催化剂性能对渣油加氢处理催化剂杂质沉积分布的影响

催化剂性能会改变催化剂运转过程中杂质的沉积分布规律。通过对催化剂物化性质的调整，可有效改善催化剂上杂质的分布，提高床层金属容纳能力、减少积炭，延长装置运转周期。通过对工业运转后的渣油加氢催化剂进行分析发现，中国石油化工股份有限公司石油化工科学研究院开发的新一代高效渣油加氢处理RHT系列催化剂在物化性质方面的改善使其性能明显优于第一代RHT催化剂，具有高脱金属活性、高容金属能力和减少催化剂表面积炭的能力，有利于发挥催化剂整体优势和延长运转周期。

Effect of catalyst properties on the deposition and distribution of impurities in residue hydrotreating process

The deposition-distribution status of the impurities is greatly affected by the properties of the catalyst during the on-stream period.Therefore,by modifying the catalyst properties,the distribution of the impurities on the catalyst can be effectively improved,the metal-storage capacity of the catalyst bed and the running cycle of the unit are enhanced,and the deposited carbon species is reduced.By systematically analyzing the running catalysts for residue hydrotreating,it was found that the new generation of RHT series catalysts developed by Research Institute of Petroleum Processing of Sinopec exhibited much better hydrodemetalization activity,metal-storage capacity and resistance to carbon deposition than the first generation RHT catalysts,and facilitated themselves to play the overall advantages and prolonged the running cycle.
