Performance comparison of microwave and conventionally heated reactors for sorption enhanced reforming of ethanol over Ni impregnated SBA-15
Sarıyer, Merve; Sezgi, Naime Aslı; Doğu, Timur (2019-12-01)
Hydrogen production from steam reforming of ethanol (SRE) and sorption enhanced steam reforming of ethanol (SESRE) over nickel impregnated SBA-15 catalyst was investigated in both conventionally and microwave heated reactor systems. Characterization results showed that 10 wt% Ni loaded SBA-15 exhibited Type IV isotherm with H1 hysteresis, which indicates mesoporous structure. Its surface area and mean pore diameter values were 493 m(2)/g and 6.5 nm, respectively. Results obtained in SRE tests showed high ac...
Effect of calcination/reduction temperature of Ni impregnated CeO2-ZrO2 catalysts on hydrogen yield and coke minimization in low temperature reforming of ethanol
ARSLAN KELAM, ARZU; Doğu, Timur (2016-10-15)
CeO2-ZrO2 was proven to be a quite effective catalyst support for steam reforming of ethanol (SRE). In this study, properties of Ni impregnated mesoporous CeO2-ZrO2 catalysts of different compositions were optimized by changing the calcination/reduction temperature. Increase of calcination/reduction temperature from 400 degrees C to 650 degrees C caused significant decrease in surface area and redox ability of the catalysts, yielding higher coke formation and lower hydrogen yields. Results proved that, very...
Effect of W incorporation on the product distribution in steam reforming of bio-oil derived acetic acid over Ni based Zr-SBA-15 catalyst
Cakiryilmaz, Nurbanu; ARBAĞ, HÜSEYİN; OKTAR, NURAY; DOĞU, GÜLŞEN; Doğu, Timur (2018-02-15)
Zirconia incorporated SBA-15 type mesoporous material was synthesized following a one pot hydrothermal route, characterized and used as the catalyst support in the synthesis of Ni and bi-metallic Ni W based catalysts. Performances of these catalysts were tested in steam reforming of AcOH. Catalytic activity tests proved that the performances of SBA-15 and Zr-SBA-15 supported Ni based catalysts were highly stable and they also showed very high activity in steam reforming of acetic acid, giving complete conve...
Effects of synthesis route on the performance of mesoporous ceria-alumina and ceria-zirconia-alumina supported nickel catalysts in steam and autothermal reforming of diesel
Bozda, Arzu Arslan; Sezgi, Naime Aslı; Doğu, Timur (2022-01-01)
Decline in catalyst performance due to coke deposition is the main problem in diesel steam (SR) and autothermal reforming (ATR) reactions. Good redox potential and strong interaction of CeO2 with nickel increase activity and coke resistivity of Ni/Al2O3 catalysts. In this study, mesoporous Al2O3, CeO2/Al2O3, and CeO2/ZrO2/Al2O3 supported nickel catalysts were successfully synthesized. The highest hydrogen yield, 97.7%, and almost no coke deposition were observed with CeO2/ZrO2/Al2O3 catalyst (Ni@8CeO(2)-2Zr...
Remote control of the diastereoselectivity in the pauson–khand reactions of chiral enynes
Sezer, Serdar; Tanyeli, Cihangir; Department of Chemistry (2011)
In this thesis, an intramolecular Pauson-Khand reaction of chiral enynes derived from homoallyl, allyl and homopropargyl alcohols is described. For this purpose, 2-heteroaryl substituted homoallyl, allyl and homopropargyl alcohols are easily and efficiently resolved through enzymatic resolution in a high ee (91-99%) with a known stereochemistry. Each enantiomerically enriched enyne derived from homoallyl and homopropargyl alcohols affords the conformationally most stable diastereomeric cyclopenta[c]pyran ri...
