Hydrogen sulfide sorption activities of manganese oxide and Mn-Fe-Cu mixed oxide sorbents were examined in a fixed bed reactor. Sulfur retention capacity of Mn-O sorbent was found to be quite high at 600 degrees C both in the absence and presence of hydrogen gas (0.17 and 0.14 g S/g sorbent, respectively). This sorbent has a high porosity and a relatively high surface area. Best regeneration temperature of this sorbent was found as 700 degrees C, with a gas stream containing 6% oxygen in nitrogen. Mn-Fe-Cu mixed oxide sorbent had a lower sulfur retention capacity (0.07 g S/g sorbent). However, both of these sorbents gave quite high initial sorption rate constants, resulting very sharp breakthrough curves. Deactivation model was shown to give good agreement with the experimental H2S breakthrough curves.

Breakthrough analysis of H2S removal on Cu-V-Mo, Cu-V, and Cu-Mo mixed oxides Yasyerli, S; Dogu, G; Ar, I; Doğu, Timur (2003-05-01) Kinetic studies carried out for the sorption of H2S in the presence and absence of hydrogen on Cu-V-Mo, Cu-V, and Cu-Mo mixed oxides gave detailed information about the reaction sequences. Formation of SO2 even in the presence of hydrogen at the initial stages of the sorption process showed the partial reduction of the metal oxides prior to the sulfidation step. A sorption experiment carried out with Cu-Mo mixed oxide gave incomplete sulfidation of molybdenum, whereas with Cu-V mixed oxide complete sulfidat...
Selective oxidation of H2S to elemental sulfur over Ce-V mixed oxide and CeO2 catalysts prepared by the complexation technique Yasyerli, Sena; Dogu, Gulsen; Doğu, Timur (2006-09-30) Selective oxidation of H2S to elemental sulfur was investigated in a fixed bed reactor using Ce-V mixed oxides and cerium oxide (CeO2) catalytic materials prepared by the complexation technique. The Ce-V mixed oxide with a V/Ce atomic ratio of one and with the CeVO4 crystal structure gave very high sulfur selectivity values (close to one) at almost complete conversion of H2S, for O-2/H2S mote ratios close to 0.5. Best operation temperature was found as 250 degrees C with this catalyst. CeO2 gave lower selec...
Activities of copper oxide and Cu-V and Cu-Mo mixed oxides for H2S removal in the presence and absence of hydrogen and predictions of a deactivation model Yasyerli, S; Dogu, G; Ar, I; Doğu, Timur (2001-11-14) Considering the importance of high-temperature removal of H2S from industrial gases, sorption studies were carried out on copper oxide and Cu-V and Cu-Mo mixed oxides in the absence and presence of hydrogen in a fixed-bed reactor. Experiments were carried out in a wide temperature range between 300 and 700 degreesC. A significant amount of SO2 was produced with CuO sorbent in the absence of hydrogen. In the case of mixed oxide sorbents, SO2 formation was detected even in the presence of hydrogen. On the bas...
Kinetics of hydrogen adsorption and Desorption on silica-supported Pt, Rh, and Ru catalysts studied by solid state H-1 NMR Savargaonkar, N; Üner, Deniz; Pruski, M; King, TS (2002-05-14) The kinetics of adsorption and desorption of hydrogen on the multifaceted surfaces of silica-supported Pt, Rh, and Ru catalysts were studied by means of solid state H-1 NMR. Experiments with selective inversion of 1H magnetization and the formalism developed by Engelke et al. [J. Chem. Phys. 1994, 101 (9), 7262] were used to extract the adsorption and desorption rate constants and the apparent sticking coefficient. The sticking coefficients of hydrogen measured at 333 K at a surface coverage of 0.4 over 5% ...
Mechanism Studies on CVD of Boron Carbide from a Gas Mixture of BCl3, CH4, and H-2 in a Dual Impinging-jet Reactor Karaman, Mustafa; Sezgi, Naime Aslı; Doğu, Timur; Ozbelge, Hilmi Onder (2009-03-01) Nearly pure boron carbide free from impurities was produced on a tungsten substrate in a dual impinging-jet chemical vapor deposition reactor from a BCl3, CH4, and H-2 mixture. The Fourier Tran form Infrared (FTIR) analysis proved the formation Of reaction intermediate BHCl2, which is proposed to occur mainly in the gaseous boundary layer next to the substrate surface. Among a large number of reaction mechanisms proposed only the ones considering the molecular adsorption of boron carbide on the substrate su...
