DETERMINATION OF PROPERTIES OF RESIDUAL CHAR AFTER GASIFICATION OF BAGASSE

Abstract

Bagasse ranks among Vietnam's most abundant agricultural residues. The application of bagasse for energy generation via biomass gasification technology presents an innovative approach. Nevertheless, prevailing biomass gasification methodologies exhibit relatively limited efficacy and produce a substantial surplus of char following the gasification procedure. This investigation, however, focuses on acquiring and evaluating residual char produced from the gasification of bagasse within a commercial system. Proximate and ultimate analyses indicate that the char derived from bagasse gasification possesses low ash content while retaining a significant carbon fraction. SEM-EDS examination reveals that both bagasse and its chars consist of distinct thin layers with a rough and non-uniform surface. Additionally, bagasse char displays considerable porosity, as demonstrated by its specific surface area of 749 m2/g, determined using the nitrogen adsorption technique. This outcome places it in the same category as particular commercial activated carbons. The physical and chemical attributes of bagasse char post-gasification affirm its potential as an economical and eco-friendly adsorbent material.
