Bagasse (/ bəˈɡæs / bə-GAS) is the dry pulpy fibrous material that remains after crushing sugarcane or sorghum stalks to extract their juice. [ 1 ] It is used as a biofuel for the production of heat, energy, and electricity, and in the manufacture of pulp and building materials. Agave bagasse is similar, but is the material remnants after ...
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Contents. Lignocellulosic biomass. Bagasse, the lignin-rich component of sugarcane, is a form of lignocellulosic biomass. Its combustion helps to power the sugar mill. In this photograph, the bagasse is under the blue plastic. Location: Proserpine, Queensland. Lignocellulose refers to plant dry matter (biomass), so called lignocellulosic biomass.
Through bioconversion of biomass to a mixed alcohol fuel, more energy from the biomass will end up as liquid fuels than in converting biomass to ethanol by yeast fermentation. The process involves a biological/chemical method for converting any biodegradable material (e.g., urban wastes, such as municipal solid waste, biodegradable waste, and ...
Heat is sometimes generated with unsustainable natural gas fossil fuel, but cellulosic biomass such as bagasse is the most common fuel in Brazil, while pellets, wood chips and also waste heat are more common in Europe. Corn-to-ethanol and other food stocks has led to the development of cellulosic ethanol. [25]
Ethanol is a neutral molecule and the pH of a solution of ethanol in water is nearly 7.00. Ethanol can be quantitatively converted to its conjugate base, the ethoxide ion (CH 3 CH 2 O −), by reaction with an alkali metal such as sodium: [79] 2 CH 3 CH 2 OH + 2 Na → 2 CH 3 CH 2 ONa + H 2. or a very strong base such as sodium hydride: CH 3 CH ...
The energy content of biofuel is the chemical energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density. A biofuel is a fuel produced from recently living organisms. Biofuels include bioethanol, an alcohol made by fermentation —often used as a gasoline ...
Ethanol fuel in Brazil. Appearance. hide. Six typical Brazilian flex-fuel models from several car makers, popularly called "flex" cars, that run on any blend of hydrous ethanol (E100) and gasoline (E20 to E25) Brazil is the world's second largest producer of ethanol fuel. Brazil and the United States have led the industrial production of ...
