  • Patent number: 7223875
    Abstract: A process for the recovery of molybdenum catalyst from the epoxidation reaction product of olefins with organic hydroperoxides. The active form of the glycol-molybdate epoxidation catalyst is removed from the process stream with an anion ion exchange resin. The ion exchange resin can be either a weak base or strong base type. The preferred embodiment of the invention produces a concentrated epoxidation catalyst in the “ammonium” form that is suitable for recycle to the catalyst preparation vessel. The ammonia form is converted into the active form by evaporating the water and ammonia from the recovered catalyst in the presence of a glycol. The preferred configuration of the ion exchange process is a “Lead-Lag” system. Two vessels will be in service while the third is in the regeneration mode recovering the epoxidation catalyst. A fourth polishing vessel can also be included as a “guard bed” to prevent leakage of the molybdate catalyst into the process stream.

  • Patent number: 7223893
    Abstract: Linear 1-butene dimers and other linear alpha-olefin dimers are manufactured in high yield and with high selectivity by coupling of alpha-olefins. The coupling is accomplished by contacting alpha olefins with an iron-based catalyst activated with an aluminum-based co-catalyst. The catalyst is structured to preclude formation of multiple dimer products, and the byproducts of the olefin coupling consist almost exclusively of methyl branched olefin dimers. The dimers have potentially diverse use in areas stretching form pharmaceuticals to plastics. Linear 1-butene dimers may be particularly useful in the production of plasticizer alcohols which may in turn be used to manufacture high quality plastics with reduced leaching.

  • Patent number: 7223895
    Abstract: An ethane or other hydrocarbon feedstock is steam cracked to produce an ethylene stream which is processed in an ethylene plant recovery section to separate an ethane recycle and a polymer grade or chemical grade ethylene product stream. A portion of the ethylene product stream may then be reacted by dimerization to produce a butene stream. These formed butenes and/or butenes recovered from other sources and another portion of the ethylene product stream are reacted by metathesis to produce a propylene stream which is deethanized and separated from heavier hydrocarbons to produce the propylene product. The butene product stream may also be deethanized and is separated from heavier hydrocarbons. The overhead from the metathesis section deethanizer may be recycled to the ethylene plant recovery section.

  • Patent number: 7223896
    Abstract: This invention provides processes for maintaining a desired particle size distribution in an oxygenate to olefin reaction system. In one embodiment, the invention comprises replacing lost catalyst fines with less active co-catalyst particles. By adding less active co-catalyst particles to the reaction system, desirable fluidization characteristics and hydrodynamics can be maintained without affecting the overall (or primary catalyst) performance and product selectivities. The invention is also directed to a population of catalyst particles having a desirable particle size distribution well-suited for realizing ideal fluidization and hydrodynamic characteristics.

  • Patent number: 7223897
    Abstract: A process for the production of an olefin from a hydrocarbon by autothermal cracking, which process comprises: partially combusting the hydrocarbon and an oxygen-containing gas in the presence of a catalyst, wherein the stoichiometric ratio of hydrocarbon to oxygen is 5 to 16 times the stoichiometric ratio of hydrocarbon to oxygen required for complete combustion of the hydrocarbon to carbon dioxide and water, characterised in that the catalyst comprises palladium and at least one further metal being a Group IIIA, Group IVA, VA, a transition metal or a lanthanide.

  • Patent number: 7223898
    Abstract: A process for the isomerization of a feedstream comprising C5–C6 hydrocarbons where the process involves charging hydrogen and a feedstream comprising at least normal C5–C6 hydrocarbons into an isomerization zone and contacting said hydrogen and feedstream with an isomerization catalyst at isomerization conditions to increase the branching of the feedstream hydrocarbons and produce an isomerization effluent stream comprising at least normal pentane, normal hexane, methylbutane, dimethylbutane, and methylpentane has been discovered. Without passing through a stabilizer, the isomerization effluent stream is passed to a deisohexanizer zone to generate at least a stream enriched in methylbutane and dimethylbutanes. The stream enriched in methylbutane and dimethylbutanes is passed to an isomerate striper column to remove butane and lighter hydrocarbons and gasses. The remainder containing the methylbutane and dimethylbutanes is collected for use in, for example, gasoline blending.

  • Patent number: 7223900
    Abstract: The present invention provides a sanitary napkin that is thin (less than 5 mm in thickness), highly absorbent and has a lateral flexibility allowing for controlled deformation when in use, namely the assumption of a “W” pattern. This controlled deformation provides a good comfort potential and simultaneously reduces the likelihood of bunching due to compression forces exerted laterally against the napkin by the thighs of the wearer. In a specific example, the sanitary napkin is characterized by a pair of preferential bending zones extending along the longitudinal axis of the sanitary napkin and by a pair of longitudinal adhesive zones on the liquid-impervious barrier layer of the sanitary napkin, that register with the preferential bending zones. The longitudinal adhesive zones fasten the sanitary napkin to the undergarment at the areas at which the sanitary napkin is intended to fold when subjected to lateral compression.
