  • Patent number: 10221263
    Abstract: A catalyst system for polymerizing olefin-based polymers and interpolymers is disclosed. The catalyst system may include a supported chromium catalyst and a Ziegler-Natta catalyst comprising a bulking agent, Mg, and Ti. The Ziegler-Natta catalysts in catalyst systems disclosed herein run exceptionally well without addition of excessive amounts of co-catalyst, thus allowing for use of chromium based supported catalysts that would otherwise be overwhelmed by aluminum alkyl. Further, embodiments disclosed herein may be run without an internal electron donor, and the lack of an internal electron donor in the system also prevents poisoning of the chromium catalysts by the internal electron donor. By including or co-feeding a chromium based catalyst with these Ziegler-Natta catalysts, it has been found that the molecular architecture of the resulting polyolefins, such as polyethylenes, may provide for resins with excellent processing properties.

  • Patent number: 8785340
    Abstract: The catalyst exhibiting hydrogen spillover effect relates to the composition of a catalyst exhibiting hydrogen spillover effect and to a process for preparing the catalyst. The catalyst has a reduced transition base metal of Group VIB or Group VIIIB, such as cobalt, nickel, molybdenum or tungsten, supported on a high porous carrier, such as saponite, the base metal being ion-exchanged with at least one precious metal of Group VIIIB. The process includes the steps of loading the base metal onto the support, reducing the base metal, preferably with H2 at 600° C., and thereafter ion-exchanging the precious metal with the base metal. Preferred examples of the catalyst include a saponite support loaded with about 10-20 wt % cobalt and about 0.1-1 wt % precious metal. The catalyst is optimized for reactions that occur in commercial processes at about 360-400° C., such as in hydrocracking.
