Get alternative combustile from vegetable oils using catalytic transformation is a very interesting possibility, that begin to be research from petroleum crisis in 1973 and 1978, has an advantage from others ways of energy because it do not vanish the soil nor harmful the ambient. IME catalysis group development research in combustile renewable source since 1979, with several publications. At first, were researched several vegetable oils and were evident that oils must be pre - hydrogenated in order to improve the quantity of hydrocarbons like diesel oil. So far, when the acidity of solids catalysts were studied, Brönsted and Lewis acidity from supported catalysts with differents acidity were compared, using soinbean oil not hydrogenated, babaçu and "pinhão manso and wild", and others fatty acids as models compounds. So, carboxylic acid were studies as models compounds and the vegetable oil reforming on acids catalysts with niobium, modifying zeolites or not by rares earth, in order to get more quantity in biodiesel. This paper objective is notice the research that since 1970 decade is done by this group improving vegetable oils as renewable energy source
