摘要
本文在缩芯模型的基础上,对硫化反应作了适宜简化假设,以反应速率的计算值与实验值之差的平方和为目标函数,采用powell法回归出适宜的缩芯模型参数.试验发现在高空速下,原粒度钴钼催化剂的硫化过程服从粒径不变的缩芯模型.在H_2气充分过量的情况下关于H_2S为一级反应.回归出的活化能与温度的关系服从阿仓尼乌斯定律.
Based on the Shrinking Core model some appropriate simplified hypothesis have been made for the sulphuration reaction. By means of the Powell method and taking the sum of the square of the difference between the calculated and measured data as the objective function, we obtain appropriate parameters of the model. It has been found that the industrious pellet catalyst is sulphrated following the Shrinking Core model at large space velocity. The order of sulphuration reaction for H_2S is one under the condition in excess amount of H_2. The relation between activation energy obtained and temperature follows the Arrhenius Law.
