PRODUCTION OF ETHYLENE AND PROPYLENE FROM ETHANE, …
ABSTRACT We studied the production of ethylene (C2") and propylene (C3") by the decomposition of pure ethane, propane, and n-butane, mixed with steam, in a microwave-irradiated fixed bed reactor packed with silicon carbide. We found that ethylene production was maximized using ethane as the feed, with per pass yields as high as 63% at an ethane conversion level of 74%.
