  • Method of converting cellulosic biomass to alcohol using web comprising fine fiber and bioactive particulate
    Patent number: 8334121
    Abstract: The assemblies of the invention can comprise a fine fiber layer forming a multilamellar web or matrix, having dispersed within the fine fiber layer a bioactive particulate material, including cells, enzymes or microorganisms. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the bioactive particulate within the nanofiber layer. The assemblies of the invention can be used to treat or purify fluid streams. The assemblies of the invention can be used in conjunction with a bioreactor system, a bioartificial organ, or a culture container.
    Type: Grant
    Filed: February 13, 2007
    Date of Patent: December 18, 2012
    Assignee: Donaldson Company, Inc.
    Inventors: Melvin S. Schindler, Veli Engin Kalayci, Mark A. Gogins
  • WEB COMPRISING FINE FIBER AND REACTIVE, ADSORPTIVE OR ABSORPTIVE PARTICULATE
    Publication number: 20120272828
    Abstract: The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.
