13. Scrap tire ashes in portland cement production
Scrap tires are not considered harmful waste, but their stocking and disposal are a potential health and environmental risk. Properly controlled calcinations at high temperatures make tire combustion an interesting alternative due to its high calorific power, comparable to that of fuel-oil. Consequently, using them as an alternative combustible material in c

14. Simulação numérica da separação de misturas CH4/He e CO2/He em colunas de adsorção em leito fixo
Methane and carbon dioxide gases are part of natural gas composition and methane is in bigger proportion. Both gases are pollutants which methane is the most responsible by the greenhouse effect and carbon dioxide in turn by pipelines oxidation in natural gas transporting. The separation of CO2 from natural gas promotes an increase in calorific power of the

18. Desempenho de motor Ciclo diesel em bancada dinamomÃtrica utilizando Biodiesel etÃlico de soja / Performance of engine cycle diesel in dynamomÃter using mixtures diesel/biodiesel
Ahead of the forecast of scarcity of the oil, the ethyl ester (biodiesel) if has presented as an excellent alternative fuel option for engines cycle diesel. The characteristics of biodiesel are similar of diesel in terms of viscosity and the calorific power, being able to be used without adaptations in the engines. For accomplishment of this work, a motor cy
