Abstract

The Attrition of 300 µ m natural zeolite particles was studied in a laboratory scale Draft Tube Spouted Bed (DTSB) and Spout-Fluid Bed (DTSFB). It has been shown that the Attrition rate decreases with time and reaches to an almost constant value. The results show that the prevailing Attrition mechanism under the conditions of this work is the surface abrasion which occurs due to the collisions between particles. It has been found that increasing the cone angle from 30º to 60º in the DTSB, causes a decrease in the extent of Attrition. In addition, by increasing the spouting air velocity and the height of the entrainment zone in the DTSB, the extent of Attrition increases due to a more energetic collision between particles as well as the increased circulation rate of solids. Increasing the auxiliary air velocity in the DTSFB increases the rate of Attrition. A comparison between the Attrition in the DTSB and DTSFB has been conducted and has indicated that applying the auxiliary air flow causes up to a 6 % increase in the extent of Attrition. An empirical correlation is derived for evaluating the extent of the Attrition in the DTSB and DTSFB. This empirical correlation is in good agreement with the experimental data.
