摘要： Kraft pulp of increased strength and bleachability may be produced with decreased consumption of effective alkali, and at a lower H factor, by keeping the dissolved organic material (DOM) concentration low substantially through the entire kraft cook, including by extracting high DOM liquid from at least one part of a continuous digester and replacing it with much lower level DOM liquid. Existing pulp mills having two-vessel hydraulic, one-vessel hydraulic, or other systems may be retrofit to provide for extractions and additions of low DOM dilution liquor (including substantially DOM-free white liquor). Also, commercial size batch digesters (8 tons perday of pulp or more) can be operated with low DOM liquor to produce increased strength pulp. Using dilution with low DOM liquor also results in reduced H factor and effective alkali consumption, and increased bleachability.
摘要翻译：通过将溶解的有机物质（DOM）浓度基本上保持在整个硫酸盐蒸煮中，包括通过从中提取高DOM液体，可以降低有效碱的消耗，并在较低的H因子下生产具有增加的强度和漂白性的牛皮纸浆连续消化器的至少一部分，并用更低级别的DOM液体代替。可以改造具有双容器液压，单容器液压或其它系统的现有纸浆厂，以提供低DOM稀释液（包括基本上不含DOM的白液）的提取和添加。此外，商业尺寸的批量蒸煮器（每天8吨纸浆或更多）可以用低DOM液体操作以产生增强的纸浆。使用低DOM溶液进行稀释也可以降低H因子和有效的碱消耗，增加漂白性。

摘要： A process for producing pulp substantially without the necessity for adding a nutrient or a cellulose degradation inhibitor, which comprises treating the raw material in the pulping step with a microorganism which grows well in a medium containing lignin as a sole carbon source. Since the addition of a nutrient or a cellulose degradation inhibitor is indispensable in the conventional microbial treatment, the present invention which can dispense with the addition of these substances can achieve a remarkable cost reduction as well as an energy saving by virtue of the microbial treatment.
