Pulp and Paper Production from Bitter Orange (Citrus aurantium L.) Woods with Soda-AQ Method

The objective of this study was to determine properties of pulp and paper produced from Citrus aurantium widely available in The Mediterranean region by applying Soda- Anthraquinon (AQ) method. Chemical compositions of C. aurantium in addition to basic properties of papers were evaluated. The results showed that C. aurantium had higher holocellulose and cellulose content values of 81.1% and 45.99%, respectively. According to results, it taught that this raw material was suitable for pulp and paper production. Then, pulps ware produced with Soda-Anthraquinon (AQ) method. Physical and optical properties of pulps were determined and effects of AQ were also investigated. Therefore, 4 different cooking experiments which added AQ in certain proportions were performed to C. aurantium woods. The best result in pulp yield was found as 42.14% in 4th cooking experiment added 0.5% AQ. Physical properties of pulps were improved by increasing AQ addition. However, optical properties were decreased. As a result C. aurantium woods can be used for pulp and paper production as a raw material.Keywords: Pulp, Paper, Anthraquinon, Citrus aurantium
