苯系物在活性炭上吸附过程的研究

Adsorption Processes of Benzene, Toluene and m-xylol from Air by Activated Carbon

以苯、甲苯和间二甲苯二组分及三组分混合物为吸附质,研究了在不同流速和不同柱高下在活性炭固定床上的等温吸附过程.对建立的模型采用正交配点法和四阶龙格-库塔法求解.结果表明,正交配点法具有上机前处理量少、计算量少的优点,计算结果与实验值吻合良好.

In this paper the isothermal adsorption processes of binary and ternary mixtures of benzene, toluene and m-xylol are investigated in a fixed bed of activated carbon of different column heights and under various flow velocities. The model established is solved by the orthogonal collocation method and the fourth order Runge-Kutta method. The results show that the orthogonal collocation method has the advantages of less handling before computation and shorter computing time. A good agreement between the computation results and the experimental results is obtained.
