Autothermal oxidative coupling of methane (OCM) is a highly attractive approach for methane utilization. If platinum-based catalysts are operated in short-contact-time reactors with high space velocities, high methane conversion can be achieved. Using a 1 wt.% Pt/Al₂O₃ catalyst as a benchmark, the present study elucidates how different dopants, namely Ni, Sn, and V₂O₅, affect the OCM reaction. Kinetic catalyst tests reveal that acetylene (C₂H₂) is the predominant C₂ product, irrespective of the catalyst formulation or operation conditions. Furthermore, the use of bimetallic catalysts allows either for the maintenance or even the improvement of the C₂ selectivity during OCM, which is attributed to synergistic effects that occur when expensive Pt is partially replaced by cheaper dopants. In particular, the 1 wt.% Pt/Al₂O₃ reference catalyst yielded a maximum C₂ selectivity of 8.2%, whereas the best-performing doped sample 0.25 wt.% Pt 0.75 wt.% V₂O₅/Al₂O₃ yielded a total C₂ selectivity of 11.3%.
