"Industrial development and world population are increasing uninterruptedly, which requires high energy consumption day by day. In fact, oil load crude, coal and others Natural gases are growing from time to time Responsiveness to global climate change and the uncertainty of fossil fuels have therefore led to the development of renewable energy Biofuels are the main renewable dynamism holding back. attention in this 21st century. biogas is the dominant energy and in high demand (Asmamaw and Fassil, 2014).Say no to plagiarism.

Get the original essayEthanol, which is an ancient organic solvent next to water, is named "bioethanol", due to its production by fermentation process using microorganisms. The conversion of sugars to ethanol is one of the first anaerobic organic reactions employed by humanity, keeping in mind the global demand for energy and the pathetic quality of the environment. urgent need for liquid fuel that is renewable and sustainable and can be achieved after bioethanol production (Memon et al., 2017). It is one of the oldest recreational drugs and renewable products. Antoine Lavoisier defined ethanol as a compound of carbon, hydrogen and oxygen. In 1808, Nicolas-Théodore de Saussure determined the chemical formula. In 1908, Henry Ford designed a fuel with a mixture of gasoline and alcohol and it was called the "fuel of the future" in 1925. The Arabs and Romans learned to isolate alcohol and use it industrially in the preparation. perfumes, cosmetics and medicines (Zabed et al., 2014). Two thousand years ago, even the Harappans seemed to know the reported process of alcoholic fermentation (Wang et al., 2005). This ethanol (C2H5OH) which is pure color, water-free, volatile and flammable. It has a molecular weight of 46.07, a melting point of -115 0C, a boiling point of 78 0C and a specific density of 0.79 GM/ml at 20 0C. It has a high oxygen content, which burns completely and releases fewer pollutants. It can be produced in two forms: hydrated and anhydrous (Sembiring et al., 2014). Ethanol is one of the most environmentally friendly and advanced liquid fuels. Ethanol is non-toxic and renewable from the fermentation of carbohydrate or sugar fractions of plant biomass materials (Sembiring et al., 2014). Bioethanol is a major component of alcoholic beverages such as beer, wine, whiskey, brandy, etc. used as a solvent in syrups. Food and energy security have always been a top priority, due to their limited availability and increasing demand from an ever-growing population. In recent years, a significant effort has been made to increase the production of bioethanol. Several authors have reported that attention has been paid to the conversion of various substrates such as molasses, sugarcane, sorghum, potato, cassava, cashew, apple juice, juices fruits and corn, wheat, pearl millet, rice to feed bioethanol (Asmamaw and Fassil, 2014). Bioethanol is compatible with water and with many organic solvents such as pyridine, acetic acid , glycerol, acetone, benzene, carbon tetrachloride, chloroform, diethyl ether, ethylene glycol, nitromethane and toluene. It can also be mixed with light aliphatic hydrocarbons such as pentane and hexane as well as aliphatic chlorides such as trichloroethane and tetrachloroethylene. Focus."
