  • POLYIMIDE RESINS FOR HIGH TEMPERATURE APPLICATIONS
    Publication number: 20130171395
    Abstract: Polyimide resin compositions that contain an aromatic polyimide, graphite, and acid-washed kaolinite are found to exhibit high thermal oxidative stability. Such compositions are especially useful in molded articles that are exposed to high temperatures, such as bushings, bearings, and seal rings that are used in aerospace, transportation, and materials handling applications.

  • 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.
