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
