Syngas from CO2 Reforming of Coke Oven Gas: synergetic effect of activated carbon / Ni-γAl2O3 Catalyst

The CO2 reforming of coke oven gas for the production of synthesis gas has been studied over an activated carbon, an in-lab prepared Ni/Al2O3 catalyst and physical mixtures of both materials in different proportions (AC+Ni) at 800 oC. It was found that there are two possible coexisting reaction pathways: the direct dry reforming of methane (decomposition of methane followed by gasification of t...

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...

Electrodeposited Re-promoted Ni foams as a catalyst for the dry reforming of methane

Article history: Received 11 October 2015 Received in revised form 2 December 2015 Accepted 15 December 2015 Available online 17 December 2015 The dry reforming of methane (DRM) utilizes carbon dioxide (CO2) as the oxidizing agent in order to produce synthesis gas. Catalyst deactivation via coking, oxidation, and sintering has stymied the industrialization of catalysts for the DRM. Here, we uti...

Nucleation and reshaping thermodynamics of Ni as catalyst of carbon nanotubes

A quantitative model describing the nucleation, energy, and diffusion restraints in reshaping of Ni nanoparticles as a catalyst of carbon nanotubes is developed by introducing the size-dependent thermodynamic quantities in the classical nucleation theory and the diffusion laws. The result from our model calculations is in good agreement with that of the latest time-resolved, high-resolution in ...
