    • The present invention discloses the continuous process for production of cellulose pulp from grass-like plant feedstock suitable for paper making. Process comprising the steps of: preparing the grass-like plant feedstock by comminuting, dedusting, continuous digestion, disperging, diluting the cellulose pulp, screening and fractionation, concentration to remove black liquor, dilution with fresh water, yielding final cellulose pulp suitable for manufacturing of paper or cellulose sheets, and, optionally, pulp bleaching processes. The continuous digestion is performed in the vertical column at 70-100 °C for 40 minutes to 2 hours; average composition of thus formed digestion suspension is maintained within the following ranges: 0.9-1.5% w/w of NaOH; 0.15-0.4% w/w of NaCl or Na 2 SO 3 ; and 15-18% w/w of grass-like plant feedstock; where concentrations of ingredients being calculated on the weight of the liquid phase. Screening and fractionation are resulting with two fractions; one being further processed by milling, and another being further processed to final pulp with or without bleaching processes. The preferred grass-like feedstock for the process is miscanthus /Miscanthus x giganteus, Andersson/.
    • 本发明公开了适用于造纸的草类植物原料生产纤维素纸浆的连续方法。 方法包括以下步骤:通过粉碎,除尘,连续消化,分散,稀释纤维素浆,筛选和分级,浓缩以除去黑液,用淡水稀释,得到适合于制造的最终纤维素浆,制备草类植物原料 的纸或纤维素片,以及任选的纸浆漂白方法。 连续消化在立柱中在70-100℃进行40分钟至2小时; 由此形成的消化悬浮液的平均组成保持在以下范围内:NaOH的0.9-1.5%w / w; 0.15-0.4%w / w的NaCl或Na2SO3; 和15-18%w / w草样植物原料; 其中成分的浓度根据液相的重量计算。 筛选和分馏得到两个馏分; 一个通过研磨进一步加工,另一个被进一步处理成具有或不具有漂白工艺的最终纸浆。 用于该方法的优选草样原料是芒草(Miscanthus)/芒草(Miscanthus x giganteus),Andersson /。
