Alkaline delignification of lignocellulosic biomass for the production of fermentable sugar syrups

The objective of this study to analyze the effect alkaline pretreatment on structure, composition, and subsequent hydrolysis agricultural wastes. An increase in content reducing sugars after is achieved. Its effectiveness confirmed, offering a practical procedure produce alternative energy. Factors such as calcium hydroxide concentration (0.1 0.5g Ca(OH)2/g-dry matter), liquid solid ratio (12 28ml/g-dry temperature (40 70°C), stirring rate (0 200rpm), an average particle size (0.45 1.015mm) were assessed using experimental design. On average, kikuyo grass had highest lignin removal (28.31%) while African oil palm fiber lowest value (14.10%). was statistically significant factor for fiber, important during grass.
