  • Patent number: 7786252
    Abstract: Disclosed is a process for the preparation of multilayered, shaped articles having high transparency and low haze having at least one layer contains one or more thermoplastic polymers selected from polyesters, polycarbonates, and homogeneous blends thereof, and a separate layer which contains a transamidized, homogeneous blend of a least two polyamides. The thermoplastic polymer components and the polyamide components have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enable the incorporation of regrind into one or more of the layers of the article while maintaining high clarity. These articles can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into one or more layers to impart oxygen-scavenging properties.

  • Patent number: 7736403
    Abstract: Disclosed is a process for humidifying syngas to achieve a water to carbon monoxide molar ratio in the product syngas within a desired range and in which the molar ratio which can be varied over time in response to changes in downstream syngas requirements. The raw syngas is produced by reacting a carbonaceous material with oxygen, water, or carbon dioxide and can be combined with a diluent to produce a diluted syngas stream which can be cooled and contacted with liquid water to give a humidified syngas. The H2O:CO molar ratio of the humidified syngas may be adjusted in response to time-varying downstream syngas requirements by changing the amount and/or temperature of the diluent that is combined with the raw syngas stream, by adjusting quench and heat exchange conditions, or a combination thereof. The application of the process to the coproduction of chemicals and power are also disclosed.

  • Patent number: 7674937
    Abstract: This invention is directed to a class of compounds that can be both monodentate and bidentate in their association with a transition metal to form a catalyst for reactions such as the hydroformylation of olefins to produce aldehydes. The compounds contain two phosphorus atoms having different steric and/or electronic nature. In hydroformylation catalysts, the compounds advantageously can produce a variable n/iso product mixture of aldehyde products that can be varied by simply changing process variables such as [H2]/[CO] partial pressure gas ratio or temperature/inert gas partial pressure.

  • Patent number: 7538060
    Abstract: Disclosed are catalysts comprising copper chromite, palladium and lanthanum having hydrogenation activity. The combination of copper chromite with palladium and lanthanum enhances catalyst activity more than the presence of either palladium alone or palladium in combination with alkali or alkaline earth metals. The catalysts are useful for the preparation of methanol from carbon monoxide and hydrogen and for the hydrogenation of carbonyl compounds such as, for example, aldehydes, ketones, and esters, to their corresponding alcohols. The catalysts may be used for the preparation of cyclohexanedimethanols from dialkyl cyclohexanedicarboxylates or of ethylene glycol from alkyl glycolates.
