Investigation of Combustion Kinetics of Five Waste Wood Samples with Thermogravimetric Analysis Yorulmaz, Sema Yurdakul; Atımtay, Aysel (2007-02-24) In the present study, combustion mechanisms, thermal kinetics, and phases of combustion were investigated for untreated pine and treated MDF, plywood and particleboard samples. Waste wood samples were combusted in air at 10, 20 and 30 degrees C/min heating rates in TGA. As a result of TG analysis, thermal decomposition of treated samples was observed at lower temperatures as compared to the untreated pine sample because of the catalyzing effects of the chemicals in the samples. Therefore, there were less fl...
Investigation of combustion kinetics of treated and untreated waste wood samples with thermogravimetric analysis Yorulmaz, Sema Yurdakul; Atımtay, Aysel (2009-07-01) In the present study, combustion mechanisms, thermal kinetics, and phases of combustion were investigated for waste wood samples (untreated pine and treated MDF, plywood and particleboard). Waste wood samples were combusted in air at 10, 20 and 30 degrees C/min heating rates in TGA. The results of TG analysis have shown that thermal decomposition of treated samples takes place at lower temperatures as compared to the untreated pine sample because of the catalyzing effects of the chemicals in the samples. Th...
Investigation of properties of diesel water mixtures with and without emulsifier by terahertz spectroscopy Çınar, Zühra; Esentürk, Okan; Department of Chemistry (2017) Additives such as alcohol, water are used in petroleum products for different purposes. Aim of the thesis is to determine water content in diesel water mixtures in THz region. The samples with and without emulsifier were analyzed in THz region. Besides, different kinds of oils (olive oil, sunflower oil, frying oil and engine grease #10) were measured in THz region because mixed of oils can be used instead of regular diesel. For this reason, we aimed to show distinguishability of regular diesel and mixed fue...
Investigation of glucose electrooxidation mechanism over N-modified metal-doped graphene electrode by density functional theory approach Duzenli, Derya; Önal, Işık; Tezsevin, Ilker (2022-10-01) In this work, various precious and non-precious metals reported in the literature as the most effective catalysts for glucose electrooxidation reaction were investigated by the density functional theory (DFT) approach in order to reveal the mechanisms taking place over the catalysts in the fuel cell. The use of a single-atom catalyst model was adopted by insertion of one Au, Cu, Ni, Pd, Pt, and Zn metal atom on the pyridinic N atoms doped graphene surface (NG). beta form of d-glucose in alkaline solution wa...
Investigation of Turkish lignites and biomass at high heating rates by using wire mesh apparatus Baghirzade, Mammadbaghir; Kazanç Özerinç, Feyza; Department of Micro and Nanotechnology (2018) Coal continues to play a significant role in energy production over the world. However, its limited procurement and enormous side effects on global warming, make governments and organizations turn towards renewable energy resources like biomass which is CO2 neutral. Prior to utilization of fuels in power plants, it is important to investigate fuel behavior at high temperatures and high heating rates, i.e., close to heating rates in industrial applications. This understanding enables engineers to design appr...
