Description
【請求項8】
前記ガス混合物中の触媒毒の百分率が、10 -3 重量%以下であり、かつ該ガス混合物から除去される触媒毒が二酸化硫黄であることを特徴とする請求項1から7いずれか記載の方法。
前記ガス混合物中の触媒毒の百分率が、10 -3 重量%以下であり、かつ該ガス混合物から除去される触媒毒が二酸化硫黄であることを特徴とする請求項1から7いずれか記載の方法。
本発明の方法は、メタロセンまたはクロム/シリカゲル触媒が使用されるならば特に適しており、その理由はこれらの触媒が触媒毒に特に鋭敏であるからである。これらの触媒毒は、実際に同定することがしばしば不可能であるので、極めて少量の不純物、ppmレベルでさえ、できうる限り完全に除去することが特に重要である。一般に、ガス混合物中の触媒毒の割合は、10 -3 重量%より小さい。
