  • Compatibilization of post consumer resins
    Patent number: 11753534
    Abstract: Compositions comprising post-consumer recycled (PCR) waste are described. The PCR is combined with at least one virgin resin and a propylene-based compatibilizer that enhances the blend between the PCR and virgin resin as well as improving one or more physical properties of the composition. The propylene-based compatibilizer is a reactor made thermoplastic polyolefin or a heterophasic copolymer with a semi-crystalline matrix and a rubber component. This allows for the selection of a compatibilizer that can shift the composition's physical properties based on the end use application, and provide a stronger, miscible blend.

  • Methods of treatment and use of spent equilibrium catalyst
    Patent number: 10946371
    Abstract: Disclosed is a method of treating spent equilibrium catalyst (ECAT) for reuse, in which a quantity of spent ECAT comprising hydrophilic particles with differing levels of metal contamination is disposed into a reactor and treated to form carbon nanotubes on the particles having metal contamination, thereby rendering at least a portion of the spent ECAT particles hydrophobic; the hydrophobic particles can then be separated from the hydrophilic particles. Also disclosed is a method of remediating an oil spill using a carbon nanotube sponge material.
