Low Temperature Soda-Oxygen Pulping of Bagasse.
Wood shortages, environmental pollution and high energy consumption remain major obstacles hindering the development of today's pulp and paper industry. Energy-saving and environmental friendly pulping processes are still needed, especially for non-woody materials. In this study, soda-oxygen pulping of bagasse was investigated and a successful soda-oxygen pulping process for bagasse at 100 °C w...
متن کاملinvestigation on soda and soda- aq pulping of whole kenaf
the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...
متن کاملManufacturing Paper Sheets from Olive Wood by Soda, Sulphite and Kraft Pulping
Paper sheets from Iranian olive tree produced by soda, sulphite and kraft pulping.Then the influence of pulp beating on properties of paper sheets was studied. Kraft pulp exhibited the highest holocellulose/yield -cellulose/yield ratios and the sulphite pulp the soda pulp the highest lignin/yield ratio. Paper sheets from kraft with the breaking length 5851 m, stretch 4.61%, Burst index 4.48 KN/...
متن کاملinvestigation on soda oxygen delignification reaction kinetics of old corrugated container (occ) pulping
the kinetics of old corrugated container (occ) soda-oxygen delignification was investigated. three delignification temperatures (145,165 and 175ºc) were applied. the pulping duration was adjusted at 150 minutes and the measurements were conducted at 10 minutes intervals. the pulping consistency, oxygen pressure and active alkali were constant at 10%, 6 bar and 18% naoh respectively in all pulpi...
متن کاملThermomechanical Pulping of Loblolly Pine Juvenile Wood
Intensive forest management, with a heavy emphasis on ecosystem management and restoring or maintaining forest health, will result in the removal of smaller diameter materials from the forest. This increases the probability of higher juvenile wood content in the harvested materials. The purpose of this study was to compare the performance of loblolly pine juvenile and mature wood unbleached the...
