| This project aims to develop an enzymatic route for biodiesel production, using ethanol and palm oil as raw materials. Currently, biodiesel is obtained by a chemical reaction between an oil and an alcohol, accelerated by a chemical catalyst - mainly sodium hydroxide. The use of this catalyst, however, causes a number of problems, such as high energy consumption, difficult glycerol recovery and the generation of a large volume of effluent. In addition, it causes saponification when acid oils, suc Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2013 |
| The growing biofuel industry generates by-products that have shown promise as energy and protein feeds in ruminant diets. The objective of this project was to determine the effects of by-products of biodiesel production, obtained from different sources of oilseeds, on the in vitro degradability of nutrients, in vitro ruminal fermentation and methane gas production. Palisadegrass ( Brachiaria brizantha) was used as a model. Its isolated incubation was considered as a contro ... Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007 |
| The emission increase of greenhouse effect gases and the high petroleum prices have elevated the demand for renewable fuels. For diesel, the most used fuel in the country, the main option has been the use of vegetable oil and animal fat by-products. However, there are two major problems regarding the production of vegetal oils which could hinder the use of these products as fuel: the quality and the quantity of oils produced. Of all the cultivated species, only the palm oil has the needed produc Status: Completed Start date: Wed Dec 01 00:00:00 GMT-03:00 2010 |
| This is a broad research project on Barbados nuts, a crop with potential to become raw material for the production of biodiesel and aviation biokerosene. In spite of its high oil production, the plant has not been totally domesticated yet, that is, there are not different recommended cultivars or production systems for each region of the country yet. In this project, which is partially funded by Finep and CNPq, there are 22 participating research institutions in all Brazilian regions, 16 of whic Status: Completed Start date: Sun Aug 01 00:00:00 GMT-03:00 2010 |
| The project aimed to study the use of crude glycerin produced by biodiesel plants as feed for dairy cows as an alternative to reduce the use of maize, an energy source with increasingly higher international prices, and thus increase the sustainability of dairy production. Research work carried out in other countries suggests that glycerol is the main component of crude glycerin, an energetic nutrient efficiently used by ruminants. . Thus, this project considered three main strategies to address Status: Completed Start date: Wed Apr 01 00:00:00 GMT-03:00 2009 |
| Due to the crescent quest for renewable energy sources, the biodiesel production from renewable sources has created exceeding amounts of glycerol as a biodiesel sub-product. Currently, the most important consumer markets for glycerol are the industries of food, drinks, cosmetics, paper, ink, lubricants and resin. Thusly, studies that aim to find new uses, and open new consumer markets for glycerol have been strongly stimulated, and have been increasingly challenging scientists of practically all Status: Completed Start date: Wed Sep 01 00:00:00 GMT-03:00 2010 |
| As Brazil increases its production of biodiesel, so does the production of glycerin, a by-product with a high energy value. At the same time, corn, the main energy component in concentrated feeds, in addition to being the ingredient that most increases feed costs, tends to become less available in the market due to its use in the production of alcohol in Europe and the United States. Glycerol, the main component of glycerin, has already been used in some countries, mixed with concentrate for lac Status: Completed Start date: Mon Nov 01 00:00:00 GMT-03:00 2010 |
| The recent expansion of sugarcane's culture by the mid-southern states of Brazil (Paraná, São Paulo, Mato Grosso do Sul, Minas Gerais - except the north, and Goiás), has been mostly happening on areas where degraded grasslands occur, characterized by eroded soils which are poor in nutrients, under distinct hydric regimes in regions of traditional sugarcane production. The incorporation of these flat topography areas enables mechanized harvesting and a more intensive soil use, with the eliminatio ...

| The world production of oils extracted from the oil palm (Guinean Elaeis Jacq.) has grown by more than 300% in recent years. In Brazil, the crop underwent an expansion cycle, with an increase in the cultivated area from 103 thousand hectares in 2009 to 236 thousand hectares in 2016. Although 97% of production is destined for the food industry, there is a worldwide trend towards increased application of oil in new markets, including energy. Given the potential of the species as a producer of plan Status: Completed Start date: Fri Jan 01 00:00:00 GMT-03:00 2021 |
| The palm oil tree is, among the oilseeds, the most productive one, being able to reach an annual production of 10 tons/hectare in favorable conditions. The oil has many uses in food, pharmaceutical and chemical industries, and is also considered one of the best oils to produce biodiesel. In 2010, worldwide production of palm oil, cultivated in 14,99 million hectares, was of 45,09 million tons, while the production of soy oil, cultivated in 102,38 million hectares, was of 39,76 million tons.
