滴流床反应器中气液传质系数的测定

Measurement of gas-liquid phase mass transfer coefficients in trickle bed reactor

采用NaOH CO2 N2系统,在液相进行拟一级瞬时不可逆反应的化学吸收方法,研究了滴流床反应器中气液传质.实验得到了气速、液速分别对总传质系数KG液膜传质系数kL和气膜传质系数kg的影响.

The gas-liquid phase mass transfer coefficients regarding as absorption in liquid accompanied by pseudo-first order instantaneous irreversible reactions for NaoH-CO_2-N_2 system in trickle bed reactor were determined. Through experiments, the correlation of K_G, K_L, kg with gas flowrate and liquid flowrate was obtained.
