1. Continuous Synthesis of a Green Fuel Additive Mixture with Highest Quantities of Solketalacetin and Solketal and Lowest Amount of Diacetin from Biodiesel-Derived Glycerol
This work presents a continuous, easy-to-scale-up system for glycerol conversion to a valuable fuel additive mixture such as solketalacetin ((2,2-dimethyl-1,3-dioxolan-4-yl)methyl acetate), solketal and minimum amount of diacetin with no byproducts. A two-stage reaction was conducted to synthesize the mixture. At first, glycerol was reacted with acetic acid

2. Obtention and characterization of coconut babassu derivatives
Babassu (Orbignya sp.) is a palm with extraordinary socioeconomic and ecologic importance found in humid tropical areas in Brazil, especially in frequently burned and degraded landscapes. There are several uses for babassu oil; however, its potential for providing other industrial products remains unexploited, due to the lack of scale and production structur

3. 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

4. Conversion of by-products from the vegetable oil industry into biodiesel and its use in internal combustion engines: a review
Biodiesel produced from by-products and waste materials can be an economical way of reducing traditional oil consumption and environmental problems. The by-products from the vegetable oil refining industry such as soapstock, acid oil and fatty acid distillates are suitable for producing biodiesel. The present work is a survey related to the use of these by-p

5. Protein co-products and by-products of the biodiesel industry for ruminants feeding
The objective of the experiment was to classify 20 protein co-products and by-products of the biodiesel industry with potential to use in ruminant feeding. The meals evaluated were: cottonseed, canudo-de-pito, crambe, sunflower, castor-oil seeds detoxified with calcium, non-detoxified castor-oil seeds and soybean; and the cakes were: cottonseed, peanut, baba

6. Características da carcaça e dos componentes não-carcaça em ovinos alimentados com rações à base de farelo de mamona.
Objetivou-se avaliar o efeito da substituição do farelo de soja pelo farelo de mamona destoxificado sobre as características da carcaça e dos componentes não-carcaça. Foram utilizados 20 borregos, machos, com peso vivo de 19,3kg e 7 meses de idade, distribuídos aleatoriamente em quatro tratamentos de 0, 50, 75 ou 100% de substituição, com base na ma

7. Produção de monoéster via etanólise por hidrotalcitas termoativadas : síntese e caracterização
Among biofuels of the 1st generation, biodiesel stands out for its equivalent features to those of mineral diesel, however less polluting. It can be obtained by transesterification of triglyceride fats or vegetable oils by (m)ethanolysis. Aiming at improving the chemical process, different types of catalysis have been studied: i) homogeneous (acid e.g. H2SO4

12. The Composition a evaluate the polymer biodegradable produce for Burkholderia sacchari with the different substrates / Avaliação da composição de polímeros biodegradáveis produzidos por Burkholderia sacchari a partir de diferentes substratos
The bacterial production of polyesters belonging to the polyhydroxyalkanoate family (PHA) has generated biodegradable, biocompatible and environmentally friendly new materials. Properties and applications of PHA depend on monomer composition, which is dependent both on the substrate available and the metabolic apparatus of the PHA-producing microorganism. Bu
