1. Evaluation of the Fluid Dynamic Properties and Kinetic Study by Pressurized Differential Scanning Calorimetry (PDSC) of Ethanolic Biodiesel Derived from Used Frying Oil / Avaliação das Propriedades Fluído-dinâmicas e Estudo Cinético por Calorimetria Exploratória Diferencial Pressurizada (PDSC) de Biodiesel Etílico Derivado de óleo de fritura usado
The present work aimed at investigating the biodiesel issuing from the transesterification of used frying oil with ethanol, via alkaline catalysis. Such investigation covers its thermo-oxidative stability during heating (thermal analysis and rheological properties) as well the kinetic profiles of the samples in the best oxidative induction time by the techni

2. Análise termo-oxidativa do biodiesel de girassol (helianthus annuus) / Thermo-oxidative Analysis of Sunflower (Hellianthus annus) Biodiesel
The present work aims at investing the biodiesel obtained from the transesterification of sunflower oil by means of alkaline catalysis using 30% of ethyl alcohol, 1% KOH for each 100g of oil and (1:6) oil/alcohol molar ratio. The overall content of ethyl esters (99.72%) was determined by gas chromatography coupled to mass spectrometer, confirm the efficiency

3. Verification of diesel fuel lubricity behavior with addition of ethanol. / Verificação do comportamento da lubricidade do óleo diesel veicular com adição de etanol.
A study in the lubricity behavior of blends of anhydrous ethanol in diesel fuel was carried on using the High Frequency Reciprocating Rig method, which is usually employed for predicting the wear that the fuel injection system of a diesel powered vehicle is subjected due to the degree of lubrication provided by the fuel. The addition of anhydrous ethanol to

4. Use of a biofuel obtained from the fast pyrolysis of sugarcane trash in an Otto engine / Uso de biocombustivel da pirolise rapida da palha de cana em um motor de ciclo Otto
In September 2002 the state of São Paulo promulgated the Law Nº 11241 by which was codified the gradual elimination of fire as a method to remove trash from the sugar-cane fields before harvestig. Large amounts of sugar-cane trash with an important energy potential will be available as a result of this law. New technologies to harvest and process this biom

5. Estudo Termoanalítico, Cinético e Reológico de Biodiesel Derivado do Óleo de Algodão / Thermoanalytic, kinetic and rheological study of biodiesel derived from cotton oil
Most of the world energy consumption derives from oil, coal and natural gas. The shortage of the energy sources, especially the energy from fossil fuels, and moreover the impossibility of its renewal has motivated the development of technologies that allow for the usage of renewable energy sources. Biodiesel is biodegradable, renewable and it obeys the cycle
