  • Publication number: 20150152074
    Abstract: Furfural is produced by contacting a feedstock solution containing C5 sugar and/or C6 sugar with a solid acid catalyst using reactive distillation. Both high yield and high conversion are obtained, without production of insoluble char in the reaction vessel. Degradation of furfural is minimized by its low residence time in contact with the solid acid catalyst. Higher catalyst lifetime can be achieved because the catalyst is continually washed with the refluxing aqueous solution and not sitting in high-boiling byproducts like humins, which are known to be deleterious to catalyst lifetime.

  • Patent number: 7491003
    Abstract: This invention pertains to a method and apparatus for thermally developing a photosensitive element. The photosensitive element includes a composition layer capable of being partially liquefied upon heating. Heating the layer causes one or more organic compounds in the layer to form a vapor. Oxidation of the vapor forms carbon dioxide and water vapor and reduces the need to manage waste streams containing the organic compounds.

  • Patent number: 5524648
    Abstract: A combined brush and comb ("brush-comb") is used to apply tones, touches or streaks of hair treatment liquid to human hair. The brush-comb has a curved body portion terminating in a tip, which may be used to part the hair, and a head portion having comb tines and brush tufts positioned close to the tines. Each tine has at least one and preferably a plurality of grooves perpendicular to its axis to retain the liquid and to replenish the liquid to the brush tufts. In operation, the brush-comb head portion is dipped into a container of the liquid and then the head portion is pulled through the hair to apply touches of the liquid to selected areas of the hair.

  • Patent number: 4791090
    Abstract: A catalyst support is made with a bidisperse micropore size distribution. One region has small micropores with an average pore diameter of less than 100 Angstrom units. The other region has large micropores with an average pore diameter which is between 100 and 600 Angstrom units. By adding catalytic metals for desulfurization and demetallation, a hydrotreating catalyst is made which is able to treat heavy feeds containing large metal bearing molecules. In a preferred embodiment the desulfurization metals are placed in the small micropores and the demetallation metals are placed in the larger micropores.
