Abstract: The effective thermal conductivity coefficient of stagnant fixed bed packed with cobalt-based catalyst is measured using the steady state method in the temperature range of 165~265℃ at normal pressure. The correlation of the stagnant effective thermal conductivity coefficient with the thermal conductivity of fluid and catalyst is obtained based on the steady-state theory. The maximum deviation and standard deviation of the experimental results from the correlated equation are 1.74% and 0.43%, respectively. And the stagnant effective thermal conductivity coefficients from experiments are also compared with the predicted values. They are in good agreement.

摘要： 在165~265℃及常压条件下，采用稳态法测定了气体处于静态时活性组分呈蛋壳型分布的钴基催化剂固定床的有效导热系数，并根据稳态法理论，拟合实验数据获得了固定床有效导热系数与气体导热系数和催化剂导热系数之间的关联式. 实验数据与拟合结果的最大偏差和标准偏差的绝对值分别为1.74%和0.43%. 将实验数据与前人的相关预测模型计算值进行了比较，结果表明，二者吻合良好. 利用气体处于静态时固定床的有效导热系数、Re和Pr，获得了气体流动时固定床径向有效导热系数的计算式.
