Attrition of Dolomitic Lime in a Fluidized-Bed at High Temperature

Popis výsledku v původním jazyce

The results of an experimental study on the rate of attrition of quicklime catalyst/sorbent in a high-temperature, spouted fluidized bed with quartz sand are presented. Batchwise measurements were conducted at 850oC in an electrically heated gasificationreactor of an inner diameter of 5.1 cm with two sizes (605 and 980 ?m) of high-grade, dolomitic limestone calcine (quicklime, lime). In addition to the influence of the particle size, the effect of operating (elapsed) time was investigated at several superficial gas velocities. Assuming that the attrition rate decays exponentially with time, a simple mechanistic model is presented which makes it possible to correlate the measured experimental data. The course of the attrition of lime particles is described as a function of the elapsed time and the excess gas velocity for the respective particle sizes.
