    摘要： Process for producing alpha olefins comprising contacting ethylene, a zirconium based catalyst system comprising, a hydrocarbylmetal compound, a chain transfer agent, and optionally an organic reaction medium. Chain transfer agents which can be utilized include a) hydrogen, b) a compound comprising a hydrogen silicon bond, a compound having a hydrogen sulfur bond, a compound having a hydrogen phosphorus bond, or c) a transition metal compound chain transfer agent.

    摘要： Disclosed herein is a process for forming an oligomer product comprising (a) introducing into a reaction zone (i) ethylene; (ii) a heteroatomic ligand metal salt complex comprising a heteroatomic ligand complexed to a first metal salt; (iii) a second metal salt wherein an equivalent molar ratio of the second metal salt to the heteroatomic ligand of the heteroatomic ligand metal salt complex is at least 0.5:1 and where the second metal salt is an iron salt, a cobalt salt, or any combination thereof; (iv) an organoaluminum compound; and (b) forming an oligomer product. Also disclosed herein is a process comprising (a) introducing into a reaction zone (i) ethylene; (ii) a heteroatomic ligand; (iii) a metal salt where an equivalent molar ratio of the metal salt to the heteroatomic ligand is at least 1.5:1; (iv) an organoaluminum compound; and (b) forming an oligomer product.
