    Abstract: Preparation of an ethene stream (C 2), a propene stream (C 3), an isobutene and optionally a 4C-olefin stream (C 4), a 2-methyl-2-butene and optionally 2-butene stream (C 5), and optionally other hydrocarbons containing stream (C x), optionally several separate components containing streams, comprises contacting a C4-hydrocarbon stream with ethene in a metathesis step; and separating the streams. Preparation of an ethene stream (C 2), a propene stream (C 3), an isobutene and optionally 4C olefin stream (C 4), a 2-methyl-2-butene and optionally 2-butene stream (C 5), and optionally other hydrocarbons containing stream (C x), optionally several separate components containing streams, comprises: (A) a metathesis step, in which a C4-hydrocarbon stream, containing at least 2-butene (15 wt.%), at least isobutene (5 wt.%) and 1-butene (less than 5 wt.%) (feed stream), is contacted with ethene in the presence of usual metathesis catalysts; and (B) separation of the streams (C2, C3, C4 and optionally Cx) from the obtained hydrocarbon stream, with the stream (C5) completely or partially led back to the metathesis step. Independent claims are included for methods for preparing feed stream, comprising subjecting naphtha or other hydrocarbon compounds to steam cracking or fluid catalytic cracking (FCC)-process, or dehydrating butane containing hydrocarbon stream and followed by purifying the obtained C4-olefin-mixture containing isobutene, 2-butene, butadiene, optionally butyne and optionally 1-butene, and removing the obtained stream of C4-olefin-mixture; and removing butadiene and butyne by means of selective hydrogenation to butene or butane hydride, or butadiene and butyne by extractive distillation of the obtained C4-olefin-mixture (raffinate I), where the content of 1,3-butadiene is at a maximum of 1000 wt. ppm.

    Abstract: A C4-olefin mixture having a 1,3-butadiene content of from 100 to 500 ppm and a content of 1,2-dienes of less than 10 ppm is described. The present invention further provides a process for preparing this C4-olefin mixture and provides for its use in a metathesis reaction for preparing 2-pentene and/or 3-hexene.

    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 DEG 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.
