Brazil is the largest worldwide producer of alcohol and sugar from sugar-cane and has an extensive alternative program for car fuel which is unique. The objective of this work is to offer one management option of a solid residue produced by this industrial segment. The pressed sugar-cane bagasse is burned to produce steam and electricity by cogeneration.(More)
Sugarcane bagasse ash (SCBA) is a residue resulting from the burning of bagasse in boilers in the sugarcane/alcohol industry. SCBA has a very high silica concentration and contains aluminum, iron, alkalis and alkaline earth oxides in smaller amounts. In this work, the properties of sintered ceramic bodies were evaluated based on the concentration of SCBA,(More)
Some aluminosilicates, for example mullite and wollastonite, are very important in the ceramic and construction industries. The most significant glass-ceramic for building applications has wollastonite as the main crystal phase. In this work we report on the use of sugarcane bagasse ash (SCBA) to produce glass-ceramics with silicates as the major(More)
UNLABELLED Different inhalational anesthetics have various hemodynamic effects, either on the global circulation or on kidney perfusion. These drugs are also different concerning their potential for renal toxicity. The potential influence of the choice of the halogenated anesthetion in the outcome of kidney transplantation has not been previously studied,(More)
The complex development of crystals found in the crystallization of a SiO2-Al2O3-CaO-Na2O glass has been explained using Differential Thermal Analysis. The crystal growth process has been studied using isoconversional, invariant kinetic parameters and master plots methods. The applied kinetic models have revealed activation energy values that are over 360(More)
