  • Publication number: 20120065449
    Abstract: Provided are hydroisomerization catalysts for processing a bio-based feedstock into biodiesel fuels. These catalysts comprise a catalytic material and a matrix component. The catalytic material is made up of a molecular sieve that has a pre-loaded platinum group metal. The catalytic material and the matrix component are processed together to form the hydroisomerization catalyst. Methods of making these hydroisomerization catalysts include synthesizing a molecular sieve; purifying the molecular sieve; associating the molecular sieve with a platinum group metal in the absence of the matrix component to form the pre-loaded molecular sieve before formation of a catalyst body; mixing the pre-loaded molecular sieve with the matrix component to form a mixture; processing the mixture to form a catalyst body; and drying and calcining the catalyst body to form the hydroisomerization catalyst. These hydroisomerization catalysts can be used to process hydrodeoxygenated plant- or animal-derived feeds to yield a biofuel.

  • Patent number: 7902117
    Abstract: The present invention provides a thermal paper composite precursor comprising (a) a substrate layer; and (b) a base layer positioned on the substrate layer, the base layer comprising a binder and at least one porosity improver wherein the thermal paper composite precursor has a thermal effusivity that is at least about 2% less than the thermal effusivity of porosity improver-less thermal paper composite precursor. The thermal paper composite precursor is useful in making thermal paper composite.

  • Patent number: 7811375
    Abstract: A heated mixture comprising dehydroxylated kaolin and a high refractive index pigment is disclosed. When the dehydroxylated kaolin is metakaolin, the heated mixture has a GE brightness greater than 86% and a Hunter yellowness index of less than about 11. When the dehydroxylated kaolin is fully calcined kaolin, the heated mixture has a GE brightness greater than 89%. The heated mixture is advantageously used in decorative paper. Also disclosed are methods of using and making the decorative paper, and decorative laminates containing the decorative paper.
