Biomass Energy: Bio-Ethanol Production From Date Molasses Using Alcoholic Fermentation

摘要

The production of bioethanol from date molasses is one of the effective discoveries in the field of Sustainable development represented in positive exploiting of renewable energies mainly biomass energy. The paucity of ethanol gas at the Sirte University was the stimulator for considering this research. The study was conducted in the chemistry labs at the Sirte University in 2018 to investigate the possibility of producing bioethanol from date molasses determining the effect of different temperature, PH, yeast quantity and fermentation time in molasses on the amount of ethanol produced. Three samples of molasses were taken in different sizes. Bioethanol was indirectly extracted through alcoholic fermentation of date molasses in anaerobic conditions. Because of the lack of a low-pressure distillation device, a normal distillation device was used. The best amount of bioethanol (25ml) was extracted at the largest quantity of yeast (2g), the longest fermentation time (236h), the highest fermentation's temperature and PH 4.8. Ethanol specifications were examined via qualitative tests.
