The effect of preparation route of commercial Co/γ-Al2O3 catalyst on important Fischer-Tropsch kinetic parameters studied by SSITKA and CO-DRIFTS transient hydrogenation techniques
Vasiliades, M. A.; Kalamaras, C. M.; Govender, N. S.; Govender, A.; Efstathiou, Angelos M. (2019)Two commercial Co-based catalysts supported on carbon-coated and uncoated γ-Al2O3 (during Co deposition) of different Co particle size (∼7 and 10 nm) and surface structure were investigated to address the effect of preparation ...

The effect of Pt on the carbon pathways in the dry reforming of methane over Ni-Pt/Ce0.8Pr0.2O2-δ catalyst
Vasiliades, M. A.; Damaskinos, C. M.; Kyprianou, K. K.; Kollia, M.; Efstathiou, Angelos M. (2019)The present work extensively discusses the carbon pathways in the dry reforming of methane with carbon dioxide (DRM) at 750 °C towards syngas (CO/H2 ˜ 1) over 5 wt% Ni, 0.5 wt% Pt and their bimetallic alloy (5 wt% Ni-0.5 wt% ...

Origin and reactivity of active and inactive carbon formed during DRM over Ni/Ce0.38Zr0.62O2-δ studied by transient isotopic techniques
Vasiliades, M. A.; Djinović, P.; Davlyatova, L. F.; Pintar, A.; Efstathiou, Angelos M. (2018)The role of Ce0.38Zr0.62O2-δ redox support and that of reactants CH4 and CO2 in the carbon-path of dry reforming of methane (DRM) at 750°C over a 3wt% Ni/Ce0.38Zr0.62O2-δ catalyst were investigated. In particular, meticulously ...
