Design and construction of a sampling system that can collect PM10, PM2.5 and PM1 samples simultaneously from atmosphere
Ateş, Ömer; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2019)
In this study, a particulate matter (PM) sampling system that can collect PM10 (particulate matter with diameter of less than 10 μm), PM2.5 and PM1 samples simultaneously with a single pump on separate filters was constructed and validated. The sampler consisted of a F&J Specialty DF-1E carbon vane vacuum pump, with a flowrate of 115 L/min, and 3 channels connected to the pump through a manifold. Each channel had a cyclone, a filter holder of 47 mm diameter, a micro-orifice (critical orifice) for velocity c...

Investigation of passive sampling of no2 and o3 in ambient air and determination of the effects of meteorological parameters to the uptake rate
Bayındır, Elif; Tuncel, Semra G.; Department of Chemistry (2008)
In this study NO2 and O3 gases which are the secondary pollutants in ambient air were sampled with designed passive tubes. The collected samples were extracted for UV-VIS spectrometric analysis. NO2 gases were converted to NO2- ions by extracting with water and then this solution was colored with Saltzman reagent (5:1 sulfanilamide and N-(1 naphthly)-ethlyene-diamine dihydrochloride). Then the absorbance of the solution was measured at 537 nm. O3 was extracted with 3-metyl-2-benzothiazolinone hydrozone hydr...
CO2 hydrogenation to methanol over supported copper and gallium based catalysts at the atmospheric pressure
Osmanağa, Sezer; İpek Torun, Bahar; Önal, Işık; Department of Chemical Engineering (2022-8)
The continuous increase of the CO2 concentration in the atmosphere has been negatively impacting the environment, due to its contribution in the global warming. Hence, it is necessary for the current CO2 valorization techniques to advance in order to make use of CO2. A possible technique is the CO2 hydrogenation to methanol and DME. The process of CO2 hydrogenation to methanol has been taking place in industry for about a century. However, due to the thermodynamic limitation imposed by the reaction stoichio...
