Process for preparing ethene |
| abstract |
Process for the production of ethene by the vapor phased chemical dehydration of a feed containing ethanol, water and ethoxyethane in a reactor at elevated temperature and pressure in the presence of a bed of catalyst comprising a supported heteropolytungstic acid, by maintaining or configuring the reactor so that it operates in a regime which satisfies the following parameters:n n0.05<( P water /P ethanol +P ethoxyethane ))/(8×10 −5 ×GHSV+0.75) (1)n nandn n−20< T reaction −T dew point −40× P total feed +40× P inerts <+80 (2)n nwherein P water , P ethanol and P ethoxyethane , GHSV, T reaction , T dew point , P total feed and P inerts are as defined in the specification. |
