摘要

Lignocellulosic biorefinery is a promising alternative for petroleum refinery that has potential to meet a sustainable variety of needs in the future. One product of lignocelullosic biorefinery is levulinic acid (LA) which is a precursor for the production of many chemicals. Cellulose from lignocellulosic biomass is hydrolyzed to glucose, then hydroxymethylfurfural (HMF), and subsequently to LA. In this paper, the starting material was glucose, as a part of large LA synthesis project from biomass in the form of sugarcane bagasse. Glucose was reacted using 0.5 - 1.5 M hydrochloric acid catalyst at temperatures of 160 - 180°C. From the experiments, it was found that the higher the temperature and concentration of the catalyst, the higher the LA yield. However, a combination of excessively high temperature and catalyst concentration will reduce the LA yield.
