Speciation and distribution of alkali, alkali earth metals and major ash forming elements during gasification of fuel cane bagasse

► Preliminary model developed of distribution of ash forming elements in gasification. ► Thirty percentage of K is captured by aluminosilicates and retained in the ash. ► Seventy percentage of each of the major ash forming elements remains hard bound in the ash. ► Fifty percentage of alkali earth metals is released to the syngas. ► Clinkers and agglomerates produced were formed from K/Al/Si/Ca eutectic systems.
