13. Uso alternativo de glicerina em mistura com gasolina ou etanol em motores de ciclo Otto
O uso de biocombustíveis geralmente apresenta inúmeros benefícios, incluindo sustentabilidade, redução dos gases estufa, desenvolvimento regional, social e agrícola. Assim, o uso de biocombustíveis, como o biodiesel, é visto hoje como uma alternativa extremamente viável. O processo produtivo gera, em média, para cada tonelada (1000 kg) de biodiesel

14. Elaboración de recubrimientos cerámicos mediante proyección térmica por combustión a partir de residuos sólidos industriales
Ceramic coatings were elaborated onto carbon steel substrates by oxy-fuel thermal spraying process from catalysts waste used in petroleum refining. The adhesion and micro-hardness Vickers were evaluated according to ASTM C633-01(2008) and ASTM C1327-08 standards respectively, with adhesion values varying between 2,9 and 17,7 MPa and values of microhardness V

15. Employment of acoustic field for pollutant emission reduction under lean combustion
Pulsating combustion is a technique that directly intervenes in combustion processes modifying pollutant emissions and increasing thermal efficiency by varying pressure and temperature in the flame region. The pulsations accelerate mixture rate between oxidant and fuel, resulting in a more intense combustion process, with low fuel waste and potential for low

16. 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

17. ProduÃÃo de Ãcido CÃtrico utilizando glicerol residual da produÃÃo de biodiesel como substrato / Production of citric acid using residual glycerol from biodiesel production as a substrate
Due to government financial incentives, which boost the production of biodiesel, there has been a large scale production of this fuel. However, this growth has proved to be exaggerated, rising a worrying factor: the destination of the glycerol excess from biodiesel production. Such concern is clearly shown to prove an important fact: for every ton of biodies

18. Recovery of hydrocarbon liquid from waste high density polyethylene by thermal pyrolysis
Thermal degradation of waste plastics in an inert atmosphere has been regarded as a productive method, because this process can convert waste plastics into hydrocarbons that can be used either as fuels or as a source of chemicals. In this work, waste high-density polyethylene (HDPE) plastic was chosen as the material for pyrolysis. A simple pyrolysis reactor

19. Desenvolvimento sustentável na Amazônia: uma nova abordagem do dendê com o aproveitamento da biomassa residual para a geração de energia. / Sustainable development in the Amazon region: a new approach with the use of palm oil biomass waste to generate energy
This study examines the viability of a sustainable project with the production of palm (Elaeis guineensis) to supply oil to food or cosmetic industries and the use of the residual biomass as a biofuel by a power plant. The biofuel side of the project aims the provision of electricity in part of the so called Isolated System, in southern Roraima. The analysis

20. Obtenção de biodiesel a partir de resíduos gordurosos obtidos de gordura animal - vísceras de frango / Obtaining biodiesel from waste fat derived from animal fat - viscera of chicken
O foco principal do projeto foi estudar e avaliar os parâmetros da obtenção de Biodiesel tendo como matéria prima o resíduo gorduroso (OGR) obtido de gordura animal, particularmente a de frango. Os objetivos do projeto vão ao encontro de questões intimamente ligadas a área ambiental e socioeconômica que cercam a produção do biodiesel. Para isso, t

21. Pilhas de combustíveis microbianas utilizadas na produção de eletricidade a partir de rejeitos orgânicos: uma perspectiva de futuro
In this review is presented an innovative technology for use of animal and vegetable waste with high pollution levels in microbial fuel cell (MFC) as an alternative to waste remediation and simultaneously producing electricity and fertilizer for agriculture. A brief history of MFC, the studies about the electron transfer mechanisms, discussion of the biologi

22. Modelos estatísticos integrados à metodologia Lean Seis Sigma visando ao aumento da produtividade na obtenção do etanol / Statistical models integrated with Lean Six Sigma methodology in order to increase productivity in obtain of ethanol
The sugarcane is one of the most important economic businesses in Brazil, in both terms of trade balance and job opportunity. Alcohol (ethanol), obtained from sugarcane, is a fuel cleaner, because it contains oxygen in its composition and is used in vehicles powered by ethanol, on the composition of automotive gasoline and ex-fuel vehicles. Ethanol burning p

23. Assessment of the consequences of the concrete production in Brazil for the climate change. / Avaliação das conseqüências da produção de concreto no Brasil para as mudanças climáticas.
The Brazilian concrete sector contributes to the climate change due to its CO2 emissions, that can be reduced through efforts of the cement sector, that have been receiving great attention. But the use of the cement in concrete can increase its consumption if made in the wrong way, and this can increase the CO2 emissions, making important the study of the em

24. THE USE OF BIO-DIGESTERS IN SMALL AND MEDIUM RURAL PROPERTIES WITH EMPHASIS ON VALUE ADDING: A CASE STUDY FROM NORTHWESTERN REGION OF RIO GRANDE DO SUL STATE / O USO DE BIODIGESTORES EM PEQUENAS E MÉDIAS PROPRIEDADES RURAIS COM ÊNFASE NA AGREGAÇÃO DE VALOR: UM ESTUDO DE CASO DA REGIÃO NOROESTE DO RIO GRANDE DO SUL
From the duration of the Kyoto Protocol, there has been a renewed interest in technology of bio-digesters. As they allow a reduction in the emission of greenhouse gases compared to other waste treatment methods, their deployment can permit the marketing of carbon credits, resulting in money. The present study aims to analyze the process of dissemination of t
