  • Bitumen composition
    Patent number: 11453779
    Abstract: The invention is directed to a bitumen composition, to a paving, to a roofing, to a method for preparing a bitumen composition, to a method for increasing the stiffness of a bitumen composition, to a method of adjusting the physical properties of a bitumen composition, and to the use of a bitumen composition. The bitumen composition of the invention comprises a lignin compound or derivative thereof, wherein 10 wt. % or more by weight of said lignin compound or derivative thereof is molecularly dissolved in said bitumen composition.
    Type: Grant

  • Acylation of carbohydrates
    Patent number: 8796445
    Abstract: Esterification of a carbohydrate using an acylating agent can effectively be performed using a process comprising: (a) combining the carbohydrate with the acylating agent, (b) adjusting the moisture content of the combination below 40 wt. %, and (c) subjecting the combination to superheated steam. The carbohydrate is especially starch and the acylating agent is in particular an acid, such as an organic acid, amino acid, or diacid.

  • Extraction of polysaccharides from vegetable and microbial material
    Publication number: 20040260082
    Abstract: Useful polysaccharides, such as &bgr;-1,3-glucans, from a biological raw material can be solubilised and/or isolated by treating the raw material with an oxidising agent that leads to oxidation of primary hydroxyl groups in the glucan. The oxidising agent is preferably a catalytic amount of a nitroxyl compound in the presence of a re-oxidising agent such as hypochlorite or an oxidative enzyme with oxygen or hydrogen peroxide. The polysaccharide retains its useful properties during this treatment and is, moreover, more readily available. If desired, protein material from the raw material can also be utilised.
