Abstract
The mechanism and kinetics during kraft pulping of Amur silver grass w ere studied. The relationships between KMnO4 number and lignin content in pulp, effective alkali concentration and cooking temperature, effe ctive alkali concentration and KMnO4 number were derived. The activati on energy was calculated. The relative rate constants at various tempe ratures were also derived. Then, the relationships between the H - fac tor and the initial concentration of effective alkali, yield and hardn ess of pulp were derived in formulas.
