چکیده

Catalytic steam reforming of diesel fuel has the potential for producing syngas or hydrogen that can be feed to a cell (especially SOFC) portable power generation. Cost-effective, highly active catalysts with resistance towards carbon formation and sulfur poisoning are critically needed commercialize such technologies successfully. Thus in present work, we have explored CaO-Al2O3 based hydrotalcite structure derived catalyst precursors production via model compound (n-dodecane). The n-dodecane reactions was also carried out presence 100 ppm compounds at steam-to-carbon ratio 2. Among all tested, Co-CaO-Al2O3 gave best catalytic performance respect conversion, stability, suppression. At 700 °C, possesses > 90% conversions negligible (1.04 mg C/g.h) period 24 h. It is observed upon deactivation due poisoning, regenerated by simple thermal treatment 750 which considerably low decomposition temperature behavior CoSx CaS species formed this catalyst. Lower deposition over attributed better oxygen affinity Co higher normalized basicity than other catalysts.

Optimization of the preparation procedure of Ni/Al2O3 catalyst for steam reforming of n-butane

Performance of Ni/Al2O3 catalysts (10 wt.% Ni) in steam reforming of n-butane was investigated in terms of n-butane conversion, selectivity to hydrogen and hydrogen yield. The process was carried out in a fixed-bed tubular reactor at 650 °C and atmospheric pressure. The volumetric flow rates of n-butane and steam were 0.1 mL/min and 0.6 mL/min, respectively. The catalysts were prepared by preci...

Propene versus propane steam reforming for hydrogen production over Pd-based and Ni-based catalysts

Experiments of propane and propene steam reforming have been performed over a Pd–Cu/c-Al2O3 catalyst and over a Ni/NiAl2O4 catalyst. Over the palladium-based catalyst, the steam reforming of propene is faster and more selective than steam reforming of propane. Over the Pd catalyst, the steam reforming of propane is likely inhibited by site poisoning. In contrast, over Ni-based catalyst the refo...

Development of Ni-Based Catalysts Derived from Hydrotalcite-Like Compounds Precursors for Synthesis Gas Production via Methane or Ethanol Reforming

As a favorably clean fuel, syngas (synthesis gas) production has been the focus of concern in past decades. Substantial literatures reported the syngas production by various catalytic reforming reactions particularly in methane or ethanol reforming. Among the developed catalysts in these reforming processes, Ni-based catalysts from hydrotalcite-like compounds (HTLcs) precursors have drawn consi...

Kinetic comparison of Ni/Al2O3 and Ni/MgO-Al2O3 nano structure catalysts in CO2 reforming of methane

The kinetic characteristics of the Ni/Al2O3 and Ni/MgO-Al2O3 catalysts were investigated in CO2 reforming of methane (CRM). The reaction orders (α and β) and the rate constant (k) were calculated using the non-linear regression analysis, in which the sum of the squared differences of calculated and experimental CO2 reforming of m...
