Parâmetros físico-químicos do carvão vegetal: uma revisão bibliográfica

Abstract

Charcoal is widely used due to its energetic and structural characteristics, being considered an important product derived from forest biomass. The quality of this material is directly related to its physicochemical properties, which influence its behavior, performance, and potential applications. In this context, the present study aimed to carry out a bibliographic review of the main physicochemical parameters of charcoal, highlighting the properties most commonly used in quality assessment. The main physical properties addressed included density, porosity, surface area, mechanical strength, and friability, while the chemical properties comprised fixed carbon content, volatile matter content, ash content, and calorific value. The literature analysis showed that these parameters are important indicators of charcoal quality, as they directly influence its structural and energetic characteristics. Higher fixed carbon contents and lower ash contents are generally associated with better energetic performance, whereas physical properties contribute to the stability and integrity of the material during handling and use. It is concluded that physicochemical characterization is essential for evaluating the quality of charcoal, allowing a better understanding of the factors that influenceits performance and utilization characteristics.
