Summary:This disclosure provides for new catalyst systems and new methods for preparing and using the catalyst systems for generating a trimerization product. In an aspect, the new catalyst systems comprise a chromium carboxylate that is prepared by anhydrous metathesis. In another aspect, the catalyst system comprise a chromium carboxylate that is prepared by anhydrous metathesis and a metal pyrrolide compound. The catalyst systems imparts improved performance and/or reduced catalyst system cost to an olefin trimerization process. La présente invention concerne de nouveaux systèmes catalytiques et de nouveaux procédés de préparation et d'utilisation des systèmes catalytiques pour produire un produit de trimérisation. Selon un aspect, les nouveaux systèmes catalytiques comprennent un carboxylate de chrome préparé par métathèse anhydre. Selon un autre aspect, le système catalytique comprend un carboxylate de chrome préparé par métathèse anhydre et un composé pyrrolide de métal. Les systèmes catalytiques confèrent des performances améliorées et/ou un coût de système catalytique réduit à un procédé de trimérisation d'oléfines.
