Methane to Methanol Conversion on Copper- Containing Small-Pore Zeolites

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...
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...

Hydrogen and poly-beta-hydroxybutyric acid production at various acetate concentrations using Rhodobacter capsulatus DSM 1710 Demiriz, Burcu Ozsoy; Kars, Gokhan; Yucel, Meral; EROĞLU, İNCİ; Gündüz, Ufuk (2019-06-28) In the present study, Rhodobacter capsulatus DSM 1710 was cultured in media having various concentrations of acetate (10-65 mM) to investigate simultaneous production of hydrogen and PHB. The highest cumulative hydrogen productions were observed using 50 mM (11.7 mmol H-2) and 65 mM (11.4 mmol H-2) acetate. However, molar productivity values were higher at 25 mM (0.50 mmol/Lc.h) and 50 mM (0.44 mmol/Lc.h) compared to 65 mM (0.35 mmol/Lc.h). Furthermore, the highest PHB production (234.7 mg/L) was attained u...
