Uso de biomassas como possíveis fontes renováveis para aplicação da indústria siderúrgica

Abstract

Due to the growing demand for renewable energy sources, charcoal together with biomass has been standing out on the world stage as alternatives to fossil fuels. Brazil is the world's largest producer of charcoal and its main consumer market is the steel industry. The present work was carried out from bibliographic reviews on the biomasses of elephant grass, babassu coconut, coconut-bay and sugarcane and was divided into three stages. Initially, the national productive capacity of biomass was surveyed, and it was found that the productive capacity of babassu coconut and coco-baía are not sufficient to meet national demand, unlike elephant grass and sugarcane, which have the capacity and technology needed. In the second stage, the parameters of fixed carbon content, ash, volatile materials and calorific value were raised and discussed. At this stage, it was evidenced that the biomasses have excellent properties and can be used as alternative sources to coke. Finally, the main challenges in the implementation of charcoal were investigated and it was concluded that the high costs of logistics, implementation and restructuring of the charcoal production chain are still impediments to the implementation and popularization of charcoal.
