CO hydrogenation over a catalyst with the nominal composition of 6.3% Mn-2.5% Ru/Al2O3 was studied in a now system with a differential fixed-bed reactor operating under atmospheric pressure. The temperature was varied between 553-613 K, H-2/CO ratio 1-3 and space velocity 5100-27600 cm(3)/(g h). The presence of manganese caused the product distribution to shift to lower olefins. For this catalyst system, secondary alkene hydrogenation was found to be significant. The activity and selectivity pattern of the catalyst altered appreciably at/below and above 573 K. It is hypothesized that at/below 573 K, monolayer carbon deposits and above 573 K multilayer carbon deposits affect the performance of the catalyst.

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...
Hydrogen production over molybdenum loaded mesoporous carbon catalysts in microwave heated reactor system Guler, Melih; Doğu, Timur; VARIŞLI, DİLEK (2017-12-15) Ammonia decomposition reaction to produce COx free hydrogen over molybdenum incorporated mesoporous carbon based catalysts was studied in a microwave heated reactor system. Mesoporous carbon is acting as the catalyst support as well as the microwave receptor in the reaction medium. While the highest conversion value was 49% in conventionally heated reaction system at 600 degrees C, total conversion value was achieved over the same catalyst at 400 degrees C in microwave heated system with a GHSV of 36,000 ml...
Activity-corn position relations in MuCr(2)O(4)-CoCr2O4 solid solutions and stabilities of MnCr2O4 and CoCr2O4 at 1300 degrees C Koc, N; Timucin, M (Wiley, 2005-09-01) Phase equilibria in the system MnO-CoO-Cr2O3 were investigated at 1300 degrees C under controlled oxygen partial pressures by using the gas equilibration technique. The CoO activities in various phase assemblages of the system were measured by determining the partial pressures of oxygen in the gas phase for coexistence with metallic cobalt. The activity data revealed that at 1300 degrees C, MnO-CoO and MnCr2O4-CoCr2O4 solid solutions exhibit mild positive departures from ideal behavior. The activities in th...
Direct Methane Oxidation to Methanol by N2O on Fe- and Co-ZSM-5 Clusters with and without Water: A Density Functional Theory Study Fellah, Mehmet Ferdi; Önal, Işık (2010-02-25) Density functional theory (DFT) calculations were carried Out ill a Study of oxidation of methane to methanol by N2O on the Fe- and Co-ZSM-5 clusters. The catalytic cycle steps have been Studied oil model Clusters ((SiH3)(4)AlO4M) (where M = Fe, Co). Calculations indicate very low methanol selectivity Without water and increasing rate of methanol formation with water. These results are in qualitative agreement with the experimental literature. The methanol formation step is also found to be the rate-limitin...
The effects of alkali promoters on the dynamics of hydrogen chemisorption and syngas reaction kinetics on Ru/SiO2 surfaces Üner, Deniz; Pruski, M; King, TS (1997-01-01) The dynamics of chemisorbed hydrogen on unpromoted and promoted Ru/SiO2 catalysts was studied by means of single pulse and selective excitation H-1 NMR spectroscopy. Dynamic NMR studies indicated a reduced mobility of hydrogen in the presence of alkali promoters (Na and K) at high loadings (65 atomic %). On unpromoted Ru/SiO2 catalysts, the line due to hydrogen-on-metal was homogeneously broadened at pressures above 0.5 Torr H-2. Similar behavior was observed on promoted Ru/SiO2 catalyst with 66 atomic % K....
