2. INCREASED ENERGY COGENERATION IN THE SUGAR-ENERGY SECTOR WITH THE USE OF SUGARCANE STRAW, ELECTRIFICATION OF DRIVES, AND HIGH-DRAINAGE ROLLERS IN THE EXTRACTION
ABSTRACT The sugar-energy sector stands out in the production of electrical energy in the Brazilian energy matrix. The updating of Law 9,427 allowed increasing the limit of power injected in the transmission or distribution systems of existing projects from 30 to 50 MW, encouraging studies of expansion and/or implementation of new cogeneration projects. This

6. MicrogeraÃÃo de energia elÃtrica com gÃs de sÃntese de um gaseificador concorrente utilizando ItaÃba mazilaurus / Microgeneration of electricity with syngas from a downtraft gasifier using ItaÃba mazilaurus
The use of biomass as energy source is one of the most promising, because it contributes to reduce emissions of carbon dioxide in the atmosphere and allow the decentralized energy generation. Gasification is a technology of processing biomass energy into a gaseous biofuel of low calorific value. The gas can be used in Otto cycle engine for power generation i

7. Caracterização de biomassas brasileiras para fins de aproveitamento energético / Characterization of brazilian biomasses for energy recovery
New energetic alternatives have been the subject of discussion about conservation of natural resources. Such discourses are based mainly on reducing emissions of greenhouse gases and other pollutants, caused mostly by the use of fossil fuels, major source of energy today. In view of the applicability of biomass as energy input, this paper presents an experim

9. Estudo das condições de estocagem do bagaço de cana-de-açúcar por análise térmica
An evaluation was made of the properties of sugarcane bagasse during the storage process for subsequent burning in a boiler. Samples of bagasse were collected over a period of 150 days from the Caeté sugar mill (MG) at various points of the stockpile soon after the sugarcane was pressed to extract its juice, as well as from natural bagasse, dry and damp.

10. Medidas da emissão de poluentes e da eficiência na combustão assistida do glicerol residual de biodiesel. / Measurements of emissions and fuel efficiency of the assisted residual glycerol biodiesel.
With increased global production of biofuels in particular biodiesel, an excess of glycerol is being generated worldwide. This has caused a sharp drop in the price of this compound in the world market. Much thought has been given to a destination for this residue, since no one can lay it in the environment and one of the alternatives be to use would its calo

12. Use of Jatropha oil methyl ester and its blends as an alternative fuel in diesel engine
Biomass derived vegetable oils are quite promising alternative fuels for agricultural diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the transesterification process. In the present
