2. Quantification and qualification of exhaust gases in agricultural diesel engine operating with biodiesel mixtures
RESUMO Motores de ciclo diesel são amplamente utilizados em máquinas agrícolas. O biodiesel oferece a possibilidade de substituição parcial ou total do diesel mineral, reduzindo assim a dependência da agricultura desse recurso não renovável e diminuindo as emissões de poluentes. O objetivo deste estudo foi avaliar as emissões de CO, NOx, SO2, CO2 e

3. Evaluation of CO2 Biofixation and Biodiesel Production by Spirulina (Arthospira) Cultivated In Air-Lift Photobioreactor
ABSTRACT Spirulina is a microalgal genre that has the capacity to produce various bioproducts with applications in several areas including the energy sector. The study aimed to assess the ability of CO2 biofixation, biodiesel and other biocompounds production by Spirulina sp LEB 18 cultured in air-lift photobioreactor. The microalgae presented a rich macronu

4. A simulation study about the impact of biodiesel use on the atmosphere of Rio de Janeiro city
Abstract This study evaluates the impact of biofuels on the air quality of the city of Rio de Janeiro using an air quality model based on the trajectory model OZIPR associated with the SAPRC chemical model. The results show that the increase in biodiesel use reduces ozone levels in the atmosphere by 10.2 %, using Biodiesel with Ethanol and Diesel mixture (BE

5. Correlation Between the Composition and Flash Point of Diesel-Biodiesel Blends
Methyl ester biodiesels from vegetable oils, including soy, corn, canola and sunflower, and from swine lard, were prepared. They were mixed with mineral diesel to produce blends from 5% v/v to 50% v/v of biodiesel, i.e., B5, B10, B20 and B50. The flash points of these mixtures, the pure diesel (B0) and the pure biodiesel (B100) were determined. In all cases,

6. Potencial da extraÃÃo de Ãleo de peixe para produÃÃo de biodiesel / Potential extraction of fish oil for biodiesel production
Energy issues have been discussed intensively in the search for alternative energy sources, environmentally friendly and sustainable, since the prospect of depletion of fossil fuel reserves are eminent, thus reviving attention to alternative energy sources, among them, biofuels. Fish oil shows up as an alternative technology for the recovery of waste from pr

7. Produção de biogás a partir de glicerol oriundo de biodiesel / Biogas production from glycerol generated on biodiesel industry
The Brazilian legislation demands the use of biodiesel mixed with diesel in an increasing rate. This raise on biodiesel production implies also on an increase on generation of glycerol, which is a liquid or semi-solid waste with high concentration of salts (approximately 46.1 g\ CL POT.-\ /L) and organic matter (1260 gCOD/L in average). Despite being widely

8. Avaliação das propriedades físico-químicas do biodiesel de soja, algodão e mamona e da mistura de biodiesel de soja e algodão / Evaluation of physico-chemical biodiesel from soybeans, cotton and castor oil and the mixture of biodiesel from soybeans and cotton
Uma das maiores atividades humanas que gera impacto ao meio ambiente é o setor de transportes automotores, especialmente veículos que utilizam óleo diesel mineral como forma de combustível. Independente do conforto ou objetivos que levem a utilização deste tipo de transporte, estes produzem emissões que contém diversos tipos de poluentes atmosférico

12. Metodologia analítica para quantificar o teor de biodiesel na mistura biodiesel: diesel utilizando espectroscopia na região do infravermelho
Considered the best substitute for diesel, biodiesel can be blended with diesel in any ratio, bringing lots of environmental, economic and social advantages. Brazilian law Nº 11097/2005, proposes the introduction of biodiesel in to the Brazilian energy matrix, mixed with diesel at a minimum percentage of 2%. For consumers and sellers to be sure that the com
