摘要
Abstract
The effects of rotary kiln inclination height at both high and low rotating rates on the residence time of catalyst are studied.The catalyst residence time distribution function and parameters value with different speed and slope height are obtained by simulating experimental data using the function of Sigmoid (C).The results indicate that the average residence time of catalyst in the rotary kiln decreases linearly with the increase of inclination height at both high and low rotating rates.The average residence time decreases faster at high rotating rate then slower at a low rotating rate.At different inclination heights,the average residence time of catalyst is inversely proportional to the rotating rate.The distribution density of residence time becomes more concentrated as the rotate speed and the inclination height increase,and the converse is also true.关键词
