  • Anhydrous ammonia treatment for improved milling of biomass
    Patent number: 8651403
    Abstract: Mechanical milling of biomass as a pretreatment to render the biomass readily saccharifiable requires high energy input. Preceding mechanical milling by treatment with anhydrous ammonia was found to greatly reduce the energy requirement for fine milling, providing a more economical pretreatment process for commercial use.
    Type: Grant
    Filed: July 19, 2011
    Date of Patent: February 18, 2014
    Assignee: E I du Pont de Nemours and Company
    Inventors: Carl E. Camp, Jelena Cirakovic, Bruce A. Diner, Janine Fan

  • BIOMASS PRETREATMENT PROCESS FOR A PACKED BED REACTOR
    Publication number: 20120125551
    Abstract: Biomass pretreatment using anhydrous ammonia was found to be effective in a static vessel when the ammonia can penetrate through the biomass particles or pieces in vapor state. To achieve this condition, total system moisture content is kept below 40 weight % based on total mass in the system. The pretreated biomass product is effectively saccharified to produce fermentable sugars for biocatalyst production of a product.

  • AMMONIA PRETREATMENT OF BIOMASS FOR IMPROVED INHIBITOR PROFILE
    Publication number: 20110250646
    Abstract: Methods for treating biomass for release of fermentable sugars with an improved inhibitor profile are provided. Specifically, a hydrolysate comprising fermentable sugars with an improved inhibitor profile is obtained by saccharification of a reaction product obtained by pretreating biomass with ammonia under suitable reaction conditions. The pretreated biomass reaction product has an acetamide to acetate molar ratio greater than about 1 and an acetyl conversion of greater than 60%. The acetamide to acetate molar ratio is maintained greater than about 1 throughout saccharification. The hydrolysate may be fermented to a target compound.

  • Adsorbent biocatalyst porous beads
    Patent number: 5486292
    Abstract: Highly porous, adsorbent biocatalyst beads of synthetic organic polymer have powdered activated carbon dispersed throughout the polymer and a biocatalyst, such as bacteria, located within macropores of the beads. The beads are used for remediation of contaminated aqueous streams. The biocatalyst can consume adsorbed organic contaminants and convert them into harmless gases, while continuously renewing the adsorptive capacity of the activated carbon.
