Title:
【発明の名称】オレフィンの三量化のための触媒および方法
Document Type and Number:
Japanese Patent JP2002532249
Kind Code:
A
Abstract:
A process is provided to modify an olefin production catalyst system which comprises contacting an olefin production catalyst system with ethylene prior to use. A second embodiment of the invention comprises contacting an aluminum alkyl and a pyrrole-containing compound prior to contacting a chromium containing compound and prior to contacting an olefin. A process also is provided to trimerize and/or oligomerize olefins with the novel, modified olefin catalyst production systems. These modified olefin production catalyst systems can produce less solids, such as, for example, polymer, during a trimerization reaction.
