Comprehension of alkali behavior in biomass gasification is essential because it can impact process (corrosion, agglomeration …). Several workers have used thermodynamic calculations and observed that some biomasses volatilised more HCl than others. However, none of them has explained explicitly and checked it experimentally until now. Hence, the aim of this paper is to study the alkali volatilisation of various biomasses representative of the feedstock diversity during steam gasification both through thermodynamic calculations and gasification...
