In this research, experimental adsorption measurements for a Dadas shale sample were conducted at various pressures (up to 13 790 kPa (2000 psia)) and temperatures (25, 50, and 75 degrees C) using pure methane (CH4). The effects of temperature and pressure on adsorption were observed. As pressure increases, CH4 adsorption increases. However, as temperature increases, CH4 adsorption decreases. Moreover, by using Langmuir isotherm and Ono-Kondo models, experimental adsorption results were evaluated and adsorption isotherms were constructed. Although Ono-Kondo and Langmuir isotherm models have similar fittings to the experimental adsorption data of Dadas shale, Ono-Kondo models have several advantages. Different from Langmuir isotherms, the volume of adsorbed fluid, absolute adsorption data, and surface area of Dadas shale sample were predicted by Ono-Kondo models. By comparing the results of the Ono-Kondo monolayer and three-layer models, the adsorption type of the Dadas shale sample was found as a monolayer (Type I). It was concluded that the Ono-Kondo monolayer model is capable of fitting adsorption isotherms, especially at high pressures for shale samples. For initial gas-in-place calculations, the equations derived using the Langmuir isotherm were modified by the Ono-Kondo monolayer model. For the first time, the Ono-Kondo monolayer model was used in the formula of initial gas-in-place calculation. This formula provides better adsorption data evaluation, initial gas-in-place amounts, and adsorbed gas ratios in shale gas reservoir conditions compared to the values obtained with the Langmuir isotherm. This method is suggested to be used in flow and gas production simulations of shale gas reservoirs.

Adsorption behaviour of shale gas reservoirs Merey, Sukru; Sınayuç, Çağlar (2018-01-01) Experimental adsorption measurements for one shale sample were conducted at 25 degrees C, 50 degrees C and 75 degrees C up to 2,000 psia by using pure methane (CH4) and pure carbon dioxide (CO2) to understand the behaviour of CH4 and CO2 adsorption on shales. The effects of temperature and pressure on CH4 and CO2 adsorption on the shale sample were observed. When temperature decreases from 75 degrees C to 25 degrees C, the adsorption capacity increases for both CH4 and CO2 adsorption. As pressure increases,...
Gasification kinetics of Thrace region coal by thermogravimetry analysis Kök, Mustafa Verşan (Elsevier BV, 2020-05-01) This study aimed at understanding the gasification kinetics of Thrace region coal samples performing isothermal carbon dioxide gasification experiments at five different temperatures (750, 825, 850, 900, 950 degrees C). Thermogravimetric analysis (TGA) experiments were carried out isothermally on as received, and washed and dried coal samples, proximate and ultimate analyses of which were conducted priority. Firstly, the activation energies (Ea) of both coal samples were calculated using first order kinetic...
Thermal characterization of crude oils by pressurized differential scanning calorimeter (PDSC) Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2019-06-01) In this research, pressurized differential scanning calorimeter (PDSC) were used to estimate the thermal and kinetic behaviour of two different crude oils from Tatarstan oil fields under three different pressures (100, 600, 2000 kPa) at a constant heating rate (10 degrees C/min). The heat flow curves of both crude oils indicated two reaction regions known as low temperature oxidation (LTO) and high temperature oxidation (HTO). The reaction intervals were shifted to lower temperature regions with the increas...
Trap distribution in TlInS2 layered crystals from thermally stimulated current measurements IŞIK, MEHMET; Goksen, K.; Hasanlı, Nızamı; Ozkan, H. (Korean Physical Society, 2008-02-01) We have carried out thermally stimulated current (TSC) measurements with the current flowing along the layer on as-grown TlInS2 layered single crystals in the low temperature range 10 - 110 K with different heating rates of 0.1 - 1.5 K/s. Experimental evidence was found for the presence of two shallow electron trapping centers with activation energies of 12 and 14 meV. Their capture cross sections have been determined as 2.2 x 10(-23) and 7.1 x 10(-25) cm(2), respectively. It was concluded that retrapping i...
Environmental isotopes and noble gases in the deep aquifer system of Kazan Trona Ore Field, Ankara, central Turkey and links to paleoclimate ARSLAN, Sebnem; Yazıcıgil, Hasan; Stute, Martin; Schlosser, Peter (2013-03-01) Environmental isotopes and noble gases in groundwater samples from the Kazan Trona Ore Field are studied to establish the temperature change between the Holocene and the late Pleistocene. Noble gas temperatures (NGTs) presented in this study add an important facet to the global paleotemperature map in the region between Europe and North Africa. The groundwater system under investigation consists of three different aquifers named shallow, middle and deep in which delta O-18 and delta H-2 vary from -8.10 part...
