Beschreibung
Zusammenfassung:	The invention relates to a solid catalyst system comprising a chromium compound, an aluminium alkoxide compound, a nitrogen containing compound and a silicon oxide support, wherein the aluminium alkoxide compound has the formula (R1)2-Al-OR2 wherein R1 is selected from C1-C8 alkyl groups and OR2 is selected from C1-C8 alkoxyl groups and wherein the nitrogen containing compound is a cycloalkylamine compound having the general formula: R3-NH2, wherein R3 is selected from C3-C8 cycloalkyl groups. L'invention concerne un système catalyseur solide comprenant un composé de chrome, un composé alcoxyde d'aluminium, un composé contenant de l'azote et un support d'oxyde de silicium, le composé alcoxyde d'aluminium ayant la formule (R1)2-Al-OR2 dans laquelle R1 est sélectionné parmi des groupes alkyle en C1-C8 et OR2 est sélectionné parmi des groupes alcoxy en C1-C8 et le composé contenant de l'azote étant un composé cycloalkylamine ayant la formule générale : R3-NH2, dans laquelle R3 est sélectionné parmi des groupes cycloalkyle en C3-C8.
