超深度加氢脱硫体相法催化剂在反应器内装填位置研究

摘要

The combination use of the bulk catalyst developed by SINOPEC Fushun Research Institute of Petroleum & Petrochemicals(FRIPP)and conventional diesel hydrotreating catalyst increases the HDS activity.The effect of loading positions of the bulk catalyst on HDS was tested.The results show that the bulk catalyst loaded at the upper part in the reactor(lower reaction temperature zone)is helpful to removal sulfur for diesel feeds with low processing difficulty;while for diesel with medium/higher processing difficulty,the lower part of the reactor(high temperature reaction zone)is better for bulk catalyst loading.The work provides a basis for the combination loading of bulk catalyst and conventional hydrotreating catalyst to improve the diesel ultra-deep HDS performance.%介绍了中国石化抚顺石油化工研究院研究开发的超深度加氢脱硫体相法催化剂与常规柴油加氢催化剂在反应器内不同装填位置的加氢脱硫效果.试验结果表明:对于几种典型的混合柴油,当处理加氢脱硫难度较低的原料油时,体相法加氢催化剂装填在反应器的上部(低温反应区),加氢脱硫效果较好;当处理中等或较高加氢脱硫难度的混合柴油原料时,体相法加氢催化剂装填在反应器的下部(高温反应区),加氢脱硫效果较好.这一研究结果可为炼油厂柴油加氢装置采用体相法加氢催化剂和常规加氢催化剂匹配装填技术提高柴油产品质量提供依据.
