  • Patent number: 8795993
    Abstract: A process is described for producing fermentable sugars derivable from biomass that contains polysaccharide, such as cellulose, made increasingly accessible as a substrate for enzymatic degradation or other methods of depolymerization. These fermentable sugars are subsequently able to be fermented to produce various target chemicals, such as alcohols, aldehydes, ketones or acids.
    Type: Grant
    Filed: February 3, 2010
    Date of Patent: August 5, 2014
    Assignee: Hercules Incorporated
    Inventors: Herbert T. Conner, Patrick J. Cowan, John C. Gast

  • Publication number: 20110129880
    Abstract: In this invention, a process for producing fermentable sugars derivable from biomass that contains polysaccharide, such as cellulose, which has been made increasingly accessible as a substrate for enzymatic degradation or other methods of depolymerization. The process of the present invention increases accessibility of polysaccharides, typically present in biomass and produces polysaccharides with increased accessibility. The polysaccharides with increased accessibility may be subsequently saccharified to yield fermentable sugars. These fermentable sugars are subsequently able to be fermented to produce various target chemicals, such as alcohols, aldehydes, ketones or acids.

  • Patent number: 5176794
    Abstract: One or more layers of a sheet comprising (1) 60% to 99%, based on the weight of solids, of vermiculite delaminated by mechanical means only, (2) 1% to 40%, based on the weight of solids, of at least one fibrous material and (3) 0.1% to 4%, based on the weight of the vermiculite, of at least one flocculating agent, can be used to protect heat-sensitive substrates such as resin matrix composites from fire or heat.

  • Patent number: 5139615
    Abstract: Disclosed is a process for making a composite sheet using papermaking techniques. The composite sheet comprises (1) 20% to 99%, based on the weight of solids, of vermiculite delaminated by mechanical shearing only, (2) 1% to 80%, based on the weight of solids, of at least one fibrous material and (3) 0.1% to 10%, based on the weight of the vermiculite, of at least one flocculating agent.

  • Patent number: 5137656
    Abstract: An aqueous dispersion of vermiculite lamellae is provided having incorporated therein from about 0.2 to about 10% by weight of at least one internal sizing agent based on the dry weight of the vermiculite in the dispersion.
