| titleOfInvention | Method for the production of propene by metathesis of c 4- to c 9- olefins |
| abstract | The invention relates to a method for the production of propene by multiple execution of the following sequence of steps, whereby in step 1 a mixture M1, essentially comprising unbranched C4- to C9 monoolefins (Components 04-9), 0 to 15 mol. % ethylene (component E), based on the components 04-9, 0 to 100 mol. % saturated hydrocarbons (components KG), based on the components 04-9, 0 to 30 mol. % olefins with more than 9 hydrocarbon atoms (components 0>9), based on components 04-9, 0 to 1 mol. %, based on the components 04-9, propene (component 03), 0 to 10 mol. %, based on the components 04-9, of other hydrocarbons (components KS), is brought into contact with a metathesis catalyst at a temperature of 20 to 350° C., with the proviso that the molar proportion of the sum of the 1-olefins and the sum of the 2-olefins to the sum of the components 04-9 and 0>9 is at least 0.5%, so long as the mixture M1 is not simultaneously or previously subjected to an isomerisation, correspondingly changing the proportion of 1- and 2-olefins, thus producing a mixture M2. In step II a mixture M1 is produced from a mixture M2 whereby a) propene and optionally components 0>9 and components KS are completely or partially removed and b) amounts of components 04-09 are added, a maximum of 1 mol. % of component E, based on the added amounts of components 04-09 and optionally other saturated or olefinically-unsaturated hydrocarbons, based on the added amounts of components 04-09, are added. |
