Effect of cobalt loading on suppression of carbon formation in carbon dioxide reforming of methane over Co/MgO catalyst

Recent Progress of Catalyst Design for Carbon Dioxide Reforming of Methane to Syngas

“…Co size of good distribution was observed over the catalysts with lower Co content [56] . The size of Co increased with the increase of Co loading [56] .…”

“…Co size of good distribution was observed over the catalysts with lower Co content [56] . The size of Co increased with the increase of Co loading [56] . With the increase of Co loading over Co/MgO catalyst from 10 mol% to 25 mol%, the rate of carbon deposition increased from 0.0016 gc/gcat h -1 to 0.2227 gc/gcat h -1 .…”

“…Reducing the size of Co nanoparticles is feasible for improving its anti-carbon deposition capacity and improving the stability. Mohamed et al explored the size effect of Co on the anti-carbon deposition capacity and stability of the catalysts in CO 2 reforming of CH 4 [56] .…”

“…With the increase of Co loading over Co/MgO catalyst from 10 mol% to 25 mol%, the rate of carbon deposition increased from 0.0016 gc/gcat h -1 to 0.2227 gc/gcat h -1 . The reason for the larger amount of carbon formation over larger sized Co nanoparticles might be due to the weak interaction between Co and support MgO [56] .…”

Development of Co Supported on Co−Al Spinel Catalysts from Exsolution of Amorphous Co−Al Oxides for Carbon Dioxide Reforming of Methane

“…Alternatively, it has been revealed that the supported Co catalysts show good activity for dry reforming process. [9,[12][13][14][15] Even though the catalytic activity is neither superior to Ni nor to other noble metal catalysts such as Ru and Rh, studies on the supported Co catalysts have reported to produce good catalytic performance with significantly lower carbon deposition. [16,17] Previous study suggested that the rate of carbon deposition and the type of deposited carbon on Co metal are different from that on Ni metal.…”
