Torrefaction is mild thermo-chemical process similar to pyrolysis, that can be applied to biomass to improve energy density and hydrophobicity. Comparison was made between original and torrefied forms of hazelnut shell agricultural waste biomass, when these materials were subjected to gasification using a “bench-scale” fluidised bed gasifier. Results indicated that a simplified torrefaction process was successful in physical transformation of the hazelnut shell and that the resultant syn-gas was of a relatively higher calorific value, together with lower tar content. Keywords: biomass, TGA, thermogravimetry, thermogravimetic analysis, gasification, fluidisation
