The main objective of this study is to explore the feasibility of usingan abundant agricultural residue in Taiwan, rice straw, as raw material in chemi-mechanical pulping to produce pulps of adequate quality. The experimental work involved liquid-phase cooking of the straw materials, followed by refining and evaluation of pulp properties. The parameters which affected the cooking outcomes were analyzed using a factorial experimental design consisting of 3 variables at 2 levels, and the correlations between the dependent and independent variables were thus established. Liquid phase cooking using 10% total sulfur dioxide and a liquor pH of 10.5 at 150℃ for 22.5 min gave a pulp with about 66% yield and when beaten to 200mL CSF, produced handsheets of adequate strength properties.
