Claims16
A process to oligomerize olefins under effective olefin oligomerization conditions in the presence of a homogeneous olefin oligomerization catalyst system comprising contacting said catalyst system with an olefin in a solvent;
- wherein said catalyst system comprises
- a) a chromium source selected from the group consisting of chromium metal and a chromium salt having the formula CrX.sub.n, wherein X can be the same or different and is an organic or inorganic radical and n is an integer from 1 to 6;
- b) a pyrrole-containing compound;
- and
- c) an alkyl compound;
- and
- wherein said solvent consists essentially of a product of said olefin oligomerization process.
A process to oligomerize olefins under effective olefin oligomerization conditions in the presence of a homogeneous olefin oligomerization catalyst system consisting essentially of contacting said catalyst system with an olefin in a solvent;
- wherein said catalyst system comprises a chromium source selected from the group consisting of chromium metal and a chromium salt having the formula CrX.sub.n, wherein X can be the same or different and is an organic or inorganic radical and n is an integer from 1 to 6, a pyrrole-containing compound that will react with the chromium source to form a chromium-pyrrolide complex and an alkyl compound;
- and
- wherein said solvent consists essentially of a product of said olefin oligomerization process.
