Bio‐Alcohol

Fossil fuels make up 60% of the total fuel consumption worldwide in the transportation sector and are increasing day by day. It emits carbon dioxide and carbon monoxide and its increasing level in the environment has been a major concern for its protection. The use of natural gas instead of fossil fuels is an important strategy to reduce environmental impact. Biomass chemical reactions include bioalcohol biofuels, carbohydrates, and lignin. Bioethanol and biobutanol are commonly used in bioalcohol fuel. Some bio-alcohols, on the other hand, can be processed by biochemical processes. The composition, purification, and distribution of bio-methanol, biopropanol, bioglycerol, bioethylene glycol, and branched-chain bioalcohols are included in this chapter. The purification methods used for bioalcohols (Distillation, Adsorption, Ozonation, Gas striping, Pervaporation, Vacuum fermentation, and Solvent extraction) are described. Gas Chromatography, highly efficient Liquid Chromatography, Infrared Spectroscopy, and Olfactometry Techniques have been widely defined for the classification, identification, and volume of biological alcohol.
