Abstract
The aim of this study was to evaluate the effect of impregnation with zinc chloride on the characteristics of orange albedo biochar produced in a top-lit updraft biomass conversion reactor with retort heating. The study was done in a bid to improve the porosity and surface area of the orange albedo biochar. The impregnated biochar was impregnated with zinc chloride salt (impregnation ratio = 1:1 for 24 h) before carbonization. Three techniques of characterization (SEM-EDS, FTIR, and BET) were used to characterize the biochars to determine their porosity, chemical composition, morphology, and chemistry. The un-impregnated biochar and the impregnated biochar have a specific surface area of 114.036 m2/g and 148.030 m2/g, respectively, and both biochars are mesoporous.
