Hydrothermal pretreatment optimization of hemicellulose dissolution of sugar palm starch industrial waste

Abstract Lignocellulosic biomass is a renewable source containing three main components: cellulose, hemicellulose, and lignin. The components can be processed into products that have high added value. Sources of lignocellulosic includes wood, grass, industrial waste, agricultural residu. Compared to other source, wastes higher potential utilized without competition for needs assist industry in waste treatment. production sugar palm starch generate which disposed the environment disturbs surrounding community not utilized. To utilize biomass, pretreatment very important step. Hydrothermal an environmentally friendly pretreatment, using harmful chemicals process. purpose this study was determine level solubility hemicellulose hydrothermal process waste. method used liquid hot water with temperature time parameters, optimization analysis response surface methodology (RSM). result obtained effective dissolving from relationship between variables on hemiselulosa modeled Y = 7.7-3.04 X 1 – 5.67X 2 + 0.4250 1.06 3.61 . results showed optimum at 195.91°C 36.725 minutes, dissolution 81.59% desirability 0.852.
