Thermal analysis and kinetics of biomass samples
Kök, Mustafa Verşan (2013-02-01)
In this research, combustion behavior of agricultural residues known as miscanthus, poplar wood, and rice husk was investigated using thermal analysis techniques. Differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG) techniques were used. Combustion experiments were performed at five different heating rates (5, 10, 15, 25, and 50 degrees C/min). The reaction regions, ignition and burnout temperatures, heat flow rate values of biomass samples are determined. Activation energy of the biomass s...
Thermal analysis of eutectic modified and grain refined aluminum-silicon alloys
İslamoğlu, H. Erol; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2005)
A series of AlSi9Mg alloys were prepared and tested to reveal the effect of addition sequence and timing of grain refiner and eutectic modifier. AlSr10 master alloy was used as an modification reagent, and also for grain refiner AlTi5B master alloy was used. The depression at the eutectic temperature due to the addition of modifier and decrease in the amount of undercooling at the liquidus due to the presence of grain refiner were examined by the cooling curves which were obtained by the Alu-Therm instrumen...
Thermal characterization, combustion and kinetics of different origin crude oils
Gundogar, Asli S.; Kök, Mustafa Verşan (2014-05-01)
In this research, the combustion behavior of six Turkish crude oils (light and medium type) was investigated by thermogravimetry/derivative thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC) methods under atmospheric air in the absence of rock matrix. Two main reaction intervals were observed on all thermograms known as low temperature oxidation (LTO) and high temperature oxidation (HTO) regions. The resulting curves showed that the mass loss under combustion is accompanied by exothermic ...

The effect of co-firing of biomass fuels with oil shale on combustion was investigated Thermogravimetric analysis and differential scanning calorimetry were the tools used to perform the investigation. Since the combustion of biomass is highly exothermic, biomass fuels can serve as an appropriate fuel feedstock. Biomass fuels producing much volatile matter and containing less cellulose are good candidates for co-firing with oil shale. The biomass samples used in the study were hazelnut shell, wheat bran, po...
Thermal Analysis of Crude oil lignite mixtures by Differential Scanning Calorimetry
Kök, Mustafa Verşan (Elsevier BV, 1994-04-01)
Thermal characterization of lignite, crude oils and their 10 and 20% mixtures were investigated by differential scanning calorimetry (d.s.c.). The calorific value of the lignite increased in mixtures depending on the crude oil type. In pyrolysis runs, temperature ranges where distillation and visbreaking occur were identified for the crude oils studied. The effect of heating rate was also studied, and higher reaction temperatures and higher heat flow rates were observed at d.s.c. peak thermograms with incre...
