Olefins production by catalytic partial oxidation of ethane and propane over Pt/LaMnO3 catalyst

Ethylene + acetylene yields exceeding 68% with selectivities above 80% are obtained over novel doped Pt/LaMnO3 catalysts under self-sustained ethane CPO at short contact time. Insights are presented on the impact of catalyst dopants and type of sacrificial fuel (CH4, CO, H2). The study on the novel catalysts is extended to ethylene and propylene production via CPO of propane. Results of an economic analysis for ethylene production from ethane in a 1MtA plant are presented, comparing the traditional steam cracking with CPO technology based on the best achieved experimental data with the Pt/LaMnO3 catalyst.
