  • Switchable ionic liquids for biomass pretreatment and enzymatic hydrolysis
    Patent number: 11118204
    Abstract: In one aspect, the present invention provides a method for preparing a sugar composition. The method includes: forming a mixture including polysaccharide biomass and an ionic liquid solution, wherein the ionic liquid solution contains water and an ionic liquid, and wherein the ionic liquid contains a dicarboxylic acid anion and a cation. The pH of the mixture is greater than or equal to about 10, and the molar ratio of the dicarboxylic acid anion to the cation is at least about 1:2. The method further includes: maintaining the mixture under conditions sufficient to dissolve at least a portion of the polysaccharide present in the polysaccharide biomass; reducing the pH of the mixture containing the dissolved polysaccharide to at least about 7; adding at least one glycoside hydrolase to the mixture having the reduced pH.

  • Industrial luminaire with prismatic refractor
    Patent number: 6910785
    Abstract: An industrial luminaire with a prismatic refractor including an interior surface formed as an open-ended surface of revolution of a plane curve about a rotational axis, the plane curve having a plurality of segments corresponding to segments on a reference curve which, for each segment of the reference curve, the corresponding segment on the plane curve has been incrementally rotated with respect to a reference point on a reference axis for the reference curve.
