2 3.38 0.465 A A2 3.34 0.444 A C1 2.93 0.508 AB A1 2.52 0.360 B C2 1.91 0.435 C Gas flow = 200 mL min−1; mercury concentration in the gas mixture = 6.35 pg L−1; experiment time = 3 min. A1 and A2 columns contain Au and Pt, respectively.
Scanning electron microscopy (SEM) shows a highly porous structure of the SnO2 gas sensor operated by ac voltage.
We explain the excellent sensitivity of the SnO2 gas sensor operated by ac voltage in terms of a simple grain dispersion model taking into account the highly porous architecture of the sensing film, which increases adsorption centers.
Recent work on the low heat input and high deposition rate welding process of pulsed alternating current gas metal arc welding (AC-GMAW) has paved the way for the implementation of a cost effective solution for thick plate welding.
A total energy system (TES) incorporating a solid oxide fuel cell (SOFC) and an exhaust gas driven absorption chiller (AC) is presented to provide power, cooling and/or heating simultaneously.
In order to purify argon from the extracted gases, three SORB-AC getter pumps (NP10) are used.
Although the overall values of EF5 positive areas were relatively low, the total median EF5 positive area was significantly greater in tumours from mice exposed to 6 weeks of AH than AC gassing.
We have developed a high-safety and low-cost method for methane gas storage on activated carbons (ACs) prepared from biomass waste, to enable methane gas to be used effectively and safely.
In terms of ADS planning, expansion of substations, CCHP, gas heating boiler (GHB) and AC are all considered as investment options.
Tungsten oxides dispersed on Al2O3, ZrO2, and SiO2 supports were investigated for catalytic dehydration of glycerol (GL) to form acrolein (AC) in the gas phase at 315 °C with aqueous GL (GL concentration: 36.2 wt% or 10 mol%, molar GL/H2O = 1/9) as the feed (GHSVGL = 400 h−1).
AC does not enhance any gas phase activity while addition of AC in AP increased the LPDL of AP and reduced the burn rate.
