摘　　要：以壁冷式固定床测定了4种相同材质不同几何形状的负载型催化剂的传热参数。建立了二维拟均相模型,并以正交配置法对催化剂床层的径向有效导热系数和壁给热系数进行了求解。比较了催化剂几何形状的不同对于床层传热参数的影响。The heat transfer coefficients of 4 kinds of catalysts, which are of same stuff and different shape, were measured by using a cooledwall fixed bed. A twodimensional pseudohomogeneous phase model is adapted to describe the heat transfer progress in fixed bed. The effective thermal conductivity and the wall individual heat transfer coefficient are gained by using orthogonal collocation method to solve mathematical model. The effects of different shape of catalysts on the heat transfer coefficient of fixed bed are compared.
