Influences of Pectin on the Water Resistance Index of Orange Waste Charcoal Briquettes

Abstract

Brazil's significant agriculture makes it capable of taking advantage of its residues in the thermochemical conversion process, such as carbonizing orange solid waste in order to obtain fuel briquettes. The charcoal must undergo an energy densification process, and a binder is required on this stage. The aim of this study was to verify the influence of the binder pectin on orange bagasse charcoal briquette's water resistance. The results showed that pectin improved the briquettes water resistance, however the WRI of all the samples were still considered low, once the best briquette WRI obtained was 67% when 15% of pectin was applied.
