Feasibility of Bioethanol Production From Lignocellulosic Biomass

Feasibility of Bioethanol Production From Lignocellulosic Biomass The objective of the paper is to discuss the potential of cellulosic ethanol production processes and compare them, to find the most appropriate production method for Latvia's situation, to perform theoretical calculations and to determine the potential ethanol price. In addition, price forecasts for future cellulosic and grain ethanol are compared. A feasibility estimate to determine the price of cellulosic ethanol in Latvia, if production were started in 2010, was made. The grain and cellulosic ethanol price comparison (future forecast) was made through to the year 2018.

Thermochemical Processes

The benefits and impacts of enhanced cellulosic ethanol (CE) production, the major features of existing production processes, and some current research challenges of major pretreatment processes are presented. The prospects of enhanced CE production, especially in developing economies like Nigeria are highlighted. We conclude that in order to reap the promising prospects and conquer the challenges and negative impacts of enhanced CE production, current researches for production of cellulosic ethanol must be focused on the development of processes that are capable of liberating and fermenting lignocellulose into bioethanol at faster rates, higher yields, and overall technical and economic efficiency. These researches should concentrate on the development of cheaper enzymes, genetically engineered microorganisms, and cost-effective thermochemical processes in order to accomplish the much-needed breakthrough in cellulosic biofuel production. Properly targeted innovative researches on cellulosic ethanol production processes are the sure route to effective reduction of global dependence on nonrenewable fossil fuels. The needed research breakthroughs will obviously be based on innovative integration of processes rather than on the improvement of the well-known individual processes of bioethanol production. http://dx.doi.org/10.4314/njt.v36i1.32

Hydrolysis Process

Cellulosic ethanol production has drawn much attention in recent years. However, there remain significant technical challenges before such production can be considered as economically feasible at an industrial scale. Among them, the efficient conversion of carbohydrates in lignocellulosic biomass into fermentable sugars is one of the most challenging technical difficulties in cellulosic ethanol production. Use of ionic liquids has opened new avenues to solve this problem by two different pathways. One is pretreatment of lignocellulosic biomass using ionic liquids to increase its enzymatic hydrolysis efficiency. The other is to transform the hydrolysis process of lignocellulosic biomass from a heterogeneous reaction system to a homogeneous one by dissolving it into ionic liquids, thus improving its hydrolysis efficiency.
