Production of bioethanol from agriculture waste
Ali Aboul Rahim student of Class: B.Sc Chemical Engineering Technology Department Of Chemical Engineering UET Lahore represent his research poster in all Pakistan students poster and project competition(SPPC) organized by mechanical engineering department UET Lahore KSK Campus.
Agriculture waste is a biomass material that comes from plants such as wheat straw, rice straw, switch grass, wood, rough paper, baggas etc. It contains cellulose, hemicellulose and lignin, their composition varies with type of plant species. Sugars from this biomass is released using hydrolysis methods called digestion. Digested solution contains various concentration of sugars that is fermented to produce Bioethanol. Finally, bioethanol is separated from aqueous solution using fractional distillation. Ethanol is an oxygenated compound that contains 35% oxygen, which produced no particulate and NOx emissions
during combustion. Collectively, ethanol has fewer greenhouse gas emissions. That is why bioethanol is one of the most common biofuel due to the reason its fuel properties are very similar to gasoline. It can either be used as a alternative to gasoline or in blended form. Production of bioethanol from agricultural waste is very cheaper and its commercial production can help to reduce the petroleum imports.
Cellulose is an organic compound with the formula (C6H10O5) “n” a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked
D-glucose units. where “n” is the degree of polymerization of the polymer. Typical ranges of cellulose chains in plants are anywhere from 300 to 10,000 units, varying from plant species to plant species
