| This work evaluated the effective and potential importance of biodiesel for soybean production in Brazil and its regions in 2008, as well as if the prices of biodiesel had been adjusted according to the interests of producers and consumers. Four situations were considered: the first one refers to the application of Law 11.097/05, which resulted in a production of 1.164,33 million liters of biodiesel (912,83million liters of soybean biodiesel), which corresponds to 2,6% of the national diesel consumption in 2008. Alternatively, an estimate was made of what would happen if the percentage of the mixture had been 4%, 5% or 8,3%. In 2008, it is estimated that 8,5 % of the soybean produced in Brazil was directed for biodiesel production, and this percentage... |

| The bacterial diversity in a diesel contaminated tropical soil was investigated using diesel oxidation in gradient cultures dynamics (pH and OD) of the pure cultures. The diesel dependent growths of these isolates were assessed for 15 days by monitoring the gradient fluxes in the pH and Optical density OD of the media. Results showed an increase in OD as well as fluctuations in pH values. The mean OD data obtained was 0.515- 1.187 with pH of 6.95-7.2. From the morphological and biochemical characterization and comparison with respect to the standard references, the isolates S1P1, S3P3, S2P2, S2P1,and S3P2 were presumably the members of the genera Bacillus, Pseudomonas and Mycobacterium species. From the study, it was apparent that the tropical ecosystems... |

| ABSTRACT The tariff flags on Brazil came into force in January 2015, applied to all electrical distribution agents of the national interconnected system (SIN) and all final consumers are being charged for this new model. Given this, the cost of electricity in irrigation suffered representative additions involving searches of alternatives, such as the use of diesel engines. This study aimed to analyze the costs and the total annual costs of pumping with diesel and electric operation in 3 regions of Brazil, considering the application of the tariff flags. We concluded that the Southeast region (SE) features an hourly cost of electricity above the Central-West (CO) and the Northeast (NE) regions at any adopted tariff, regardless of the time of pumping and the... |

| The purpose of the present study was to estimate emissions of some pollutants (CO, NOX, HC, SOX, and PM) in diesel fleet due to the addition of biodiesel in different blends, as well as to assess atmospheric pollutant concentrations in the metropolitan area of Porto Alegre (MAPA). The methodology was based on inventories from mobile sources based on US EPA's technical report. Regarding air quality the following parameters were determined: PM10, PM2.5, CO, NOX, O3, SO2, HC and PAHs. The results showed a decrease for emissions PM, CO, and HC, and a slight increase for NOX. The characterization of atmospheric pollutants in the metropolitan area of Porto Alegre showed that they are influenced by mobile sources, particularly diesel vehicles. The diagnosis of... |

| O biodiesel tem sido considerado como o mais promissor dos produtos na busca por combustíveis alternativos para o segmento de transportes, de cargas e passageiros. O setor espera que em 2014 seja comercializado um volume pelo menos 16% maior do que em 2013, taxa projetada pelo aumento da mistura de biodiesel no diesel fóssil, de 6% (B6) para 7% (B7) em volume, já aprovado pelo governo. A fim de alinhar fatores econômicos com benefícios socioambientais aonde vem sendo produzido, faz-se necessário que a produção seja sustentável, proveniente de novos cultivares de oleaginosas. Neste trabalho procurou-se investigar o futuro do biodiesel no país, observando dados divulgados pela Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (ANP) e barreiras para... |

| Tranesterification reaction was carried out on raw Shea Butter Oil (SBO) and Palm Kernel Oil (PKO) to separate the ester from glycerol using ethanol in the presence of potassium hydroxide as catalyst. The properties of biodiesel (ethyl ester) obtained from varying proportions of diesel were experimentally determined and compared with that of conventional diesel. The fatty acid profile of the oil samples were determined using standard methods. Four blends (10, 20, 25 and 30%) of SBO and PKO by volume with diesel oil were produced and fuel properties determined include viscosity, relative density, specific gravity, flash, cloud and pour points. Mean values of the six fatty acids (palmitic, stearic, oleic, linoleic) obtained for shea butter and palm kernel... |
