Ten sapropels, deposited in three different basins of the eastern Mediterranean since the Miocene and selected from cores of the Deep Sea Drilling Programme have been characterised by elemental analysis; fluorescence, infra-red and NMR spectrometry, by pyrolysis-gas chromatography/mass spectrometry and by catalytic hydrogenation at moderately high pressure. The sapropels are Types I-II kerogens, which have been oxidised, probably by a front experienced, since their deposition. Only one, from the Cretan basin, contained structures from lignin. The others, typical of a marine deposition, possessed aromaticities of about 0.2. Their detailed organic structures are described.


Thermal Analysis of Crude oil lignite mixtures by Differential Scanning Calorimetry
Kök, Mustafa Verşan (Elsevier BV, 1994-04-01)
Thermal characterization of lignite, crude oils and their 10 and 20% mixtures were investigated by differential scanning calorimetry (d.s.c.). The calorific value of the lignite increased in mixtures depending on the crude oil type. In pyrolysis runs, temperature ranges where distillation and visbreaking occur were identified for the crude oils studied. The effect of heating rate was also studied, and higher reaction temperatures and higher heat flow rates were observed at d.s.c. peak thermograms with incre...

Twelve samples of coal from the three major depositional episodes which occurred on the North China Block during the Carboniferous, Permian and Jurassic Periods have been investigated. The samples varied in rank from high volatile bituminous coal to anthracite and, although the coals from the three sequences were formed from different plants under different climates, plots of random vitrinite reflectance against elemental H/C ratios were similar to those previously reported from coals deposited in Eurameric...
Performance Estimation of Water Flooding in Oil Recovery
Kök, Mustafa Verşan (Informa UK Limited, 2009-01-01)
In this research, a petroleum field (Field-A) having approximately 23.2 API gravity oil in a carbonate formation from southeast Turkey was studied. Field-A was put on production in 1989 and produced till now, which is very close to its economic lifetime. Thus, it was considered as a candidate for enhanced oil recovery and water injection. Reservoir rock and fluid data were first interpreted with available well logging, core, and drill stem test data. The data were then merged into CMG/STARS simulator. A his...
Beneficiation of Himmetoglu oil shale by flotation as a solid fuel substitute. Part 2. Process optimization by a statistical approach
Altun, Naci Emre; Hwang, HY; Bagci, AS (American Chemical Society (ACS), 2006-01-01)
The effects of the important flotation parameters on the cleaning process of the Himmetoglu oil shale from Turkey were investigated. The individual and multiple interaction effects of conditioning time, flotation time, pulp density, particle size, and frother dosage were determined using statistical analysis and factorial design of experiments. The influence of these parameters on the cleaning performance were evaluated in terms of ash yield, calorific value, and combustible recovery of the concentrates. XR...
A study on the effects of various combustion parameters on the mineral composition of Tuncbilek fly ash
Akin, Suleyman Sener; Magalhaes, Duarte; Kazanç Özerinç, Feyza (Elsevier BV, 2020-09-01)
This study investigated the mineral composition and morphology of ash obtained from laboratory equipment and power plant fly ash from a Turkish lignite. In accordance with this purpose, combustion experiments were conducted for different heating rates in a temperature range of 800-1000 degrees C using different laboratory scale equipment: drop tube furnace (DTF) (similar to 10(5) degrees C/s), wire mesh reactor (WMR) (similar to 10(3) degrees C/s) and muffle furnace (MF) (similar to 10 degrees C/min). The r...
