13. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

16. Agricultura familiar e expansão da cana-de-açúcar sobre áreas de culturas anuais no Estado de Goiás a partir da safra 2005/06 / Family farming and sugarcane expansion over areas of annual crops in Goiás State from the 2005/06 harvesting season
Sugarcane ethanol, considered a major source of clean energy, is an option for changing the energy matrix of Brazil and also the world, contributing to the reduction in consumption of fossil fuels. In Brazil, Goiás State is one of the sugarcane expansion s frontiers to meet the growing demand for biofuels. But this expansion means sugarcane mills could take

17. Modelagem de equilíbrio líquido-líquido, líquido-vapor e líquido-líquido-vapor para sistemas binários, ternários, quaternários e pseudo-quaternários, envolvendo a produção de biodiesel / Modeling of liquid-liquid, liquid-vapor and liquid-liquid-vapor equilibria for binary, ternary, quarternay and pseudo-quaternary systems involving biodiesel production
The worldwide energy demand increases every year. This demand will reach levels that cannot be supplied by current conventional fossil fuel resources. In this context, biofuels arise as a growing primary source of energy, raising research opportunities and encouraging technology development. An important technical issue related to biofuels development is the

18. Produção de cana-de-açúcar para obtenção de etanol hidratado no Rio Grande do Sul : uma análise utilizando dinâmica de sistemas
Brazilian use of sugar cane ethanol in its energy matrix has been gaining international recognition. With a growing fleet of flex fuel vehicles, Brazil has been building an each year greater demand for ethanol. Nevertheless, consumption levels throughout the country are not homogeneous. Far from sugar cane production centers and with one of the nations highe

19. Desenvolvimento e otimização de processos de produção de etanol de primeira e segunda geração e eletricidade a partir da cana-de-açúcar / Development and optimization of first and second generation bioethanol and electricity production processes from sugarcane
Increase on biofuels demand has motivated the production of bioethanol from lignocellulosic materials (2nd generation ethanol). Bioethanol has been produced in large scale in Brazil from sugarcane (1st generation ethanol) for more than 30 years. Large amounts of lignocellulosic materials (bagasse and trash) are generated during sugarcane processing; bagasse

22. The impact of power supplied by the ethanol reformer and fuel cell : a scenary for promotion of the social and environmental development of the community of "Pico do Amor"/ MT / O impacto da energia eletrica proveniente do reformador de etanol e celula a combustivel : cenario para a promoção do desenvolvimento socioambiental da comunidade "Pico do Amor"/MT
The energetical planning of isolated communities has been trying to attend only the residential electrical energy demand. However, taking into account the family financial low level, this population characteristic, it is believed that the electrical energy should be directed for other specific goals: the execution of productive activities to promote the soci

23. Cultivo de bactérias redutoras de sulfato (BRS) e sua aplicação na biorremediação de efluentes ácidos contendo metais
Sulfate Reducing Bacteria (SRB) can be used as a promise and attractive biotechnology based alternative to promote passive treatment of industrial effluents. Sulfate is reduced to sulfide while organic matter is oxidized producing carbonate and bicarbonate ions. Treatment efficiency however depends on pH and metals content of the selected effluent and also o
