摘要： Methods and systems for preparing agricultural residue or other agricultural feedstock for use as a pulp. The method includes providing non-wood agricultural residue (e.g., corn stover) or other agricultural feedstock that includes agricultural fibers, chemically pulping the agricultural fibers in a preliminary alkaline chemical pulping process at a low consistency and at a low temperature to produce partially pulped agricultural fibers, such step including separating lignin and hemicellulose from the partially pulped agricultural fibers, introducing the partially pulped agricultural fibers into a first reactor, wherein the first reactor operates at a low temperature of less than 100°C (e.g., 65°C), introducing the agricultural fibers from the first reactor into a second reactor, where the second reactor operates at a low temperature, of less than 100°C (e.g., 94-96°C), the second reactor operating at a higher temperature than the first reactor, to produce pulped agricultural fibers.

摘要： A method of delignifying a fibre suspension which is obtained from alkaline pulping of a vegetable-based fibre raw material. In the present method, a fibre suspension, which comprises fibres that are suspended in the liquid phase, is treated. These fibres are first washed in order to reduce the percentage of the dissolved material generated by the cooking, using the counter-current principle, and by using, as a displacing washing solution, the filtrate liquids of stages which come later in the course of propagation of the fibres, after which the suspension of the washed fibres is fed to the delignification, where lignin is separated from the fibres by using an oxidising chemical. According to the present invention, the displacing washing solution is treated with an oxidising chemical. In this case, the oxygen which is dosed into the oxygen delignification can be used more efficiently to reduce, the kappa, number, in which case the condensation reactions of the lignin are prevented, and an oxygen delignification process is achieved which results in a lower kappa number level compared to the prior art.
