1. Agricultural tractor performance fueled with proportions of biodiesel
ABSTRACT Among the fuel sources used nowadays, biofuels stand out for being renewable and biodegradable. In this sense, this work aimed to evaluate the performance and smoke opacity of an agricultural tractor in soil tillage activities, depending on the biodiesel blends and the engine rotation. Were used six blends of soy (S) and murumuru (M) biodiesel and s

2. OXIDATIVE STABILITY AND COLD FILTER PLUGGING POINT OF BIODIESEL BLENDS DERIVED FROM FATS AND SOY OIL
Biodiesel made from oils is rich in polyunsaturated fatty acids methyl esters, and, consequently, presents high tendency to oxidize. Biodiesel made from fats, on the other hand, is mainly comprised by saturated chains. Although it is highly stable, they easily crystalize at low temperatures. Blends from both can exhibit optimized properties. In this work, ox

4. Binary Blends of Biodiesel from Macauba (Acromia aculeata) Kernel Oil with Other Biodiesels
Macauba is a palm tree which provides large amount of oil. Particularly its oil from the kernel presents excellent stability to oxidation as it is mainly constituted by saturated organic chains. This stability is inherited by the biodiesel prepared with this oil. Paradoxically, contrarily to the expectation as it is mainly constituted by saturated esters, th

5. GC-FID METHODOLOGY VALIDATION FOR THE FATTY ESTERS CONTENT DETERMINATION IN BIODIESEL WITH HEXADECYL ACETATE AS THE INTERNAL STANDARD
Biodiesel purity expressed as fatty esters content is one of its most important quality parameters. Although several instrumental methods have been employed, gas chromatography with internal standard calibration has been the most used. Biodiesel is a very complex matrix, therefore finding a suitable internal standard (IS) is not straightforward. EN14103:2003

6. The Use of the Liquid from Cashew Nut Shells as an Antioxidant in Biodiesel
The influence of cashew nutshell liquid (CNSL) in the oxidative stability of biodiesels prepared from oils of soy, corn, canola and sunflower was studied using the Rancimat method. The induction periods at 110 ºC, without and with the addition of CNSL at concentrations of 0.1, 0.5 and 1.0% m/m, were determined and clearly show an important increase in the o

7. Influence of Water and Ultraviolet Irradiation on the Induction Period of the Oxidation of Biodiesel
Biodiesel degrades due to oxidative processes, causing a decrease in its quality. In the present work, it has been clearly shown that the incidence of ultraviolet radiation on biodiesels obtained from soy, canola, linseed and microalgae oils initiate oxidative processes which lead to the decrease in the induction period (IP) of the fuel. The influence of the

8. 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,

9. Energy utilization of by-products from the soybean oil industry by broiler chickens: acidulated soapstock, lecithin, glycerol and their mixture
Acidulated soy soapstock (ASS) and lecithin (LEC) are by-products from processing soy oil (SO) for human consumption, whereas glycerol (GLY) can be obtained through the transesterification of vegetable oils during the production of biodiesel. These are valuable by-products for poultry feeds that have been underutilized in many parts of the world. One study w

10. Divergência genética e eficiência do uso do fósforo na soja visando à produção de biodiesel
A cultura da soja tem papel importante na questão do biodiesel, por apresentar potencial produtivo e viabilidade técnica capaz de atender parte da crescente demanda por combustíveis renováveis. No ano agrícola 2009/10, foram realizados quatro ensaios de competição de cultivares de soja, sendo dois no Campus Universitário de Palmas e outros dois no Ca

11. A competitividade da produção de biodiesel no Brasil: uma análise comparativa de mamona, dendê e soja
A possibilidade de diversificação na produção de matérias-primas utilizadas para fabricar biodiesel favorece a competitividade brasileira. Contudo, os custos atuais de produção de biocombustíveis, em todo mundo, são pouco competitivos em relação aos dos derivados de matérias-primas fósseis. Considerar somente aspectos relacionados às questões

12. Avaliação das propriedades físico-químicas, fluidodinâmicas e oxidativas do biodiesel de licuri (Syagrus coronata) e das blendas (Licuri/Soja). / Evaluation of Physical-Chemical, Fluid dynamics and Oxidative Properties of the Licuri palm nuts Biodiesel and Blends (Licuri/Soy).
Este trabalho relata as propriedades físico-químicas, fluidodinâmicas e oxidativas do biodiesel de licuri (Syagrus coronata), visando tornar esta oleaginosa uma fonte alternativa de biocombustível no semi-árido nordestino. Objetiva também as análises das blendas de biodiesel metílico de soja e licuri (BSLX) quanto à correção das propriedades de es
