Process for producing ethylene by chlorination of ethane and dehydrochlorination of ethyl chloride |
| 摘要 |
Ethylene is produced from ethane in three steps: first, ethane is oxychlorinated to produce ethyl chloride and water; second, ethyl chloride from the first step is cracked to produce ethylene and hydrogen chloride; and third, the hydrogen chloride from the second step is recycled to the front step. |

1. A process for the manufacture of ethylene from ethane comprising the steps of:
a) oxychlorinating ethane with hydrogen chloride and oxygen to give ethyl chloride and water at a temperature in the range of 350° to 400° C. in the presence of a catalyst; b) vapor phase cracking the ethyl chloride to give ethylene and hydrogen chloride at a temperature in the range of 325° to 375° C. over a catalyst consisting of silica alumina; and c) recycling hydrogen chloride produced in step b for use in step a. |
