investigation 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 کاملSomatic Embryogenesis of Populus deltoides
Node, internode, and leaf explants of Populus deltoides Bartr. ex Marsh. × Populus deltoides Bartr. ex Marsh. hybrid poplar clone (89 M 066) tissue culture regenerated plantlets were used for direct and indirect somatic embryogenesis. Direct somatic embryos were differentiated on node, internode and leaf explants on Murashige and Skoog basal medium (MS) supplemented with N 6 -Benzyladenine (BA)...

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 of the Allometric Models in Estimation of Poplar (Populus deltoides) Height
One of the most important issues in forest biometrics is the use of allometric functions to estimate the tree height by using diameter-height models. Measuring the total height of trees is usually a complex and time-consuming process. In allometric functions, the diameter is measured directly but the height of the tree is an estimate of an allometric model, which will be more accurate if the cr...
