1. THE BRAZILIAN EXPERIENCE WITH ETHANOL FUEL: ASPECTS OF PRODUCTION, USE, QUALITY AND DISTRIBUTION LOGISTICS
Abstract The reduction in the availability of fossil fuel increased the search for alternative fuel sources (for example, ethanol). In the Brazilian market, light duty vehicles can be fueled with gasohol (18 up to 27.5 %v/v of anhydrous ethanol in gasoline) and/or hydrous ethanol. To minimize the risk of water-induced phase separation of gasoline-ethanol ble

2. 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

3. Análise de desempenho de um motor ciclo Otto alimentado com álcool de 75 INPM / Otto cycle engine performance working with low alcohol content ethanol
Motor a álcool teve grande aplicação no Brasil com a implantação do Proálcool, programa lançada na década de 1970, vislumbrando reduzir a dependência externa do petróleo. Ressalta-se que avanços na tecnologia do referido motor, bem como na produção de álcool, tornaram-no técnica e economicamente viável como substituto da gasolina em algumas r

4. Aplicação da microscopia otica de fluorescencia ao estudo de polimeros e blendas polimericas de PVA/PVAc
A morphological study of polymer blends of 87-89% hydrolized PVA (124.000-186.000) and PVAc (high molecular weight) has been made using the relative compositions 9:1, 1:1 and 1:9, containing fluorescein (0,1% m/m). The formation of two phases, from a process of liquid-solid phase separation has been observed during the solvent(ethanol/water) evaporation The
