Abstract

This review considers and systematizes the results of studying the deactivation of hydrotreatment catalysts currently available in the scientific and technical literature. The effect the composition of the feedstock and the conditions of hydrotreatment have on the coking of catalysts is shown. The reasons for the morphological changes of the active component and the possibility of reducing this type of catalyst deactivation during commercial operation are considered. The effect of a pressure drop on the run time, the action of catalyst poisons, and the ways, in which they enters the hydrotreatment distillates is shown. This information could be useful and interesting to chemical engineers studying catalytic systems, and to workers of oil refining industry.

停用加氢处理催化剂：综述

摘要

本综述考虑并系统化了目前科学和技术文献中加氢处理催化剂失活研究的结果。显示了原料组成和加氢处理条件对催化剂结焦的影响。考虑了活性组分形态变化的原因以及在商业运行过程中减少此类催化剂失活的可能性。显示了压降对运行时间的影响、催化剂毒物的作用以及它们进入加氢处理馏出物的方式。这些信息可能对研究催化系统的化学工程师和炼油行业的工人有用且有趣。
