Process for preparing proylene and 1-butene |
摘要 |
Preparation of propene and optionally 1-butene comprises converting butene isomers to propene isomers using metathesis catalyst and converting formed 2-pentene to propene and 1-butene, isolating and recycling the 2-butene fraction. Preparation of propene and optionally 1-butene comprises: (a) converting 1-butene and 2-butene in the presence of a metathesis catalyst containing group VIb, VIIb or VIII metals; (b) removing propene and 2-pentene formed; (c) converting the 2-pentene using ethene to propene and 1-butene in the presence of the metathesis catalyst in (a); (d) removing propene and 1-butene formed; and (e) discharging the 1-butene and partially isomerizing 1-butene to 2-butene in the presence of a catalyst and recycling the 1-butene and 2-butene with a part of the unreacted 4C-fraction from (a) to (a). An Independent claim is also included for the apparatus for carrying out the preparation of propene and 1-butene comprising a metathesis reactor (R01) connected to a distillation column (K101) for removing 2/3C low boiling, 4C middle boiling and 5C+ high boiling phases; column (K301) for removing ethene and propene; and reactor (R02) for reacting 2-pentene with ethene. |
