Ceria promoted NOx storage and reduction materials

Say, Zafer (Bilkent University, 2011)

In the current work, the effect of CeO2 promotion on the NOx storage materials and NOx storage-reduction (NSR) catalysts is studied. Synthesized materials were prepared using different baria and ceria loadings in order ...

Dry reforming of glycerol over Rh-based ceria and zirconia catalysts: New insights on catalyst activity and stability

Bulutoğlu, P. S.; Say, Zafer; Bac, S.; Özensoy, Emrah; Avcı, A. K. (Elsevier B.V., 2018)

Effects of reaction temperature and feed composition on reactant conversion, product distribution and catalytic stability were investigated on syngas production by reforming of glycerol, a renewable waste, with CO2 on ...

Exceptionally active and stable catalysts for CO2 reforming of glycerol to syngas

Bac, S.; Say, Zafer; Koçak, Yusuf; Ercan, Kerem E.; Harfouche, M.; Özensoy, Emrah; Avcı, A. K. (Elsevier, 2019)

CO2 reforming of glycerol to syngas was studied on Al2O3-ZrO2-TiO2 (AZT) supported Rh, Ni and Co catalysts within 600–750 °C and a molar inlet CO2/glycerol ratio (CO2/G) of 1–4. Glycerol and CO2 conversions decreased in ...

Investigation of NO2 and SO2 adsorption/desorption properties of advanced ternary and quaternary mixed oxides for DENOx catalysis

Say, Zafer (Bilkent University, 2015-11)

The main premise of the current study is the design, synthesis and functional characterization of novel catalytic materials with superior resistance against sulfur poisoning without compromising NOx storage capacity (NSC) ...

Trade-off between NOx storage capacity and sulfur tolerance on Al2O3/ZrO2/TiO2–based DeNOx catalysts

Say, Zafer; Mihai, O.; Kurt, Merve; Olsson, L.; Özensoy, Emrah (Elsevier, 2019)

Al2O3/ZrO2/TiO2 (AZT) ternary mixed oxides functionalized with Pt and BaO were synthesized in powder and monolithic forms and were utilized in NOx Storage Reduction/Lean NOx Trap (NSR/LNT) catalysis as novel catalytic ...
