Preparation and characterization of adsorbents/catalysts from forest biomass fly ash

Abstract

This paper deals with the production of materials, known as adsorbents/catalysts, from forest biomass fly ashes. The ashes were subjected to different pre-treatments to generate two kinds of precursors. Via an agglomerative process using domestic residual oils and a dry sieving method. Both precursors, after an activation process using potassium hydroxide, were characterized in terms of BET surface area. The adsorbent/catalyst obtained from the precursor subjected to dry sieving exhibited a developed porosity, which in turn gave rise to surface areas in the range of 2000m2/g.
