In this thesis work, it was aimed to optimize the conditions to produce silicon carbide (SiC), from rice husks from Turkish Thrace Region, via pyrolysis. Rice husks, coked at 500oC, were high energy ball-milled prior to pyrolysis, in order to investigate the effects of ball-milling on pyrolysis temperature, pyrolysis time and morphology of the SiC produced. Samples of rice husks subjected to different ball milling conditions, were pyrolyzed at temperatures varying from 1500oC to 1600oC and for times varying from ½ hour to 2 hours. Results of experiments showed that, ball-milling reduced the pyrolysis temperature and pyrolysis time to some extent. It was also experimentally shown that ball-milling favored the formation of SiC particles rather than formation of SiC whisker.

Experimental research on in-tube condensation under steady-state and transient conditions Tanrikut, A; Yesin, O (2005-01-01) In this research study, in-tube condensation in the presence of air was investigated experimentally at a heat exchanger of countercurrent type for different operating conditions. The test matrix for the steady-state condition covers the range of pressures P = 1.8 to 5.5 bars, vapor Reynolds numbers Re, = 45 000 to 94 000, and inlet air mass fraction values Xi = 0 to 52%. The effect of air manifests itself by a reduction in the local heat flux and the local heat transfer coefficient. The local heat transfer ...
STEAM-CO-2 FLOODING - AN EXPERIMENTAL-STUDY GUMRAH, F; OKANDAN, E (1992-01-01) Research on the use of the combined steam-CO2 injection process was conducted in linear and three-dimensional unscaled laboratory models to determine the performance of limestone reservoirs of the Turkish oil fields, Garzan, Bati Raman and Camurlu. This study was carried out to evaluate the benefits Of CO2 addition to steam on the recovery of 24-degrees-API, 12-degrees-API and 10.6-degrees-API gravity oils.
Thermal Degradation of Polylactide and Its Electrospun Fiber Ozdemir, Esra; Hacaloğlu, Jale (2016-01-01) Thermal degradations of poly(lactic acid), (PLA) and its fiber were studied via direct pyrolysis mass spectrometry. As the amount of PLA pyrolyzed was increased the relative yields of protonated and cyclic oligomers were increased indicating that inter-molecular interactions were promoted. Hydrolysis reactions caused significant decrease in the relative yields of high mass products. Intermolecular trans-esterifications were more effective during the pyrolysis of PLA fiber. On the other hand, PLA fiber showe...
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.
Investigation of the production of silicon nitride from Turkish rice husks Alpay, Barış Yiğit; Topkaya, Yavuz Ali; Geveci, Ahmet; Department of Metallurgical and Materials Engineering (2014) Production of silicon nitride by the carbothermal reduction and nitridation of silicon dioxide in rice husk was investigated. For this purpose, rice husks from the Black Sea region (Bafra) of Turkey was obtained. The husks were subjected to a pretreatment step involving water washing, acid leaching and pyrolysis at 600C. Pyrolyzed rice husks were found to have a Carbon:Silicon Dioxide molar ratio of about 5.2. Pyrolyzed rice husks were used as the starting material for the carbothermal reduction and nitrida...
