1. Avaliação de biocombustível derivado do bio-óleo obtido por pirólise rápida de biomassa lignocelulósica como aditivo para gasolina
A biofuel was prepared from acid aqueous fraction (pH = 2) of bio-oil produced by fast pyrolysis (Bioware Technology) of lignocellulosic biomass (sugar cane residue) and tested in blends (2, 5, 10 e 20% v/v) with gasoline type C (common) marketed in Brazil. The specification tests made in the Refinery President Getúlio Vargas (PETROBRAS) showed increasing i

3. Limites e possibilidades de desenvolvimento da cadeira produtiva do álcool: um estudo de caso no Rio Grande do Sul
The actual energetic context is characterized by environmental problems caused by de industrial developing and by the high value of oil (energetic base of the developing model) witch leads us to the search of alternatives (renewable energies), that may complement or replace the actual existing energy chain. In this reality the development in Brazil is remain

4. SIMULTANEOUS METAL DETERMINATION IN COMBUSTIBLE ALCOHOL USING ANODIC VOLTAMMETRY OF RENEWABLE IN ACID WAY / DETERMINAÇÃO SIMULTÂNEA DE METAIS EM ÁLCOOL COMBUSTÍVEL UTILIZANDO VOLTAMETRIA DE REDISSOLUÇÃO ANÓDICA EM MEIO ÁCIDO
O Brasil é pioneiro no uso de etanol como combustível. Trata-se de um combustível renovável que vem contribuindo para reduzir os níveis de emissão de CO2 na atmosfera, mas que apresenta contaminantes tais como os metais Zn, Cu, Cd, Fe, Cl, Ni, Co e Pb. A presença de metais pesados em etanol combustível é oriunda das diferentes etapas de produção e

5. Intraempreendedorismo no desenvolvimento de produto de seguro para usinas de açúcar e álcool.
The intrapreneurship can be defined as the capacity that the employees of an enterprise has, among others, to promove the inovation inside the organization acting as true entrepreneurs, but with a freedom of action a little restrict, because they are not the owners of business. One of the objectives of an intrapreneur action can be conduct the company to rea

6. Classificador de qualidade de álcool combustível e poder calorífico de gás GLP. / Alcohol combustible quality and LPG gas calorific power classifier.
This work shows the results of a robust system development as an alternative to recognize the quality of an alcohol fuel vapor sample and Liquid Petrol Gas (LPG) heat power in an electric nose. Two experimental methodologies were implemented to extract the features of alcohol fuel vapor and LPG gas patterns. The first approach to process the data used an Fuz

7. A emergy analysis of trends in sugar cane sector / Uma analise emergetica de tendencias do setor sucroalcooleiro
With the first crisis of the oil, in 1973, it had necessity to search alternative energy sources that could substitute the oil derivatives. Thus, the Alcohol National Program ? ProÁlcool ? was instituted with the emission of the Decree n° 76,593, of November 14, 1975, being based, initially, in the anhydrous alcohol production to be mixed to gasoline. With

8. Desenvolvimento sustentavel : uma analise do alcool como alternativa energetica
World energetic matrix based on combustible fossils, more importantly oil has shown signs of unsustainability. The reasons for this are related to both production structure, which needs to be diversified as to incorporate new sources of energy, and also to the actual pattern of consumption. There is plenty of evidence to suggest that humankind evolution will
