摘　　要： 加氢精制（一）B装置在焦化汽油加氢精制过程中存在催化剂床层压降升高过快的问题，分析认为，造成该问题的主要原因为换热器壳程结焦现象严重、原料油内金属杂质沉积、原料油性质在中间储存过程中发生变化。通过对原料油流程的优化及对相关设备管线进行清洗和吹扫等手段，使该装置催化剂床层压降稳定在0．1MPa以下。 There is an excessive pressure drop problem at catalyst beds of unit 1-B of coker gasoline hydrotreater. It is caused by the serious coking on the shell sides of the heat exchangers, by the metal deposits coming from feed stocks and by the quality change of feed stock due to storage stability. The pressure drop of catalyst beds of the unit is now stabilized and kept below 0. 1 MPa after taking the following solutions ： the optimization of process flow, the purging of equipment and pipelines involved, and so on.
