| titleOfInvention | ISOBUTEN PRODUCTION OF ELEVADA PURITY AND PROPYLENE FROM HYDROCARBON FRACTIONS WITH FOUR CARBON ATOMS. |
| abstract | Process for converting a C4 olefinic fraction into high purity isobutene and propylene, said fraction containing mainly diolefins, butene-1, butenes-2, isobutene and acetylenic impurities, said process comprising the following steps, successively developing: 1) hydrogenation Selective diolefins and acetylenic impurities with isomerization of butene-1 in butenes-2 in the presence of a catalyst, to obtain an effluent containing n-butenes, whose ratio corresponds to thermodynamic and isobutene equilibrium, and which does not contain practically diolefins or acetylenic compounds; 2) the separation, by distillation, of a head fraction containing isobutene and a tail fraction containing essentially butenes-2 and butane; and 3) the metathesis of the butenes-2 fraction from the preceding stage with ethylene, in the presence of a catalyst, to obtain an effluent containing propylene, the metathesis being followed by a separation of the propylene, said process being characterized in that the stage 2 is performed on a column that integrates the hydro- |
