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 CH4:CO2 ratio was observed to be 1:2 (with or without O2 presenting).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
