Produção, otimização e análise de briquetes de biocarvão oriundos da pirólise

Abstract

The work aims at the production, optimization, and analysis of biochar briquettes generated through the vacuum pyrolysis of Ouricuri (Syagrus coronata) residues. Many studies show that 25% of the waste generated could be used for the production of bioenergy and it is estimated that in 2030, both agricultural and forestry production should undergo a substantial increase, resulting in higher amounts of waste. Pyrolysis gained prominence for generating products such as: bio-oil, biogas, and biochar, adding value to the residual biomass, reducing the volume of waste, and as a consequence, reducing the environmental impact. In this context, the application of biochar as briquettes presents an energy-efficient solution generated by these residues. In order to increase its efficiency compared to the commercial ones, the study of briquetting with different combinations of biochar, binders, pressure and temperature will be carried out. This is followed by analyzes of the immediate composition (moisture content, volatiles and fixed carbon) as well as the power superior calorific value (PCS). Through this study, we want to obtain results that enable the use of residues from the Ouricuri endocarp for the production of biochar briquettes, proving their energy efficiency at low cost. Through this research, the knowledge acquired throughout the disciplines of unitary operations will be put into practice; reactor calculations; transport phenomena, thermodynamics; organic chemistry; as well as qualitative and quantitative chemical analysis techniques.
