Claims (1)

Способ получения глюкозного сиропа и гидролизного лигнина из целлюлозосодержащего сырья, отличающийся тем, что грубо измельчают целлюлозосодержащее сырье до размера частиц не более 0,4 мм, измельченную массу гомогенизируют путем перемешивания и нагрева с добавлением воды, затем ферментируют при помощи нагрева и перемешивания полученной массы с добавлением в нее фермента, продуцируемого на основе грибов рода Trichoderma, ферментированную массу ингибируют дополнительным нагревом, грубо фильтруют путем охлаждения и отстаивания с осаждением нерастворимого осадка гидролизного лигнина, полученную жидкость тонко фильтруют при помощи мембраны, разделяя ее на глюкозный сироп и сорбент на основе гидролизного лигнина.A method for producing glucose syrup and hydrolysis lignin from cellulose-containing raw materials, characterized in that the cellulose-containing raw materials are roughly crushed to a particle size of not more than 0.4 mm, the crushed mass is homogenized by stirring and heating with the addition of water, then fermented by heating and stirring the resulting mass with by adding an enzyme produced on the basis of fungi of the genus Trichoderma to it, the fermented mass is inhibited by additional heating, coarsely filtered by cooling and settling with the precipitation of an insoluble precipitate of hydrolytic lignin, the resulting liquid is finely filtered using a membrane, separating it into glucose syrup and a sorbent based on hydrolytic lignin .
