Abstract

Biomass pretreatment plays a crucial role in a lignocelluloses feedstock-based biorefinery for
processing of three major output streams (cellulose, hemicelluloses and lignin) into chemicals
and biofuels. Biomass pretreatment includes processing of lignocellulosic material under
aqueous, dilute acid or alkaline media to obtain a cellulosic fraction, which in then produce
added-value products. In this study, the effect of pre-extraction on alkaline pulping (soda)
and papermaking properties of Bagasse was investigated. Samples of sugar cane bagasse
were hydrolysed by auto hydrolysis with hot-water. Results showed that pre-extraction
optimum conditions were 30 min, 135OC and 10 min 170OC, resulted in extraction yield and
holocellulose removal of 86% and 11%, respectively. Also, the pulping optimum conditions
were alkali charge 17%, 165 OC for 1h. The results indicated that for unbleachable pulp
production the pulping yield from the extracted bagasse is higher than the unextracted bagasse
but the bleached pulp from unextracted bagasse have higher yield compared to the extracted
bagasse. Pulp strength properties such as the tensile index and the burst index were found to be
lower when pre-extraction was applied.
