还原吸收法尾气处理装置及CT6-5催化剂工业运行回顾

Reducing Absorbing Tail Gas Treating Units had Review of Industrial Application of C T6-5 Catalyst

胜炼共有三套硫磺回收尾气处理装置，均采用还原吸收法，此中还原工序均使用CT6－5尾气加氢催化剂。本文回顾了这些装置各个工序十余年来的运行情况及实施的改进；CT6－5催化剂曾受到多种苛刻条件的冲击，仍能保持较高的活性和强度，证明它是可以满足生产要求的优良催化剂。

Shengli Refinery has totally three sets of sulfur recovery tail gas treating units, all of themare of the reducing absorbing type. Reducing processes use CT6- 5 tail gas hydrogenation catalyst.The paperreviews the units'operation history and the mprovements made. CT6 - 5 catalyst kept relatively high activityand strength,even though being impacted by severe operation conditions- The resrult shows that CT6 - 5 is agood catalyst which is able to meet the demand of industrial production.
