Abstract
Attrition characteristics of alumina catalyst for catalytic incineration have been studied in a fluidized bed cold mode combustor (F10 cm, 160 cm height). The particle size and density of alumina catalyst were 1.4-1.7 mm and 1.13 g/cm3. As operating variables, excess gas velocity (U-Umf) and bed weight (Wb) were selected. The experimental results show that attrition rate of alumina catalyst increased with excess gas velocity and bed weight due to intensive rubbing and collision caused by bubble coalescence. The size of the entrained particles collected in cyclone ranges over 0.5 to 100 mm, and the mean size for number base increases with an increase of excess gas velocity.
