HERSTELLUNGSVERFAHREN FUER ETHYLENOXID. |
摘要 |
A process for the preparation of ethylene oxide by reacting ethylene with molecular oxygen in the presence of a silver-containing catalyst, which comprises passing a gas mixture of ethylene and oxygen through a reaction zone containing the catalyst particles, while removing heat from the reaction zone by a cooling medium which flows through the reaction zone via one or more helical patterns, each pattern containing one or more helices. |
