Preparation of ethylene by gas permeation |
| abstract |
The present invention relates to a process for the production of olefins comprising the steps of oxidizing olefins in a reactor to form a reaction gas mixture comprising unoxidized olefins and separating the unoxidized olefins partially or totally from the reaction gas mixture by a membrane process, And a process for preparing a carbonyl compound from an oxidizing agent. |
