  • Patent number: 8377386
    Abstract: Flow deflector that is capable of changing the flow direction of a fluid during passage through a duct. The duct is formed by an inner and outer duct, which creates an annular region in the duct. The flow deflector forces the fluid passing through the annular region of the duct to flow inside the inner duct, while the fluid passing through the inner duct is forced to flow through the annular region. Reactor tubes for catalytic reactors are formed by assembling tubes comprising said flow deflector and having a catalyst arranged in the inner tube.

  • Patent number: 8366909
    Abstract: Processes for reforming of naphtha feedstocks are described. Briefly, a two stage naphtha reforming process is described. The first stage uses a low acidity beta zeolite catalyst under relatively mild reforming conditions to form an effluent. This effluent is passed to a subsequent stage where further reforming occurs using a catalyst containing ZSM-5 zeolite. The second stage is run under mild reforming conditions. The low pressures employed in the reforming process described maximize liquid product yield by avoiding unwanted cracking reactions and production of light products.

  • Patent number: 8313641
    Abstract: The service life and deactivation rate of a reforming catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water causing process upsets in a catalytic reforming process is practically eliminated. The fact that the guard bed material preserves the active metal phase—copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product.

    Abstract: Apparatuses and methods are disclosed for contacting radially flowing fluids with solid particles (e.g., catalyst) with reduced tendency for fluidization of the particles, and especially a sealing portion of the particles at the top of a particle retention zone disposed between screens at upstream and downstream positions relative to radial fluid flow. Fluidization is reduced or eliminated by offsetting openings of the screens in the axial direction, such that upstream openings in the upstream screen are above highest downstream openings in a downstream stream. The offset in openings imparts a downward flow component to radially flowing fluid, thereby reducing solid particle fluidization without the need to induce a specific pressure drop profile along the entire axial direction of the screens.

    Abstract: A system and method for recycling plastics. The system and method recover materials such as hydrocarbon gases, liquid hydrocarbon distillates, various polymers and/or monomers used to produce the original plastics. The system and method allow about one unit of input of energy input to the plastic recycler to be used to create one or more gaseous components and one or more liquid distillate components from a plastic that is being recycled. The one or more gaseous components and one or more liquid distillate components produce about one corresponding unit of useable output energy recovered from the recycling of the plastic.
