Combustion synthesis of calcium phosphate bioceramic powders
Tas, AC (Elsevier BV, 2000-12-01)
Calcium phosphate (hydroxyapatite and tri-calcium phosphate) bioceramics closely resembling, in chemical composition, those found in vivo in human bones have been synthesized by using novel synthetic body fluid solutions via the self-propagating combustion synthesis (SPCS) method. Powder characterization was performed by XRD: ICP-AES, FTIR and SEM.
Combustion performance of oil shale and biomass fuels and their blends
Özgür, Emre; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2014)
The aim of this thesis was to evaluate the co-combustion performance of different origins of oil shales (Ulukışla and Himmetoğlu regions of Turkey) and various biomass samples (hazelnut shell, wheat bran, poplar, and miscanthus) at different biomass proportions (10, 20, and 50% by weight) using thermogravimetric analyzer (TGA), differential scanning calorimeter (DSC), and thermogravimetric analyzer-mass spectrometer (TGA-MS) at different heating rates (10, 30, 50 oC/minute). The ignition temperatures of the...
Combustion kinetics of oil shales by reaction cell experiments
Kök, Mustafa Verşan; Bagci, S. (Estonian Academy Publishers, 2008-01-01)
In this study, kinetics parameters of combustion reaction of Seyitomer and Beypazari oil shales were determined using Weijdema's model of reaction kinetics. The analysis of reaction kinetics experiments showed two different reaction regions at combustion of Beypazari oil shale sample. Only one reaction region was observed at combustion of Seyitomer oil shale. CO2/CO ratios increased gradually at low and medium temperatures and stabilized at high temperatures, especially after complete combustion. A decrease...
Combustion kinetics of crude oils
Kök, Mustafa Verşan (Informa UK Limited, 2002-01-01)
In this research, the reaction rates related to an in-situ combustion process were investigated and the effect of heating rate and crude oil type on the reaction rates were investigated. A laboratory model was used to run reaction kinetic experiments in unconsolidated limestone packs using three different crude oils. Experiments were performed under the same pressure and airflow rate and at two different heating rates. It was observed that oxidation of crude oil porous media follows a series of reactions. T...
Combustion Models for Industrial Applications (COMBINA)
Uzol, Oğuz(2013-2-28)
Combustion processes are an essential component of energy conversion and their accurate modeling is required if the objectives of reduction of fuel consumption and emissions are to be realized. Meeting these requirements will involve a substantial effort, in particular towards the development and availability of accurate and reliable simulation tools for reactive flows and more experimental data. In the COMBINA project, collaboration between a CFD software developing SME, which is coordinating this project,...
