Abstract
Separation of ethylene from ethane is achieved by feeding a mixture of the C hydrocarbons in contact with a CTS-1 crystalline titanium silicate molecular sieve which has a controlled pore size to selectively adsorb ethylene and size exclude ethane. The feed stream can also contain acetylene which can be selectively adsorbed from both ethane and ethylene by further controlling the pore size of the CTS-1 molecular sieve. Propane/propylene separation is also disclosed.
