Abstract

Green liquor has lower hydroxide concentration and higher sulfidity, which makes it a better choice for modified alkali cooking. This paper studied process parameters of pretreatment stage on pulping properties of poplar green liquor pretreatment-Kraft pulping process. Conditional experiments with green liquor charge of 0.50L/kg, 0.75L/kg, 1.00L/kg and 1.25L/kg, maximum pretreatment temperature of 95°C, 105°C, 115°C and 135°C, and holding time of 30min, 60min and 90min, were carried out. The results shows that optimal pretreatment conditions are as follows: green liquor charge, 1.00L/kg; maximum pretreatment temperature, 115°C; holding time, 60min; and wood to liquor ratio, 1:4.
