In this work, three catalysts (Ni-based catalyst, Ni/Fe-based catalyst, and Ni/Ce-based catalyst) were developed for catalytic cracking of toluene as a model compound of tar in a fixed bed reactor. The characteristic of catalysts were determined by XRD, EDX, and BET. Meanwhile, the effects of calcination temperature and reaction temperature on syngas yield and toluene conversion rate were also studied. The results showed that the BET surface area was decreased with the rise of calcination temperature, while the content of hydrogen and syngas yield were decreased with the rise of calcination te...
