Abstract
Sugarcane molasses are being produced in sugar industry by processing of sugarcane during the production of sugar. The demand for molasses is increasing day by day for the production of bioethanol, therefore cost of sugarcane molasses is also increasing. Bioethanol is produced from molasses by fermentation in the presence of Saccharomyces cerevisiae and Zymomonasmobils.Bioethanol acts as precursor of other chemicals.Different factors i.ethe effect of temperature, effect of pH, effect of impurities and effect of nutrients during fermentation were studied.The main countries which are producing bioethanol are Brazil and United state of America.The present workis targeted on the ethylene production from bioethanol.Three different methods were adopted for the production ofethylene frombioethanol. Method-I consist of bioethanol as raw material and alumina as a catalyst for the production of ethylene.Method-II consists of bioethanol as raw material and concentrated sulfuric acid as dehydrating agent and clean sand as catalyst. Method-III consists of bioethanol as raw materialand concentrated phosphoric acid as dehydratingagent.Method-IIproduced fruitful results for the production of ethylene but other methods did not produce satisfactory results. The main focus remained in the present work was analysis of ethylene who proved its confirmation and green nature.Ethylene was analyzed by gas chromatography mass spectrometry.
