Comparison of Procedures for Immediate Chemical Analysis of Charcoal

Abstract: -The climate change, the quest for sustainability and the strong environmental pressures for alternatives to traditional fossil fuels have increased the interest in the search and use of renewable energy sources. Among them stands out the biomass of charcoal coming from renewable forests, widely used as a thermal reductant in the steel industry in the detriment of the use of mineral coal coke. This study aimed to compare different operating procedures of immediate chemical analysis of charcoal. Seven essays to… Show more

“…Os cálculos para a determinação desses parâmetros, em %, se basearam nas seguintes expressões: MV=100[(P1-P2)/P], TC=100[(P2-P0)/P] e CF=100-MV-TC, em que P é a massa original da amostra, em g; P0 é a massa original do cadinho, em g; P1 é a massa inicial do cadinho + a massa da amostra, em g; P2 é a massa final do cadinho + a massa da amostra, em g (Lana et al, 2016).…”
