This study comprises of the computation of instantaneous fuel consumptions as a straight means for the interpretation of combustion-related characteristics of coal. The model relies on the determination of the extent of combustion by the calculated fuel combustion amounts at specific instants in order to examine the oxidation behavior and possible influences governed by any variable of interest. In this context, coal briquettes prepared by varying dimensions with and without a volume constraint were evaluated and instantaneous fuel consumptions corresponding to the determined instants were computed for comparison rather than introducing the model with a single experiment. Thus, the influences imposed by the enlargement of the briquette volume as well as by the variations in the compactness of briquettes on the effectiveness and efficiency of combustion reactions were dealt. The applicability of the model was checked by the trends revealed from the view of reaction kinetics in terms of activation energies. At the end of the study, the results deduced on the grounds of instantaneous fuel consumption values were seen to have been in full confirmation by those related to reaction kinetics, showing the applicability of the model in reflecting the particular cases during a combustion reaction.

Modeling of CO2 storage in an oil reservoir Gumrah, F.; Dulger, M.; Gunaydin, D.; Senel, O. (Informa UK Limited, 2008-01-01) This study provides an overview for the carbon dioxide sequestration process in an oil reservoir by using the software CMG's GEM. Different scenarios are applied for the oil reservoir description. Firstly, a single layered reservoir is considered and simulation studies are performed, as this reservoir is homogeneous, heterogeneous and fractured. Secondly, a multi-layered reservoir is examined. In the second case, a heterogeneous system and a heterogeneous system composed of homogenous layers are selected. F...
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...
Enhancement of hydrogen storage properties of Ca3CH antiperovskite compound with hydrogen doping Gencer, Ayşenur; Surucu, Gokhan (Wiley, 2020-01-01) The doping effect of hydrogen on the Ca3CHx (x = 1, 4, 7, 9, and 10) antiperovskite compounds has been examined using density functional theory (DFT). The results of the structural optimizations show that all these compounds have negative formation energy implying the energetic stability and synthesizability. The band structures that are essential for the electronic properties have been determined along with the partial density of states (DOS) showing the metallic behavior of these compounds. In addition, t...
Economical Evaluation of an Oil Field Reservoir Kök, Mustafa Verşan (Informa UK Limited, 2011-01-01) In this study, economical evaluation of an oil field reservoir was performed using software. The software used in this study consists of different sub-programs to determine recoverable oil, recovery factor, initial and final productions, production rates, and original oil and gas in place for different types of reservoirs. Recovery efficiency was found to be 29% for water drive and 4.78% for solution gas drive reservoirs. In decline curve analysis, initial and final production rates were obtained as 40 and ...
Influence of coal briquette size on the combustion kinetics Altun, Naci Emre; Bagci, AS (Elsevier BV, 2004-08-15) In this study, the effects of one of the most important parameters in coal briquetting process, the briquette size, on the combustion behaviour of coal briquettes were determined from the view of combustion kinetics, i.e. their liability to ignite and combust. Effect of size on the combustion kinetics was treated by two different approaches. The first one consists of combustion kinetics experiments with briquettes of increasing sizes, thus of expanding volumes. In the second phase, briquette dimensions were...
