| Abstract: | The objective of this study is to optimize the process of low solids cooking of eucalyptus wood by laboratory simulation.All cook parameters were based on the factory actual production and were in duplicate to obtain pulp of 16～18 kappa number and residual alkali was control in range of 6～8 g.L-1.The results showed that the optimum conditions of low solids cooking were as follows:Wood chips steaming time 30 min,the alkali ratio of the two stage 55:45,the active alkali charge 21%(based on NaOH),the extraction temperature 135℃,H factor 1200～1300. |
