The production of propylene by the method of metabolism with low or no ethylene content includes the following steps: dividing a C4 hydrocarbonate stream into two parts, establishing a connection with two metabolic reaction areas, recovering part of ethylene, propylene, one or more C4 and at least one C5 and C6 oil.

摘要

Process for production of propylene fractionating which comprises a mixed Flow of C4 hydrocarbons, contacting a portion of the first fraction with a First Catalyst for metathesis, recover a effluent from the first reaction Zone, contacting at least a portion The Second fraction and at least a portion of the Ethylene in a Second reaction Zone.Retrieve an effluent of said Second Zone and split the effluent from the first reaction Zone and the effluent from the second reaction Zone; and a process for the production of propylene
