    摘要: The present invention provides a method for decreasing the fermentation inhibition in a process for producing a target chemical from a pretreated cellulosic material, the process comprising enzymatic hydrolysis of the pretreated cellulosic material and fermentation of hydrolysed material, wherein the fermentation inhibitory properties of the material subjected to fermentation is decreased by an addition of at least one reducing agent to the pretreated material or hydrolysed material. Moreover, the present invention provides the use of dithionite for decreasing the fermentation inhibitory properties of a material being subjected to simultaneous enzymatic hydrolysis and fermentation.

    摘要: The present invention relates to the use of a comparatively cheap material for the containment of at least a strongly acidic mineral acid solution highly diluted with water, by means of which saccharides are extracted from lignocellulose material by hydrolysis at a temperature of 175-240° C. and a pressure of 6-34 bar (0.6-14 MPa) as well as a time of 1-60 minutes and is characterized in that the material comprises, in addition to iron in an amount greater than any other individual substance and usually at least 50% by weight, at least chromium in an amount of 10.5-30% by weight, nickel in an amount of 2.5-29% by weight, and molybdenum in an amount of 0-7% by weight. The invention also relates to an apparatus.

    摘要: The present disclosure generally relates to a pretreatment arrangement (100) for pretreatment of lignocellulosic biomass comprising a reactor vessel (101) extending along a longitudinal center line (102) and having an upstream inlet (103) for receiving biomass and a downstream outlet (104) for discharging biomass. The pretreatment arrangement (100) further comprising a scraping device (108) configured to scrape the interior walls (111) of the reactor vessel (101) and prevent the formation and build-up of deposits.
