Development of new methods for determination of sugars, furanic aldehydes and ironic acids from lignocellulosic materials derivatives of cane sugar

Abstract

The energy needs of modern society are based primarily on the use of fossil fuels, which besides being finite cause numerous environmental problems. Due to this situation, the search for alternative renewable energy sources has intensified exponentially in order to meet the rising demand of energy.In this scenario, the lignocellulosic materials are presented as one of the viable alternatives in relation to fossil fuels, because it is a material rich in carbon and renewed availability. Among these materials, sugar cane bagasse, a residue of sugar mills, is a promising source for generating biofuels.The process of conversion of biomass to ethanol involves several steps such as pretreatment, hydrolysis, fermentation and distillation. During these steps is very important to know the composition of the different compounds participants to assess the efficiency and optimization of the steps involved in this process.The development of new methods of determination that are fast, sensitive and selective for specific compounds is highly essential in order to perform this conversion with yields economically competitive. Among these new methods of determination, one that uses the technique of liquid chromatography (HPLC) with electrochemical detection is presented as one of the most promising, since this technique stands out for being sensitive and selective, small display limits detection and a wide applicability to different substances.Therefore, this project aims to develop new methods for the determination of sugars, uronic acids and furanic aldehydes using HPLC with electrochemical detection technique aimed at producing lignocellulosic ethanol. The development project includes the preparation and characterization of modified electrodes, as well as the methodology for determining these compounds and their application in the determination of lignocellulosic materials derived from sugar cane.
