Direct and selective conversion of methane to methanol is a challenging reaction due to the inherent stability of methane [1]. It is known that methane can be converted to methanol on Cu-ZSM-5 and Cu- mordenite zeolites in a batch process [2-4], but the highest reported yield is only 13µmol methanol/gzeolite [5]. The reactive copper species on Cu-ZSM-5 was found to be a mono-μ-oxo-dicopper complex ([Cu–O–Cu]2+) based on an absorption feature at 22,700 cm-1 in UV–vis spectra [3,5] and several unique features in resonanceenhanced Raman spectra [6]. This species is reported to form in O2 at high temperatures (380- 450°C) [3]. We investigated conversion of methane to methanol on copper (II)-exchanged small-pore (8- membered ring) zeolites; Cu-SSZ-13 (CHA), Cu-SSZ-16 (AFX) and Cu-SSZ-39 (AEI). All the samples were active for the formation of methanol. The materials were characterized with UV– vis and Raman spectroscopy after O2 treatment to understand the structure of the reactive copper species.

Carbon dioxide reforming of methane on Ni-based bimetallic catalyts Ay, Hale; Üner, Deniz; Department of Chemical Engineering (2014) Carbon dioxide reforming of methane is a promising process for the utilization of two important greenhouse gases and the production of synthesis gas with a lower H2/CO ratio which is preferred in Fischer–Tropsch synthesis. Ni catalysts have taken great interest in dry reforming of methane due to their high catalytic activity, easy availability and low cost. However, the main restriction of Ni-based catalysts is the formation of carbon which causes catalyst deactivation. The objective of this thesis was to r...
Catalytic conversion of methane to methanol on Cu-SSZ-13 using N2O as oxidant İpek Torun, Bahar (2016-01-01) Direct catalytic methanol production from methane is achieved on Cu-SSZ-13 zeolite catalysts using N2O as the oxidant. The methanol production rate on Cu-SSZ-13 (on a per gram basis) was more than twice the rate on Cu-mordenite and more than four times the rate on Cu-ZSM-5.
Methane to higher hydrocarbons via halogenation Degirmenci, V; Üner, Deniz; Yılmaz, Ayşen (Elsevier BV, 2005-10-15) Activation of methane with a halogen followed by the metathesis of methyl halide is a novel route from methane to higher hydrocarbons or oxygenates. Thermodynamic analysis revealed that bromine is the most suitable halogen for this goal. Analysis of the published data on the reaction kinetics in a CSTR enabled us to judge on the effects of temperature, reactor residence time and the feed concentrations of bromine and methane to the conversion of methane and the selectivity towards mono or dibromomethane. Th...
Investigation of the interaction of CO₂ and CH₄ hydrate for the determination of feasibility of CO₂ storage in the Black Sea sediments Örs, Oytun; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2012) Recently, carbon dioxide injection into deep sea sediments has become one of the carbon dioxide mitigation methods since carbon dioxide hydrates are stable at the prevailing pressure and temperature conditions. The Black Sea, which is one of the major identified natural methane hydrate regions of the world, can be a good candidate for carbon dioxide storage in hydrate form. Injected carbon dioxide under the methane hydrate stability region will be in contact with methane hydrate which should be analyzed tho...
Methane activation via bromination over sulfated Zirconia/SBA-15 catalysts Değirmenci, Volkan; Üner, Deniz; Department of Chemical Engineering (2007) Methane activation with bromine followed by the condensation of the methyl bromide into higher hydrocarbons or oxygenates is a novel route. However, the selective production of monobrominated methane (CH3Br) at high conversions is a crucial prerequisite. A reaction model was developed according to the kinetic data available in the literature and thoroughly studied to investigate the optimum reactor conditions for selective methane bromination in gas phase. It was concluded that at high methane (>90%) conver...
