Bi-functional nanostructured novel catalysts for dimethyl ether synthesis
Çelik, Gökhan; Doğu, Timur; Özbelge, H. Önder; Department of Chemical Engineering (2012)
Excessive use of fossil fuels shall result in the significant energy problems in the coming century and causes global warming by CO2 emission. Use of petroleum in transportation constitutes the dominant part of total petroleum use. Researches on non-petroleum based, environmentally friendly alternative fuels have been ascended in last decades. Among the alternative fuels, DME has been considered as an attractive fuel alternate due to high cetane number, low PM (particulate matter) and low NOx emission. Synt...
Production and performance evaluation of ZIF-8 based binary and ternary mixed matrix gas separation membranes
Keser, Nilay; Yılmaz, Levent; Kalıpçılar, Halil; Department of Chemical Engineering (2012)
Mixed matrix membranes (MMMs) have gained importance because they combine the desirable properties of the polymers and the organic/inorganic filler materials and they may have a very big potential. In this study polyethersulfone (PES) was used as polymeric material, and Zeolitic Imidazolate Framework-8 (ZIF-8) was used as porous filler material, and 2-hydroxy 5-methyl aniline(HMA), was used as a third component in membrane formulation. In this study, ZIF-8 crystals were synthesized with varying particle siz...
Zr and silicotungstic acid incorporated silicate structured mesoporous catalysts for dimethyl ether synthesis
Orman, Sultan; Doğu, Timur; Department of Chemical Engineering (2011)
Due to high consumption rates of petroleum derived fuels and environmental regulations, significant search has been initiated for the development of environmental friendly and efficient fuels, which were derived from more abundant feedstocks. Dimethyl ether (DME), as having a good combustion quality and high cetane number, is an efficient alternative for diesel fuel. With improved combustion quality, the emissions from DME used engines are greatly decreased. DME synthesis can be carried out via two differen...
First principles investigation of hydrogen storage in intermetallic systems
Kınacı, Alper; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2007)
The design and production of efficient metal-hydrides for hydrogen storage is a long standing subject. Over the years, many different types of intermetallic hydride systems were studied and some of them came out to be operable. However, none of them meet all the storage criteria perfectly. In this study, total energies, hydrogen storage capacity and stability of AB (A = Al, Be, Cu, Fe, Ni, Sb, V and B = Ti) type intermetallics were investigated with the goal of spotting a potential hydrogen storage material...
Ruthenium(III) acetylacetonate as catalyst precursor in the dehydrogenation of dimethylamine-borane
Ünel, Ebru; Özkar, Saim; Department of Chemistry (2011)
Amine boranes have recently been considered as solid hydrogen storage materials with high capability of hydrogen storage. Dimethylamine borane is one of the promising amine boranes with high theoretical gravimetric capacity of 16.9 wt%. Dimethylamine borane can undergo dehydrogenation only in the presence of a suitable catalyst at moderate temperature. In this project, throughout the dehydrogenation of dimethylamine borane (DMAB), the catalytic activity of ruthenium(III) acetylacetonate was examined for the...
