Potential of Ni supported on clinoptilolite catalysts for carbon dioxide reforming of methane

Activity of different zeolite-supported Ni catalysts for methane reforming with carbon dioxide

“…Based on our earlier work, the potential of zeolites clinoptiolite [19], KH [20], and KL [21], for the CO 2 reforming of CH 4 were reported as good candidates based on their high activity and stability compared to an Al 2 O 3 support. The effects of Ni loading and promoter on the catalytic behavior were investigated and stability testing was also done.…”

A Short Review on the Catalytic Activity of Hydrotalcite-Derived Materials for Dry Reforming of Methane

“…Moreover, deactivation is substantially accelerated as a consequence of carbon deposition, since carbon-forming reactions are thermodynamically favoured in the same temperature window and proceed more easily on large nickel crystallites [21]. Several approaches have been therefore proposed in order to increase the stability of Ni-based catalysts [22] [37]); zeolites (zeolite Y, zeolite A, zeolite X, ZSM-5) [38]; clays (clinoptolite [39], diatomite [40], vermiculite [41], montmorlonite [42]); and carbon-based materials (carbon nanotubes, activated carbon) [43].…”

Zeolite-supported Ni catalyst for methane reforming with carbon dioxide

“…Recently, the activity of different zeolite-supported Ni catalysts for methane reforming with carbon dioxide has been investigated [10,11]. Among these, MFI-and USY-type zeolites greatly improve both the activity and the selectivity of the reaction because of their suitable properties as supports for catalysts in reforming reactions, such as their microporous structure, high surface area and high affinity for CO 2 adsorption [12,13]. Chang et al found that Ni supported on pentasil zeolite (ZSM-5 Si/Al [ 200) showed high activity with high resistence to coke formation during CO 2 reforming of methane [14].…”
