Role of surface morphology on bed material activation during indirect gasification of wood

• Olivine and feldspar exhibit similarities regarding their ash layer formation. Formation of layers is more pronounced on convex areas bed particles. A Mn Fe causes the particles to an oxygen carrying ability. Alkali alkaline earth metals are present surface alkali-feldspar were utilized in separate campaigns indirect dual fluidized gasification campaign with woody biomass as fuel. After three days, both materials reported be active towards tar removal exhibited oxygen-carrying abilities had formed consisting outer deposition inner interaction layer. X-ray microtomography analysis concluded that a preferred happens onto regions particles, which results increase thickness over regions. This effect most for product deposition. The exhibits homogeneous probably by Ca from Transmission electron microscopy revealed presence solid solution Mg. found aged therefore attributed likely contributing catalytic activity material removal.
