Experimental Study on Dry Reforming of Biogas for Syngas Production over Ni-Based Catalysts.

ABSTRACT: Syngas production from dry reforming of biogas (DRB) is studied experimentally in this work. Ni/Al₂O₃, Pt/Al₂O₃, and Pt-Ni/Al₂O₃ are used as catalysts to examine the effect of CO₂ content in biogas and H₂O addition on DRB performance for reaction temperatures in the 600-800 °C range. It is found that the bimetallic Pt-Ni catalyst exhibits the best activity and thermal stability among the three types of catalysts studied due to better carbon deposition resistance. Because CO₂ functions as the oxidant in combustion, CH₄ conversion is enhanced when the biogas contains more CO₂. One hundred percent CO₂ conversion can be reached for biogas containing a less amount
