  • Polyolefin catalyst and use thereof
    Patent number: 10961329
    Abstract: 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.
    Type: Grant

  • Catalytic system for preparation of high branched alkane from olefins
    Patent number: 10294440
    Abstract: The present invention discloses a catalytic system for preparing highly branched alkane from olefin, which contains novel nickel or palladium complexes. In the presence of the catalytic system, highly branched oily alkane mixture can be efficiently obtained from olefins (such as ethylene) under mild conditions. The alkane mixture has a low bromine number, and can be used as a processing aid(s) and lubricant base oil with high-performance. Provides also was a method for preparing the catalyst and a method for preparing an oily olefin polymer.
