Cynara cardunculus L. was gasified in a pilot-scale BFB using magnesite and olivine at different temperatures.
Tar analysis based on total GC detectable, secondary and tertiary tars as well as individual tar compounds was discussed.
Relatively high hydrogen content due to magnesite, olivine and biomass ash composition was obtained.
Magnesite leaded to a better gasification performance at low temperature while olivine did at high temperature.
No agglomeration problems were found due to the addition of kaolin to the raw biomass.
