Study on Bamboo Kraft Pulping with DTPMPA

Abstract:

DTPMPA (Diethylene Triamine Penta Methylene Phosphonic Acid) was used as cooking additive in Bamboo pulping. The effect of cooking parameters such as alkali charge, maximum cooking temperature, and time at maximum temperature on bamboo kraft pulping adding additive Diethylene Triamine Penta Methylene Phosphonic Acid was studied. The results show that the optimized bamboo kraft pulping conditions are: alkali charge 17%, maximum cooking temperature 162°C, and time at maximum temperature 60min when DTPMPA dosage is 0.4%. On the optimized conditions of cooking, the highest screened bamboo pulp yield 49.52%, the kappa number of bamboo pulp is 24.68, residual alkali in kraft waste liquor 3.62g/L .
