In this study, an asphaltic Turkish crude oil was treated with alkali solution (NaOH) at different concentrations to simulate an alkali EOR technique. IFT (interfacial tension) measurements were carried out by ring method and the yields of asphaltene is precipitated after the process. Thermal properties of these asphaltenes were investigated by thermal analysis methods (thermogravimetry, TG/DTG and differential scanning calorimeter, DSC) to infer the possible changes in the asphaltene molecules and their behavior during refinery or fuel purposes.

Optimising clarification of carrot juice by bacterial crude pectinase
Uzuner, Sibel; Çekmecelioğlu, Deniz (2015-12-01)
This study was undertaken to search for potential use of crude bacterial pectinase enzyme produced from Bacillus subtilis grown on hazelnut shell hydrolysate in clarification of carrot juice and to optimize the enzyme load, pH and time using the Box-Behnken response surface methodology (RSM). The carrot juice was treated with the crude pectinase enzyme (5.60 U mL(-1)) at different concentrations (0.1-0.5%), pH (4-7), and time (2-6 h). The obtained enzyme was also compared with commercial fungal pectinase at...
Cadmium removal using clinoptilolite : influence of conditioning and regeneration
Gedik, Kadir; İmamoğlu, İpek; Department of Environmental Engineering (2006)
Clinoptilolite samples obtained from two deposits in Turkey were tested for their potential in removing cadmium from aqueous solutions. Preliminary experiments in batch mode revealed inferior cadmium uptake at low pH. Particle size was found to have no effect on cadmium removal efficiency suggesting the use of exchangeable cations found in the internal/available sites. Increasing temperature yielded positive, whereas prewashing had no effect on cadmium removal using both clinoptilolite samples. The Langmuir...
3-d model studies of alkaline flooding using horizontal wells
Bağcı, Ali Suat (Informa UK Limited, 2004-07-02)
In this study, the effect of sodium hydroxide (NaOH) solution for the improved oil recovery of Garzan (26degreesAP1) crude oil was investigated using two different laboratory models. The effect of injection rate on oil recovery was investigated using a one-dimensional unconsolidated limestone reservoir model. The effect of horizontal and vertical well configurations on oil recovery was also studied using a 3-D physical model and various well configurations. As previously studied, the interfacial tension mea...
Improvement in magnetic properties of La substituted BaFe12O19 particles prepared with an unusually low Fe/Ba molar ratio
Sozeri, H.; KÜÇÜK, İLKER; Ozkan, H. (2011-07-01)
In this study, effect of lanthanum substitution on the phase composition, lattice parameters and magnetic properties of barium hexaferrite has been studied in samples synthesized in ammonium nitrate melt. Samples, prepared with different lanthanum amount and having various initial Fe/(Ba + La) ratios in between 12 and 2 {(Ba1-xLax).n Fe2O3, where 0 <= x <= 1 and 1 <= n <= 6)}, are sintered at temperatures from 800 to 1200 degrees C. The lattice parameters, both a and c, decreases with increasing La amount w...
Investigation of single-walled carbon nanotube growth parameters using alcohol catalytic chemical vapour deposition
Ünalan, Hüsnü Emrah (2005-10-01)
A detailed parametric study of single-walled carbon nanotubes (SWNTs) synthesized in powder form and on substrates using the alcohol catalytic chemical vapour deposition (ACCVD) method is reported. As-grown SWNTs were analysed using transmission electron microscopy (TEM), field-emission scanning electron microscopy (FE-SEM), Raman spectroscopy and UV-vis-NIR spectroscopy to obtain structural and electronic information. We found that nucleation and growth of SWNTs occurs within seconds after introduction of ...
