Abstract

La0.8Sr0.2Cr0.9Ni0.1O3 (LSCN) perovskite was calcined in hydrogen atmosphere (LSCN-H2) that provides better activity than LSCN-air. The doping of Au (as Au/LSCN-H2) improved the catalyst stability toward oxidativecoupling of methane (OCM) reaction by increasing the resistance of carbon formation on catalyst surface during the reaction. The suitable CH4:O2 ratio appeared to be 2:1, from which 5.8%, 29.9%, 8.1%, and 5.8% of C2H4, C2H6, C3H6, and C3H8 can be produced respectively. Importantly, the addition of CO2 can significantly promote the yield of C3H8 produced, from which the suitable CO2:CH4 ratio was observed to be 1:2 (with or without O2 presenting).
