In this study, thermal features and reaction kinetics of the raw Çorum-Alpagut Lignite, Zoııguldak-Üzülmez Bituminous Coal and Şırnak-Avgamasya Asphaltite were investigated through a qualitative and quantitative comparison via Thermogravimetric Analysis (TG/DTG) and an Arrhenius Type Kinetic Model, in order to determine the liability to ignite and effectiveness of the combustion of the concerned fuels as well as the critical points during their reaction periods. At the end of experiments, Alpagut Lignite, Üzülmez Bituminous Coal and Avgamasya Asphaltite resulted in different combustion features in terms of residue left, peak temperatures and activation energies from which the combustion behaviour of these fuels can be interpreted in details.

Determination of kinetic parameters and hydrogen desorption characteristics of MgH2-10 wt% (9Ni-2Mg-Y) nano-composite Pourabdoli, Mehdi; Raygan, Shahram; Abdizadeh, Hossein; Üner, Deniz (2013-09-10) Hydrogen desorption kinetic parameters of MgH2 compounds were measured and compared with published gas solid reaction models. The compounds investigated in this study were as-received MgH2, ball milled MgH2, and MgH2 ball milled with 9Ni-2Mg-Y catalyst compound. It was determined that different models were necessary to fit the hydrogen desorption data collected at different temperatures on the same sample, indicating that desorption mechanisms changed with respect to temperature. Addition of (9Ni-2Mg-Y) all...
Prediction of Non-Darcy flow effects on fluid flow through porous media based on field data Alp, Ersen; Akın, Serhat; Department of Chemical Engineering (2012) The objective of this dissertation is to investigate the non-Darcy flow effects on field base data by considering gas viscosity, gas deviation factor and gas density as variables. To achieve it, different correlations from the literature and field data have been combined to Sawyer-Brown Method, thus a contribution has been achieved. Production history of selected gas field has been implemented to a numerical simulator. To find out non-Darcy effects quantitatively, Darcy flow conditions have also been run in...
Comparison of Fenitrothion and Trifluralin Adsorption on Organo-Zeolites and Activated Carbon. Part II: Thermodynamic Parameters and the Suitability of the Kinetic Models of Pesticide Adsorption LÜLE ŞENÖZ, Güzide Meltem; Atalay, Mustafa Ümit (Informa UK Limited, 2014-07-04) The suitability of two kinetic models and the thermodynamic parameters of pesticide adsorption were investigated based on obtained data of previous studies. Kinetic evaluation indicated that the pesticides adsorption on adsorbents followed the pseudo-second-order model. Gibbs free energy (Delta G degrees), enthalpy (Delta H degrees), and entropy (Delta S degrees) were calculated for thermodynamic parameters by using linearized Arrhenius equation. The results indicated that the sorption process of fenitrothi...
Comparison of single particle combustion behaviours of raw and torrefied biomass with Turkish lignites Magalhaes, Duarte; Panahi, Aidin; Kazanç Özerinç, Feyza; Levendis, Yiannis A. (Elsevier BV, 2019-04-01) This study investigated the combustion behaviour of single pulverized biomass and lignite coal particles under high temperature-high heating rate conditions. Selected fuels included three important agricultural residues in Turkey (olive residue, almond shell, and hazelnut shell), and two lignite coals from the regions of Tuncbilek and Soma in Turkey. Biomass fuels were either raw or torrefied at 275 degrees C for 30 min in nitrogen. The biomass fuels were sieved to a size cut of 212-300 mu m, and the coals ...
Comparative Pyrolysis and Combustion Kinetics of Oil Shales Kök, Mustafa Verşan (2000-02-01) In this research, thermal characteristics and kinetic parameters of eight Turkish oil shale samples were determined by thermogravimetry (TG/DTG) at non-isothermal heating conditions both for pyrolysis and combustion processes. A general computer program was developed and the methods are compared with regard to their accuracy and the ease of interpretation of the kinetics of thermal decomposition. Activation energies of the samples were determined by five different methods and the results are discussed.
