CONCLUSIONSBioenergy III: Present and New Perspectives on Biorefineries – Lanzarote, May 2011• Char and ash from MBM can retain H2S from a synthetic gas mixture.• Apart from its composition, BET surface of the char can help to Ca availabilityfor its reaction with H2SCONCLUSIONS4. Conclusions• Ash obtained from the solid residue produced in the MBM pyrolysis could bea substitute of the dolomite used as sulfur removal in gas cleaning gasificationprocesses.Bioenergy III: Present and New Perspectives on Biorefineries – Lanzarote, May 2011STUDY OF THE DESULPHURATION POWER OF THE CHAR FROM MEAT AND BONE MEAL PYROLYSISE.
