1. Appliance of a high pressure semi-batch reactor: supercritical transesterification of soybean oil using methanol
Abstract This work presents the results of a supercritical transesterification process of soybean oil using methanol, performed in a laboratory high pressure semi-batch reactor. A full description of the equipment and a standard operating procedure are also provided. Since fossil fuels are not renewable, biofuels such biodiesel, have gained attention over t

2. Graphite and Nickel Containing Tin Bronze-Steel Bimetals as Lead Free Bearing Materials
Ni was added into graphite-lead free tin bronze composite layers on surface of steel sheets by primary sintering mixed powders of graphite and CuSn10 with addition of a nickel nitrate and poly(vinyl alcohol) (PVA) solution in an ammonia decomposition atmosphere. The reduced Ni particles attached on the surface of graphite and CuSn10 particles help to link th

4. Synthesis of biodiesel from transesterification os soybean oil by homogeneous and heterogeneous catalysis / Síntese de biodiesel a partir da transesterificação do óleo de soja por catálises homogênea e heterogênea
Biodiesel is defined as a mono alkyl ester of fatty acids of long chain derived from renewable sources such as vegetable oils and animal fats. Its importance is related to the use as an alternative fuel for diesel cycle engines. The biodiesel could be obtained by the transesterification reaction in which triacylglycerides (oil or grease) react with alcohol i

6. 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

7. Uso do óleo vegetal em motor estacionário de ciclo diesel / Vegetable oil use in stationary engine of diesel cycle
In terms of liquid biofuels, the questions related to alcohol are in a developed level with the creation of a productive chain where all the processes are technologically decided since the production of the sugar cane until the alcohol consumption with the development of the multifuel cars. As for the use of vegetable oils, some barriers must be overcome, ma

8. Metodologia experimental para a maximização do desempenho de um motor multicombustível turboalimentado sem prejuízo à eficiência energética global
The new trends of the automotive market require the development of a new concept of engines using different types of fuel, mainly those resulting from alternative sources of energy. Moreover, the multifuel engines available in the market display only one volumetric compression ratio, which leaves space for the development of systems that allow for different

9. Um Estudo de Politicas e Práticas do uso do GNV no transporte público urbano do Brasil / A study on policies and practices concerning the use of natural gas vehicle for the urban public transport in Brazil
The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, consider

10. Análise de ecoeficiência: avaliação do desempenho econômico-ambiental do biodiesel e petrodiesel. / Eco-efficiency analysis: environmental-economic assessment of biodiesel and petrodiesel.
Biodiesel is the most likely alternative to petrodiesel. It is composed of methyl or ethyl esters from fatty acids, obtained by a transesterification reaction between any triglycerides and an alcohol with short chain, methanol or ethanol. It has almost the same properties of petrodiesel, but comparing with this, it can eliminate the sulfur oxides emissions a

11. A desregulamentação e o desempenho do complexo sucroalcooleiro no Brasil.
This work analyzed the evolution of the relation between the sugar and alcohol complex and the State from 1975 to 2002, when there was a change from public intervention, marked by Proálcool, to a new situation, in which deregulation is proposed. We attempted to interpret the main political and economical stipulators of the process, as well as describe the w

12. Ensaio de um motor ICE a alcool com dupla ingnição / Testson a dual ignition alcohol SI engine
Os motores de combustão interna têm sido a principal fonte geradora de trabalho mecânico, especialmente em veículos automotores e sua quantidade tem se expandido de forma exponencial desde sua invenção, no século XIX. Os efeitos deste crescimento podem ser observados pelo aumento do consumo mundial de petróleo e da concentração de gases tóxicos na
