  • Method of extracting sugar from sugar juice
    Patent number: 8551250
    Abstract: The present invention relates to a method of extracting a carbohydrate from a carbohydrate juice, said method comprising the steps of: a) providing an adsorbent having unsaturated hydrocarbon groups exposed on its surface wherein said groups are capable of adsorbing a carbohydrate to the (internal) surface of the adsorbent by CH/p interaction, and optionally in addition by hydrogen bonding; b) contacting said raw carbohydrate juice with said adsorbent under conditions by which said carbohydrate is adsorbed to said adsorbent by CH/p interaction, and c) desorbing said carbohydrate from said adsorbent by increasing the temperature of the carbohydrate-adsorbent complex.
    Type: Grant

  • Process for the production and recovery of hydrocarbons
    Patent number: 8048656
    Abstract: The invention is directed to a process for the production and recovery of chemicals, in particular hydrocarbons, from a fermentation medium, wherein solvent impregnated carriers are used. Accordingly, the invention provides a process for the production of hydrocarbon from a fermentation liquid comprising: —forming said hydrocarbon from said fermentation liquid using a biocatalyst;—contacting said fermentation liquid with a solvent impregnated porous carrier, which solvent impregnated porous carrier has a density that is different from said fermentation liquid, whereby said formed hydrocarbon is sorbed by said solvent impregnated carrier; —regenerating said solvent impregnated carrier, whereby a stream of said hydrocarbon is obtained; and optionally, recycling said regenerated solvent impregnated carrier.
