ACID BASED HYDROLYSIS PRETREATMENT OF SUGARCANE LEAVES TO MANUFACTURE ETHANOL

The use of ethanol is increasing throughout the world for number of reasons. It is mainly used as potential alternative for fuels to fulfill the need of country for economic development. The production of ethanol in our country does not satisfy the need from industrial sector. So large amount of ethanol we have to import from foreign country. Hence to avoid this dependency we have to increase the production of ethanol in our country. Ethanol is mainly produced from sugarcane molasses and grains. As sugarcane is water intensive crop, its production is depending upon whether conditions. As a weather condition fluctuates it affects the production and cost. And we can not increase the production of sugarcane beyond certain limit. At the same time these raw materials were mainly used as food resources. Hence unintentionally it creates the diversion of food resources, prices increases which results to food v/s fuel crisis. Hence to overcome the situation this is the today’s need to develop the bio ethanol from such materials which does not used as food resources. Lignocellulosic material is found as feasible raw material for the development of bio ethanol. But its commercialization is highly limited because of its high cost processing technologies and enzymes. Hence the production of bio ethanol from lignocellulosic raw material being challenge in the future. Lignocellulosic biomass is made up of cellulose, hemicelluloses and lignin. The desired cellulose content is generally bounded by hemicelluloses and then lignin. The lignin is necessary to separate to increase the accessibility of cellulose by carrying out the pretreatments. The numbers of pretreatment methods are available but not the single method is resulted as best option because as the raw material gets change the effective pretreatment process also changes. These processes are still under research to increase the economy and efficiency. This document presents why sugarcane leaves as raw material, general procedure to carry out the pretreatment, DNSA method to find the content of reducing sugar, acid based hydrolysis processes at optimized condition.
