Reasons of using Cellulose
Why Cellulose?
There are Abundant resources in Earth.
- Don’t have to worry about running out the energy.
We don’t need to waste food.
- Solve the ethic problems for using other biomass.
We can reduce GHG(Green House Gas).
- Eco friendly energy.
What's the problems?
It is difficult to separate the cellulose from wood.
- Components of wood :
Let's see the process flow of cellulosic ethanol which we are interested in(Figure 1). At the upstream, biomass harvest undergoes a pretreatment and cellulose hydrolysis by enzymes and then fermented to ethanol through the points. The initial contract for each course are as follows.

Ethanol is nowadays an important product in the fuel market. Its market grew from less than a billion liters in 1975 to more than 39billion liters in 2006 and is expected to reach 100 billion liters in 2015. Less than 4% of the ethanol is produced synthetically from oil, while the rest is produ
3. Introduction
What is the Bio-fuel ?
- Bio-fuel is derived from biological materials which are commonly plant materials used. The purpose is to make a “sustainable transportation fuel” from biomass.
What is Bio-ethanol ?
- Bio-ethanol has been produced from biological source.
- It is produced in fermentation of sugars in the brewing industry. In this process glucose is
