Attrition of zinc-titanate sorbent particles were measured in a fluidized bed at a condition that attrition by gas jets of a distributor was dominant. Abrasion was found to govern the attrition of present sorbent particles. The top size of particles produced by attrition and the attrition rate increased with an increase of static bed height when the static bed height was less than jet penetration length of the distributor. However, the top size of produced particles and the attrition rate decreased with increasing static bed height when the static bed height was greater than jet penetration length of the distributor. Maximum values of the top size of produced particles and the attrition rate were found at a static bed height corresponding to a jet penetration length of the distributor. The top size of produced particles and the attrition rate increased with increasing relative humidity or gas velocity, whereas with decreasing temperature.
