During the pulping of different positions of betel palm stem, higher the chemical change, which would result in lower pulp yield. The chemical dosage of the soda pulping (AP) is 18%, which would result in lower pulp yield is 34.42%. Among the different positions of the betel palm stem, the middle position has the best screened yield; and the top position has the lowest screened yield. Anthraquinone (AQ) can effectively improve the delignification effect of NaOH. Results reveal the higher the addition of AQ, the lower the screened yield, and the higher the screened yield, the lower the K number (No.). The concentration of alkaline solution was 22% and liquid ratio was 6:1 in the Soda pulp pulping, results showed the paper has the best folding strength and tensile index. Tear strength has no significant difference under any condition in pulping process. Overall, the pulp yield of chemical pulping from betel palm stem was low (only 34.43% of AP) in this study, which is not suitable as a paper-making raw materials, so it should be considered for other purposes.
