1. Synthesis of Triacetin and Evaluation on Motor
Triacetin (or glycerol triacetate) was obtained by acetylating the glycerol by-product of biodiesel production process. This procedure is an interesting alternative that follows the principles of green chemistry. In this work, triacetin was synthesized using reactions between glycerol and acetic acid, as well as glycerol and acetic anhydride, using homoge

2. IDENTIFICATION OF THE BEHAVIOR OF TEMPERATURE MAIN RECTIFIER OF A DIESEL-ELECTRIC LOCOMOTIVE / IDENTIFICAÇÃO DO COMPORTAMENTO DA TEMPERATURA DO RETIFICADOR PRINCIPAL DE UMA LOCOMOTIVA DIESEL-ELÉTRICA
In this dissertation, we explore the application of the Theory of System Identification to develop a mathematical model that represents the behavior of the electrical current rectifier used to power the traction motors of a locomotive diesel-electric, based on mathematical manipulation of its temperature data. It was developed an ARX model and, using the aid

3. REDUCTION OF THE EMISSIONS IN GAS DIESEL GENERATORS / REDUÇÃO DAS EMISSÕES EM GERADORES DIESEL-GÁS
The objective of this study is converting a generator, originally Diesel, to operate in a Diesel-Gas; two fuels are administered simultaneously to the motor. One diesel generator of 120KW model Perkins 1006 TAG (powered with turbo intercooler), running on the Diesel / natural gas dual fuel mode, was tested. Experimental measurements were performed in both th

4. Development of ammonia-water absorption refrigeration systems simulator and its application in a project of a system moved by exhaust gases of diesel engine / Aperfeiçoamento de um simulador de sistemas de refrigeração de absorção agua-amonia e sua aplicação para projeto de um sistema movido a gas de escape de motor diesel
This work shows the development of an ammonia-water absorption refrigeration system pre-existing simulation program, which uses diesel engine exhaust gases from a diesel-generator group as energy source. The project was implemented in four stages. An initial design of its components involved solely thermodynamic relations, and was based on the arbitration of

5. Otimização de sistema de bombeamento com energia eólica: sistema de bombeamento de São Gabriel/BA
A partir do Protocolo de Kyoto e da ECO 92- Rio de Janeiro, as atenções do mundo estão voltadas para a preservação do meio ambiente e do uso sustentável dos recursos naturais, preservando-os para as gerações futuras. Desde então, buscam-se soluções para o suprimento de energia nas suas mais conhecidas formas e a substituição do uso de combustív

6. 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

7. Attendance of electric power residence for isolated communities of low potency of the interior of the state of Pará through a gaseifier of 1kw / Atendimento de energia elétrica domiciliar para comunidades isoladas de baixa potência do interior do estado do Pará através de um gaseificador de 1kw
In Pará State, almost 21% of its population has no access to use of electric energy in their residence. To this universe belongs the target audience from this report, that are the isolated communities. Due the large territorial extension and hydrographic basin in Pará State, this communities will have many difficulties to be served by the extension of dist

8. Biodiesel de soja: taxa de conversão em ésteres etílicos, caracterização físico-química e consumo em gerador de energia
Biodiesel was produced by the transesterification of neutral soybean oil and anhydrous ethanol using NaOH as catalyst. Combinations of biodiesel and diesel in the proportions of 0, 5, 10, 20, 40, 60, 80 and 100% were tested, respectively, as fuel in an energy generator. The average consumption and mixture performance were analysed. The tests showed a reducti

9. Supervisão de um sistema hibrido eólico/diesel usando lógica Fuzzy / Hybrid system wind/diesel supervision using Fuzzy logic
O presente trabalho sugere um modelo de supervisão para um sistema de geração hibrido em regiões isoladas do estado de Mato Grosso do Sul. O problema de regiões afastadas e sem atendimento de energia elétrica por intermédio de linhas de transmissão está sendo resolvido através de sistemas hibridos de energia, os quais são compostos por uma fonte c

10. 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
