    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.
