Abstract: The invention relates to a method for oligomerising C2- to C8 olefins on a heterogeneous catalyst containing nickel. Said method comprises the following steps: i) a catalyst pre-treatment phase in which the catalyst is brought into contact with a first hydrocarbon mixture which has an olefin content of less than 50 wt. % and contains less than 0.1 wt. % diolefins and alkines; and ii) an essentially stationary working phase in which a stream of a second hydrocarbon mixture, which contains 50 to 100 wt. % C2- to C8 olefins and less than 10 wt. ppm diolefins and alkines, is brought into contact with the catalyst.

Abstract: The invention relates to a method for producing essentially unbranched octenes and dodecenes by oligomerising flows of hydrocarbons containing butene-1 and/or butene-2 and butane, said hydrocarbon flows being essentially free of isobutene, at temperatures of 30 to 280 DEG C and at a pressure of 10 to 300 bar over a heterogenous catalyst containing nickel. According to the invention, sufficient quantities of the butane which has separated from the reaction mixture and sufficient quantities of non-reacted butene are reintroduced into the oligomerisation reaction to ensure that the maximum quantity of oligomers contained in the reacted reaction mixture does not exceed 25 wt. % in any part of the reactor or if a reactor cascade is used, in any part of the cascade.

Abstract: IN A PROCESS FOR PREPARING ESSENTIALLY UNBRANCHED OCTENES AND DODECENES BY OLIGOMERIZATION OF HYDROCARBON STREAMS WHICH COMPRISE 1—BUTENE AND/OR 2—BUTENE AND BUTANE AND ARE ESSENTIALLY FREE OF ISOBUTENE, AT FROM 30 TO 280°C AND A PRESSURE OF FROM 10 TO 300 BAR OVER A NICKEL—CONTAINING HETEROGENEOUS CATALYST, THE BUTANE AND UNREACTED BUTENE SEPARATED FROM THE REACTION MIXTURE ARE RECIRCULATED TO THE OLIGOMERIZATION REACTION IN SUCH AMOUNTS THAT THE MAXIMUM CONTENT OF OLIGOMERS IN THE CONVERTED REACTION MIXTURE DOES NOT EXCEED 25 % BY WEIGHT AT ANY POINT IN THE REACTOR OR, IF A REACTOR CASCADE IS USED, AT ANY POINT OF THE REACTOR CASCADE.
