Disclosed is a new polyolefin catalyst and preparation therefor. Specifically, disclosed is a catalytic system comprising a new complex of iron, cobalt, nickel, palladium, and platinum. In the presence of the catalytic system, oily polyethylene can be efficiently obtained from simple olefins such as ethylene under mild conditions, highly branched oily alkane mixture is then obtained after hydrogenation. The alkane mixture can be used as a processing aid and a high-performance lubricant base oil. The present invention also provides a method for preparing the catalyst, a method for preparing the highly branched oily alkane mixture and a method for preparing functional polyolefin oil.
本发明公开了一种新型聚烯烃催化剂及其制备方法。具体地说,公开了一种由
铁、
钴、
镍、
钯和
铂的新型复合物组成的催化体系。在该催化体系存在的情况下,可在温和条件下从简单烯烃(如
乙烯)中有效地获得含油聚
乙烯,然后在氢化后获得高支链含油
烷烃混合物。
烷烃混合物可用作加工助剂和高性能润滑油基础油。本发明还提供了催化剂的制备方法、高支链油性
