Abstract: OLEFINS ARE OLIGOMERIZED BY BRINGING AT LEAST ONE C2 TO C8-OLEFIN INTO CONTACT WITH A NICKEL-CONTAINING HETEROGENEOUS CATALYST. THE CATALYST IS CONDITIONED BEFORE CONTACT WITH THE OLEFIN BY PASSING AN INERT GAS FLOW OVER THE SAME, UNTIL THE INERT GAS FLOW HAS A WATER CONTENT OF LESS THAN 1000 PPM. SELECTIVITY FOR THE PRODUCTION OF HIGHER OLIGOMERS, IN PARTICULAR TRIMERS RELATIVE TO THE FORMATION OF DIMERS IS INCREASED BY THE PRETREATMENT.
