The Production of Ethanol from Agola Grass and Subsidies for its industrialization

Abstract

The joint production of ethanol and sugar decreases the production of sugar, which is a necessary commodity for food. In this sense, the study tests the potential of an alternative raw material for ethanol production, namely Angola grass dried, scientifically known as Brachiaria purpurascens "Forsk" Stapf, using tests and chemical techniques of separation, acid hydrolysis and quality analysis. The production consisted in the removal of roots from samples of Angola grass, a broth was generated, acid hydrolysis was performed, and then fermentation was carried out using comparatively two types of ferments (chemical and biological), successive distillations and laboratory analyses, the results of which were satisfactory. The distillate obtained is the common ethanol alcohol content of about 94.6% V/V. Based on the production of ethanol by the conventional way, comparatively demonstrates subsidies technical, socio-economic and environmental, the industrialization advantages of ethanol production via processing Angola grass.
