以减压渣油为原料，在 STRONG 沸腾床渣油加氢装置上进行了试验，考察了催化剂活性变化的规律，根据催化剂失活的3个阶段，建立了催化剂失活模型并进行了模型验证。结果表明：运行初期反应温度对催化剂失活具有明显的加速作用，运行中期催化剂的活性主要取决于催化剂的金属沉积量；建立的模型预测值与实验值吻合得较好，表明该模型具有较好的准确性，可反映沸腾床渣油加氢催化剂失活的规律。

The catalyst deactivation during the HDM process can be divided into 3 stages. Based on the operation data of vacuum residue hydrogenation in STRONG ebullated bed,a catalyst deactivation kinetic model was established and then verified. The results show that in the initial stage,the reaction temperature accelerates catalyst deactivation and in the mid-term operation the activity of catalyst mainly depends on metal deposition. The verification test proves that the model fits well with the experiment data,indicating the good reliability and accuracy of the model for residue HDM catalyst deactivation in ebullated bed.
