| Abstract | The study was conducted to evaluate the quality of dissolving pulp of Musa sapientum L. (banana) plant stem and its potential for biorefinery. Introduction of pre - hydrolysis prior to any alkaline pulping process he lps to reduce the content of hemicellulose and consequently produce acceptably high content of cellulose pulp. Water pre - hydrolysis was done at 150 o C for 90 min. The amount of lignin, xylan and glucan in the extracted pre - hydrolysis liquor (PHL) was 1.6, 4.9 and 1.6%, respectively. Pulping of pre - extracted chips was done following soda - AQ, alkaline sulfite and kraft process. The ratio of chip to liquor was 1:7 for both pre - hydrolysis and pulping. The kraft pulping process with 20% active alkali and 25% su lfidity at 150 o C for 90 min s howed the best result. The lowest kappa number was 26.2 with a considerable pulp yield of 32.7%. The pulp was bleached by acidic NaClO 2 and the consistency was 10% based on air - dried pulp. The lowest amount of 7% NaClO 2 was u sed for the bleaching sequence of D 0 ED 1 ED 2 . After D 0 ED 1 ED 2 bleaching, the pulp showed that α - cellulose, brightness and ash were 91.9, 77.9 and 1.6% respectively. The viscosity was 19.9 cP. Hence, t here is a possibility to use banana plant stem as a raw material for dissolving grade pulp and other bioproducts . |
