Caracterização e purificação de biocarvão advindo da indústria sucroalcooleira alagoana

Abstract

This work promotes the characterization and purification of two biochars derived from waste from the sugar and alcohol industry in Alagoas, from the Coruripe and Caeté plants, in order to understand their properties for future use in activities with greater added value, such as adsorbents of contaminants in effluents, catalytic supports, among others. The characterization process began with the separation of the waste by granulometry in order to study the different fractions individually and comparatively using sieves with mesh openings ranging from 28 to 200 Mesh. A purification of the biochar was also carried out in a system also developed in this work, which achieved 92% purification efficiency. Thermal characteristics were investigated through thermogravimetry and differential scanning calorimetry analyses, as well as spectrometric analyses that allowed the identification of compounds present in the samples and directed the development of the purification system.
