Studies on Using Sugar Beet for Bio-Ethanol for Vehicle Motors

The paper presents some researches on using sugar beet for producing bio-ethanol, considering the advantages which this raw material presents compared to other materials from which bio-ethanol can be obtained. One of the reasons of using bio-ethanol for motors as a fuel is the goal to reduce of 20 % of greenhouse gases and it is established that the emissions of CO2 are much reduced in the case of bio-ethanol than that of conventional fuels. Some of the advantages presented by bio fuels are: they are obtained from renewable staples, burnig of bio-fuels releases less CO2 than oil, which means less pollution for the environment, using bio-fuels reduces the environmental pollution, they are bio-degradable and the plantation of bio-fuels leads to developing of agriculture and has a positive social impact.Some vegetal products are used for bio-fuels: corn, sugar beet, soya, rape or even oils resulted after frying foods and animal fats.The advantage of using bio-ethanol as bio-fuel is the possibilty of obtaining it using the sub-products or agricultural and industrial junks such as: straws, paper, cobs, etc. The cellulose junks can be hydrolised to simple carbohydrates, which can be fermentated to ethanol or another compunds which can be fuels or staple for chemical industry. The converssion of the woden-cellulose biomass to ethanol is mad
