  • Publication number: 20200369965
    Abstract: Olefins are made by passing a cracker stream through a convection section of a cracker furnace; introducing steam and a stream comprising a recycle content pyrolysis oil into the cracker stream to form a combined stream, and the steam, r-pyoil stream, or both are introduced downstream of the inlet to the convection section, such as between the inlet to the coils and the radiant zone, or at the cross-over. Additionally, dilution steam can be added to a stream of r-pyrolysis to form a steam-diluted r-pyoil stream which is then introduced into a cracker furnace at any location, such as downstream of the inlets to the convection box or at a cross-over.

    Abstract: A cracker stream is provided that contains a recycle content pyrolysis oil composition, a predominantly C5 to C22 hydrocarbon composition, and steam at a steam-to-hydrocarbon ratio of at least 0.60:1. The method for making olefins includes: (a) combining a predominantly C5 to C22 hydrocarbon stream with a recycle content pyrolysis oil composition (r-pyoil) to provide a combined cracker stream; and (b) cracking the combined cracker stream in a cracker furnace to provide an olefin-containing effluent stream, wherein the combined cracker stream contains steam at a steam-to-hydrocarbon ratio greater than 0.60:1. There is also provided a cracker stream including r-pyoil), a predominantly C2 to C4 hydrocarbon composition, and steam at a steam-to-hydrocarbon ratio of at least 0.20:1. Olefins can be made from this cracker stream as well.

  • Patent number: 10837947
    Abstract: Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.
