Abstract: A process for the production of essentially unsaturated oligomers of 4-6C alkenes from an alkene or alkene containing hydrocarbon stream at a nickel containing heterogeneous catalyst in an adiabatic reactor at 20-300 [deg]C and 1-100 bar comprises working up a first partial outlet stream to the oligomer and recycling a second partial stream together with fresh alkene to the reactor.

Abstract: Procedimiento para la obtención de oligómeros de alquenos esencialmente no ramificados con 4 a 6 átomos de carbono, partiendo de los alquenos o de una corriente de hidrocarburos que contiene alquenos de este tipo en un catalizador heterogéneo que contiene níquel en un reactor accionado adiabáticamente a temperaturas desde 20 hasta 300ºC y a presiones de 1 a 100 bar, caracterizado porque se elabora una primera corriente parcial de la descarga del reactor a los oligómeros y se reconduce la segunda corriente parcial conjuntamente con alqueno fresco o una corriente de hidrocarburos fresca, que contiene alquenos de este tipo, al reactor.
