A STUDY CONVERSION OF SUGARS TO BIOFUEL FROM LIGNOCELLULOSIC BIOMASS

Abstract

Lignocellulosic biomass contains more than 60% of cellulose consisting of glucose that can be converted into synthetic fuel. Production of 5-Hydroxymethylfurfural (HMF) from raw lignocellulosic biomass is combination treatment of diluted acid/base-assisted pretreatment and catalytic conversion. The condition, using HCI as catalysts and carried out with dilute sulfuric acid concentrations between 1.0 to 5.0% w/w, and residence time between 33 to 40 min at stable temperature of 140 degree celsius. High glucose conversion to HMF yield of 61.3%, respectively. There were obtained at 3.3% w/w for 35 min. The activation energy for producing HMF was 76 kJ/mol in our system. The combinational treatment demonstrate an effective transformation of glucose into HMF with a high yield.
