In this research, thermogravimetric and mass-spectrometric (TG-MS) analysis and kinetics of coal biomass blends (25, 50 and 75 wt%) was studied. All the experiments were performed at 20 degrees C/min. heating rate and under air atmosphere. The reaction regions, peak and burn-out temperatures, mass loss, maximum mass loss rate, combustion index and residue of the samples was determined. This research also focused on the main volatile products release, such as H-2, O-2, CO, CO2 and hydrocarbons from coal biomass blends combustion on the basis of both their relative intensities across the temperature range 150-750 degrees C and on their relevancy. The major release of COS is observed in decomposition stage, whereas significant SO2 release is noticed from combustion. When the percentage of biomass is increases in the coal-biomass blends, maximum rate of mass loss increases indicating the higher reactivity of the samples. The kinetic parameters of the coal-biomass blends were calculated using two different methods (Arrhenius and Coats & Redfern). The activation energy and Arrhenius constant values were increased with the increasing biomass ratio in the blends.

Non-isothermal DSC and TG/DTG analysis of the combustion of silopi asphaltites
Kök, Mustafa Verşan (2007-06-01)
In this research, non-isothermal combustion and kinetics of Silopi (Turkey) asphaltite samples were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). A sample size of 10 mg, heating rates of 5, 10, 15 and 200C min(-1) were used in the temperature range of 20-600 degrees C, under air atmosphere. Two reaction regions were observed in DSC curves. The first region is due to the evaporation of moisture in asphaltite sample whereas, release of volatile matter and burning of ca...
Pyrolysis, combustion and gasification studies of different sized coal particles using TGA-MS
Jayaraman, Kandasamy; Kök, Mustafa Verşan; Gokalp, Iskender (2017-10-01)
In this research, thermogravimetric and mass-spectrometric (TG-MS) analysis and kinetics of different sized (60 mu m,800 mu m, and 3 mm) Saray (Turkish origin) coal is examined at various combustion temperature ranges. Experiments are performed at the heating rate of 40 degrees C/min in an argon atmosphere up to combustion/gasification temperatures (850-1150 degrees C), which, is close to the conditions of fluidized bed systems for high ash coal applications. The combustion tests are performed at isothermal...
An investigation into the thermal behavior of coals
Kök, Mustafa Verşan (2002-10-01)
The thermal behavior of 4 coal samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) methods. Upon heating the coals in an inert atmosphere up to 800degreesC, 31.44-43.82% weight loss occurs. The 2 temperature regions of increased chemical reactivity are evident in the coal samples studied Two different models determined kinetic analysis of the samples, and the results are discussed.
Thermal characterization and gasification kinetics of thrace-saray region coal
Yıldırım, Betül; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2015)
In this thesis being up as-received and washed and dried, two different coal samples from Saray-Edirkoy field were experimented in order to determine effects of different variables as coal type, heating rate, gas flow rate, isothermal duration, gasifying medium, and final gasification temperature, on isothermal gasification profiles of the coal samples. In the scope of this study, heating rate was changed in the range of 20-50oC/min as 20, 30, 40 and 50oC/min whereas two different gas flow rate values as 60...
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...
