Abstract:Pulping properties particularly the kraft pulping conditions of solid residue of sweet sorghum stalk after producing ethanol were researched in this paper. The results showed that the sweet sorghum stalk residue was very suitable for kraft pulping and kraft-AQ pulping. The screened yields were 51.9% and 53.5% respectively under the suitable conditions, and the various strength indexes of the pulp including tensile strength, tear strength, bursting strength, folding endurance reached a higher level.
