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. DESEMPENHO EM DINAMÔMETRO E EMISSÕES RESIDUAIS DE UM MOTOR DE TRATOR AGRÍCOLA OPERANDO COM MISTURAS BINÁRIAS DE ÓLEO DIESEL B5 E BIODIESEL DE ÓLEO DE FRANGO / PERFORMANCE IN DYNAMOMETER AND EMISSIONS OF WASTE AN AGRICULTURAL TRACTOR ENGINES OPERATING WITH BINARY MIXTURES B5 DIESEL AND BIODIESEL OIL CHICKEN
Brazil, the third largest producer of biodiesel in the world, and also the third largest producer of chicken, may increase in some regions, the use of oil derived from birds, as an alternative to fossil fuels. In order to increase the range of options to reduce dependence on soybean oil for that purpose, and fostering environmental aspects, it is possible to

3. Use of Jatropha oil methyl ester and its blends as an alternative fuel in diesel engine
Biomass derived vegetable oils are quite promising alternative fuels for agricultural diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the transesterification process. In the present

4. ÉSTERES COMBUSTÍVEIS EM MOTOR DE CICLO DIESEL SOB CONDIÇÕES DE PRÉ-AQUECIMENTO E VARIAÇÃO NO AVANÇO DE INJEÇÃO / ESTERS FUELS IN DIESEL ENGINES UNDER PRE-HEATING CONDITIONS AND VARYING INJECTION TIMING
The renewed interest in energy for biomass is supported by the need for different energy sources and the need to protect the environment. Recently, because of increases in crude oil prices, limited resources of fossil oil and environmental concerns there has been renewed focus on vegetable oils and animal fats to make a biodiesel fuel. What is known as biodi

5. CONTROLADOR NEBULOSO PARA MOTOR DE IGNIÇÃO POR COMPRESSÃO OPERANDO COM GÁS NATURAL E ÓLEO DIESEL
A foreseeable shortage of petroleum, associated to a growing ecological conscience, demand for alternative sources of energy and more efficient and less pollutant combustion processes. Among the few pollutant fuels this work approaches the combination of natural gas, whose consumption has been increasing year to year, and diesel. It is known that the interna

6. ANÁLISE DE UM SISTEMA DE PRODUÇÃO SIMULTÂNEA DE ELETRICIDADE, FRIO E CALOR / ANALYSIS OF A SYSTEM FOR THE SIMULTANEOUS PRODUCTION OF ELECTRICAL ENERGY, HEAT AND COLD
The simultaneous production of electric energy, heat and cooling capacity from the primary fuel burning on a heat engine (trigeneration) can emerge as a promising strategy, from the energy and project points of view, mostly, in food and chemistry industries. The present work describes the experimental study of a vapor compression system for chilled water pro

7. Elementos de suporte do comando de valvulas avaliado por modelo de diferenças finitas
The Valve Train System used in combustion engines have the ability to command the opening and closure of gas circulation valves control that takes part in combustion. It is formed by many sub-systems. One of these systems is the finger follower/pivot contact, where the command starts the finger follower for valve starts and uses the pivot as a support elemen

9. Nonthermal plasma reactors for the production of light hydrocarbon olefins from heavy oil
During the last decade, nonthermal plasma technology was applied in many different fields, focusing attention on the destruction of harmful compounds in the air. This paper deals with nonthermal plasma reactors for the conversion of heavy oil into light hydrocarbon olefins, to be employed as gasoline components or to be added in small amounts for the catalyt

11. Nonlinear natural engine: Model for thermodynamic processes in mesoscale systems
To develop intuition on the possible application of concepts from thermodynamic heat engines to mesoscale systems, we have constructed and studied a model thermoacoustic heat engine. The model consists of a chain of coupled nonlinear acoustic vibrators in which the primary thermodynamic medium is argon gas, the secondary thermodynamic medium is constituted b
