Evaluation of the Thermic Behavior of the Coal as a Byproduct through the Low Temperature Conversion Process – LTC of the Sewage Sludge

Abstract:

Brazil follows the global trend to seek viable alternative energy sources that can improve the quality and secure supply of energy with environmental sustainability, allied to the necessity of facilitating a fitting end to the sludge treatment plants sewage. The biomass present in SS is emerging as an alternative to the country's energy matrix, through the Low Temperature Conversion process – LTC of the sludge in the production of biofuel (biooil and coal). This article aims to characterize the coal obtained through the Low Temperature Conversion and evaluate the thermal behavior. In this study physical and chemical studies were made: elemental analysis (CHNO), calorific power, Thermogravimetry (TG) at a heating rate of 10°C min-1 under synthetic air atmosphere, and spectroscopic. The thermogravimetric study found a thermal stability at 300oC. In the spectroscopy in the infrared (IR) regionit was observed bands related to the presence of water, organic matter and silicon oxides in the SS samples analyzed.
