  • Publication number: 20100136634
    Abstract: Method and equipment for production of fermentable saccharides, ethanol, furfural, furane, lignin, acetic acid and formic acid from lignocellulosic and amylaceous materials. The method comprises one-stage or two-stage continuous thermo-compressive hydrolysis of ligno-cellulosic particles, cellulase treatment of unreacted lignocellulose, amylase treatment of formed monosaccharides combined with added amylaceous materials, and fermentation of the combined processed monosaccharide solutions into ethanol. Side products furfural, methanol, acetic acid, formic acid and lignin are recovered and purified, optionally furfural is further converted to furan. An integrated process for recovery and recycling of all products and by-products, and recycling of heat energy is disclosed.

  • Publication number: 20070298477
    Abstract: By means of the continuous pressure hydrolysis of lignocellulose material and subsequent enzymatic hydrolysis of solid unhydrolysed residues is obtained glucose, to which starch raw materials are added and all of which undergoes amylolytic cleavage and spirituous fermentation. Ethanol, furfural, acetic and ligin are obtained. The device, which comprises the filling unit, hydrolysers, expanders, distilling and rectifying columns is represented in that the continuous worm pressure filling unit (13) consists of segments formed by the body (94) with single-threated conveyer worms (86) place on the shaft (85). Between the worms there is at least one steam ring (88), which conically widens on the input side of the raw material. In the outlet filler (93) with the reducing part leading into the first hydrolyser (22) a pressure identical to that of the first hydrolyser (22) is achieved.
