Dark fermentative bio-hydrogen production from sugar-beet processing wastes Özkan, Leyla; Demirer, Göksel Niyazi; Department of Environmental Engineering (2009) In this study, bio-hydrogen generation potential of sugar-beet processing wastes (sugar-beet processing wastewater and beet-pulp) through dark fermentation was investigated. For this purpose, four different experimental set-ups were used. In the first set-up, sugar-beet processing wastewater was used along with four different cultures to investigate the effect of culture type on bio-hydrogen production. In addition, unseeded reactor was prepared to investigate bio-hydrogen production potential of indigenous...
Dark fermentative hydrogen production from sucrose and molasses TUNÇAY, EKİN GÜNEŞ; Bayramoğlu, Tuba Hande; EROĞLU, İNCİ; Gündüz, Ufuk (2017-10-25) There are many factors affecting the dark fermentative hydrogen production. The interaction of these factors, that is, their combined effects, should be investigated for better design of the systems with stable and higher hydrogen yields. This study aimed to investigate the combined effects of initial substrate, pH, and biomass (or initial substrate to biomass) values on hydrogen production from sucrose and sugar-beet molasses. Therefore, optimum initial chemical oxygen demand (COD), pH, and volatile suspen...
Light crude oil combustion in the presence of limestone matrix Kök, Mustafa Verşan; Keskin, C; Madarasz, J; Bagci, S (Springer Science and Business Media LLC, 2004-01-01) In this study the combustion characteristics of crude oils (Karakus and Beykan) in the presence of a limestone matrix were determined using the thermogravimetry (TG/DTG). Experiments were performed at a heating rate of 10degreesC min(-1), whereas the air flow rate was kept constant at 10 L h(-1) in the temperature range of 20-900degreesC. In combustion with air, three distinct reaction regions were identified in all crude oil/limestone mixtures studied known as low temperature oxidation (LTO), fuel depositi...
Dark conduction mechanisms of PTQBDT based heterojunction diode Gullu, H. H.; Yildiz, D. E.; Hacioglu, S. O.; Çırpan, Ali; Toppare, Levent Kamil (2023-01-01) Al:LiF/PTQBT:PCBM/PEDOT:PSS/ITO/glass organic-based diode is fabricated with different weight ratios in PTQBT:PCBM active layer. The diodes D1, D2 and D3 are prepared using the precursor solution for spin coating process as 1:2, 1:3 and 1:4, respectively. Under dark, main diode parameters are extracted by conventional thermionic emission theory using the results of measurements. Parasitic resistance contribution, non-ideal barrier height formation and high values of ideality factor indicate possible effects...
Dark electrical conductivity and photoconductivity of Ga(4)Se(3)S layered single crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (2008-11-01) Ga(4)Se(3)S layered crystals were studied through the dark electrical conductivity, and illumination- and temperature-dependent photoconductivity in the temperature region of 100-350 K. The dark electrical conductivity reflected the existence of two energy states located at 3 10 and 60 meV being dominant above and below 170 K, respectively. The photoconductivity measurements revealed the existence of another two energy levels located at 209 and 91 meV above and below 230 K. The photoconductivity was observe...
