摘要
用动态法研究混合二乙苯在ＫＹ分子筛上的吸附，测定了在１７７℃、０．８１ＭＰａ条件下的相对选择性及吸附量，所得相对选择性ＫＡ／Ｂ＝２．６４，吸附量为０．２０５ｇ／ｇ分子筛。采用固定床脉冲吸附分离模型，优化得各组份的吸附传质系数和吸附平衡常数。研究了液相流速、温度、原料组成对分离效果的影响，得出在１７７℃的条件下，液相流速０．８０～１．００ｍＬ／ｍｉｎ是吸附操作的适宜范围，对二乙苯的传质系数较大，此时有利于二乙苯的分离。
The adsorption of diethylbenzene on KY zeolite has been studied by dynamic method The relative selectivity and adsorption capacity have been determined at 177℃ and 0 81MPa;K A/B is 2 64 Mathematical model of response curves for pulse input have been established The program for identifying mass transfer coefficient and equilibrium constant were developed The influence of liquid flow velocity,temperature and concentration of feed has been studied
