1. Efectos del uso de electrolitos soportes en ensayos electroquímicos de la aleación Al-4%Mg expuesta a bioetanol combustible
ABSTRACT The growth of world energy demand directly affects the consumption of petroleum-based fuels, increasing the negative impact of the use of these fuels and the decrease of crude oil reserves. This creates an opportunity for the use of fuels that are more efficient, of low environmental impact and, above all, of a renewable nature. Bioethanol is a biof

9. GaseificaÃÃo de materiais lignocelulÃsicos para geraÃÃo de energia elÃtrica / Gasification of lignocellulosic materials for generation of electric energy
The gasification of solid fuel as biomass can be defined as the transformation of it into a combustible gas. This gas is made up of a mixture of carbon monoxide, hiydrogen, metane, small amounts of other light hydrocarbonetes, carbonm dioxide and water vapor, in addition to nitrogen, which is presetn in air. The objective of this work was to built a contercu
