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 1700C, resulted in extraction yield and holocellulose removal of 86% and 11 %, respectively. Also, the pulping optimum conditions were alkali charge 17%, 165 OC for I h. 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 tensi Ie index and the burst index were found to be lower when PRE-EXTRACTION was applied.
