Concentrations and emission rates of sixteen trace elements in emitted PM during heating soybean oil using three types of pans, including Teflon, granitium, and cast-iron, were investigated. Statistically significant decreases in Mn and Co emission rates were observed when the oil was heated in the cast-iron pan compared to Teflon and granitium pans. Among the released trace elements, Ni, Ba, Zn, and Cr had more contribution to the emission rate. The concentrations of Fe in the emitted PM1 were found to be higher when cast-iron pan (8.49 +/- 3.35 mu g/m(3)) was utilized compared to Teflon (8.05 +/- 2.27 mu g/m(3)) and granitium (7.45 +/- 1.38 mu g/m(3)). However, these increases were statistically insignificant. The results of our study support the hypothesis that the trace elements translocate from cooking pans into the heated oil and subsequently to the particulate phase. This translocation creates a new inhalation exposure route to trace elements in indoor environments.

Investigation of productivity of heavy oil carbonate reservoirs and oil shales using electrical heating methods Hasçakır, Berna; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2008) The recovery characteristics of Bolu-Himmetoglu, Bolu-Hatıldag, Kütahya- Seyitömer, and Nigde-Ulukısla oil shale samples and Batı Raman, Çamurlu, and Garzan crude oil samples were tested experimentally using retort and microwave heating techniques. Many parameters like heating time, porosity, water saturation were studied. To enhance the efficiency of the processes three different iron powders (i.e.; Fe, Fe2O3, and FeCl3) were added to the samples and the doses of the iron powders were optimized. While crud...
A nonintrusive diagnostics technique for flame soot based on near-infrared emission spectrometry Ayrancı Kılınç, Işıl; Selçuk, Nevin; Department of Chemical Engineering (2007) A novel nonintrusive soot diagnostics methodology was developed, validated and applied for in-situ determination of temperature, volume fraction and refractive index of soot aggregates formed inside flames by using near-infrared emission spectrometry. Research was conducted in three main parts, first one addressing development and validation of a comprehensive "direct" model for simulation of line-of-sight radiative emission from axisymmetric sooty flames by coupling sub-models for radiative transfer, radia...
The synthesis and characterization of aluminum loaded SBA-type materials as catalyst for polypropylene degradation reaction Obali, Zeynep; Sezgi, Naime Aslı; Doğu, Timur (2011-12-01) The performance of pure and aluminum containing SBA-type catalysts prepared using different aluminum sources and different Al/Si ratios were investigated in the polypropylene degradation reaction using a thermogravimetric analyzer. For the synthesis of catalysts, aluminum isopropoxide and aluminum sulphate were used as the aluminum sources. Synthesized materials had high surface areas and exhibited nitrogen adsorption isotherms of type IV. EDS results showed that the aluminum incorporation into the structur...
Characterization of lignocellulose biomass and model compounds by thermogravimetry Kök, Mustafa Verşan (Informa UK Limited, 2017-01-01) In this research, combustion characteristics of lignocellulose biomass (hazelnut shell) and three main components (cellulose, hemicellulose, and lignin) were investigated using thermogravimetry (TGA-DTG) technique at different heating rates. The ignition, peak, burn-out temperatures, and the heat liberation of lignocellulose biomass and three main components were also measured. Two different model-free kinetic methods, known as Ozawa-Flynn-Wall (OFW) and Kissinger-Akahira-Sunose (KAS), were used in order to...
A MODEL FOR PASTEURIZATION WITH MICROWAVES IN A TUBULAR FLOW REACTOR OZILGEN, S; OZILGEN, M (Elsevier BV, 1991-05-01) Thermal death kinetics of Escherichia coli with microwaves were studied by using a tubular flow reactor with different diameters, lengths, and flow rates. Mathematical models were presented for temperature profile development and death of the microorganisms along the reactor. A first-order kinetic expression in biomass concentration simulated the death phenomena. Temperature effects on the death rate constant were expressed with an Arrhenius expression. Numerical values of the constants of this expressi...
