Diversification in fuel production is an extremely important factor, as the sources of fossil origin, which are the most used, will exhaust themselves from nature, in addition to being extremely polluters. Therefore, the development of biofuels has become a great option in the search for the development of new fuel alternatives.
One of the ways to obtain biofuel is through the processing of biomass, which is composed of firewood, bagasse and sugarcane, forest residues, agricultural residues, corn straw, rice husks, among other materials organic. Cellulosic ethanol, for example, is a biofuel produced from biomass.
This fuel differs from “common” ethanol in terms of its raw material and the way it is processed. Cellulosic ethanol is manufactured through chemical reactions that break the chains of the main polymers that form the structure of plants: cellulose, hemicellulose and pectin. This process takes place through enzymatic hydrolysis or fermentation and distillation.
One of the positive aspects of cellulosic ethanol production is that its raw material is a by-product of its activities. agricultural, not useful for human nutrition and having few nutrients to be destined for cattle. Therefore, the use of these residues for the manufacture of fuel is an extremely useful way for the final disposal of biomass.
This biofuel can be added to gasoline, as well as being used pure. However, the vehicle must be adapted to receive cellulosic alcohol. Experts say that this fuel is an excellent option in the search for alternatives that are less harmful to the environment and human health. Its use emits less polluting gases into the atmosphere, a fact that contributes to minimizing the greenhouse effect.
