properties of bleached alkaline sulfite anthraquinone pulp from old corrugated container
the properties of alkaline sulfite anthraquinone (as/aq) pulp from old corrugated container (occ)was studied. in each trial 100 grams (based on dry weigth) of occ and 18% active alkali was used.three levels of anthraquinone (0.0.1 and 0.2% based on dry weigth of the occ) and two pulpingtimes (120 and 150 minutes at maximum pulping temperature) were applied. pulping temperature,na2so3/naoh ratio...
متن کاملBioproducts from sulfite pulping : Bioconversion of sugar streams from pulp , sludge , and spent sulfite liquor
The production of singleand mixed-sugar streams and their conversion to bioproducts were studied using sulfite pulping streams as feedstocks. Sulfite pulp, sludge, and spent sulfite liquor (SSL) were utilized because they are concurrently generated alongside of bleached pulp, and because the pulping process renders pretreatment unnecessary. SSL, comprised of mostly monomeric hexose and pentose ...
متن کاملCharacterization of anaerobic sulfite reduction by Salmonella typhimurium and purification of the anaerobically induced sulfite reductase.
Mutants of Salmonella typhimurium that lack the biosynthetic sulfite reductase (cysI and cysJ mutants) retain the ability to reduce sulfite for growth under anaerobic conditions (E. L. Barrett and G. W. Chang, J. Gen. Microbiol., 115:513-516, 1979). Here we report studies of sulfite reduction by a cysI mutant of S. typhimurium and purification of the associated anaerobic sulfite reductase. Sulf...
متن کاملPurification of Alkaline Phosphatase
8. An increase in the rate of progression of the bands down the column decreases the sharpness of the bands. On 'Zeo-Karb 215' (40-60 mesh/in.) a rate ofprogression of 10-15 cm./hr. gave satisfactory results. 9. Equations have been derived permitting the calculation ofthe proportion ofthe column occupied by a component, the width ofthe boundaries and the expected yield of pure components in sep...
متن کاملAlkaline Sulfite Anthraquinone and Methanol Pulping of Bamboo (Gigantochloa scortechinii)
Alkali ratios and cooking time of the alkaline sulfite anthraquinone (AQ) and methanol (ASAM) pulping process of bamboo (Gigantochloa scortechinii) were studied. Bamboo chips were cooked at three different levels of sodium hydroxide and cooking time, namely 14, 16, or 18% for 60, 90, or 120 minutes. Pulping parameters that remained constant were the use of 0.5% ethylene diamine tetraacetic acid...
