Produção de biochar a partir da pirólise de resíduos agroindustriais

Abstract

Lignocellulosic residues, found abundantly throughout the country, they have been used as a source of biomass for themselves in the energy scenario, socioeconomic and environmental of the country, due to its composition and its higher added value. Among the forms of transformation of biomass, pyrolysis is a viable alternative has been used to produce liquid products (bio-oil), solid (biochar) and gas (biogas). The pyrolysis process can be defined as the thermal degradation of organic material in total or partial absence of oxygen at high temperatures. One of the featured products in this process are the bio-carbon (biochar), a product which has important applications as adsorbent for the treatment of wastewater, removing metallic dyes and other pollutants, making the patch of soil (fertilizer) and promotes retention nitrogen, sulfur, phosphates, calcium and organic matter in the soil. Thus, it is expected that alternative energy system to be generated through the use of lignocellulosic residues, as well as the diversification of the potential of the feedstock in the generation of products with industrial interest.
