131Catalytic Reforming of Biogas into Syngas Using Supported Catalysts
Zhang et al. [16] assigned improved carbon resistance of supported bimetallic
NiCo catalysts, compared with monometallic nickel ones, to good metal dispersion,
high metallic surface area, solid solution formation, and SMSIs.
The specic carbon accumulation rates over supported monometallic and bime-
tallic Ni/CeZr, Co/CeZr, and NiCo/CeZr catalysts containing the total of 12 wt%
metals are compared in Figure 5.8. As can be seen, alloying nickel and cobalt in a
40:60 molar ratio leads to a substantial decrease of carbon accumulation rate.
In summary, considerable improvement of ...
