biodiesel

well with each other. Environmentally, the use of biodiesel is limited by the increase of aldehydes, nitrogen oxides and acrolein emissions. The present study had as goal the survey of the UCO´s situation and the evaluation of its potential in producing biodiesel. Such fact demands the study of the whole problem in using UCO´s to produce biodiesel. In this sense, one has made a systematization, analysis and debate of the extensive and diversified information that is available on the referred subject, including the technologies for biodiesel production from used vegetable oils, available in the market. In the following phase was planning a preliminary study of transformation of UCO´s for biodiesel obtaining, for that I began to work with oleic acid. I intended to test the enzymatic transformation in the methyl ester corresponding and to evaluate the yield of this transformation in function of several experimental parameters. The following phase would consist of applying the same conditions for UCO´s, however the time didn't make possible to move forward for that study. It is the suggestion for a future work. Finally, was made a identification of the potential of biodiesel use and the impacts that can occur, mainly at the level of the environment. For this experimental work, two parameters were changed, the total volume (oleic acid and methanol) and the stirring speed (rotation). The enzyme proportion:alcohol:methanol was kept constant, by using 3%…
