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.

  • Patent number: 7771586
    Abstract: A strontium-doped, calcium-alumina nickel supported reforming catalyst is useful for reforming reactions when it is desired to generate a low H2/CO ratio synthesis gas and to reduce coking. The catalyst can generate a synthesis gas having a H2/CO ratio of less than about 2.3. The catalyst includes alumina, from about 0.3 wt. % to about 35 wt. % of calcium oxide, from about 0.1 wl % to about 35 wt. % of a strontium promoter, and about 0.5 wt. % to about 30 wt. % nickel. The support is prepared by a method wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.

  • Patent number: 7704379
    Abstract: The present invention relates to a process for converting Fischer-Tropsch wax to high quality lube basestocks using a molecular sieve Beta catalyst followed by a unidimensional intermediate pore molecular sieve with near circular pore structures having an average diameter of 0.50 nm to 0.65 nm wherein the difference between the maximum diameter and the minimum is ?0.05 nm. Both catalysts comprise one or more Group VIII metals. For example, a cascaded two-bed catalyst system consisting of a first bed Pt/Beta catalyst followed by a second bed Pt/ZSM-48 catalyst is highly selective for wax isomerization and lube hydrodewaxing with minimal gas formation.

    Abstract: One exemplary embodiment can include a method of altering a feed to a transalkylation zone by changing a destination of a stream rich in an aromatic C9 for increasing production of at least one of benzene, toluene, para-xylene, and an aromatic gasoline blend. The method can include providing the stream rich in an aromatic C9 from a first fractionation zone that receives an effluent from a second fractionation zone. The second fractionation zone may produce a stream rich in at least one of benzene and toluene. The stream rich in the aromatic C9 can be at least partially comprised in at least one of the feed to the transalkylation zone and the aromatic gasoline blend.

  • Patent number: H2244
    Abstract: A reforming process in which a hydrocarbon feed containing aliphatic hydrocarbons is converted to a hydrocarbon product comprising an increased proportion of aromatics by passage over a reforming catalyst in a sequence of moving bed reactors operating under reforming conditions including moderate hydrogen pressure. The process is applicable when a former fixed moving bed reformer has been converted to moving bed reactor operation with the recycle and other ancillary equipment retained so that moderate pressure (hydrogen partial pressure at least 11 barg) is required, usually with a catalysts such as Pt/Re which tend to exhibit excessive hydrogenolysis activity in moving bed service. The recycle hydrogen stream is split with a portion going to at least one reactor subsequent to the first reactor.
