影响S Zorb装置汽油辛烷值损失因素分析

ANALYSIS OF FACTORS AFFECTING OCTANE NUMBER LOSS OF GASOLINE IN S ZORB UNIT

根据齐鲁分公司原90万t/aS Zorb催化汽油吸附脱硫装置首次开工以来不同工况下辛烷值损失变化情况,分析影响汽油辛烷值损失的因素,包括原料、反应条件、吸附剂性质的影响及循环氢纯度的影响等。结合装置运行现状,提出进一步降低精制汽油辛烷值损失的措施。

According to the change of octane number loss of gasoline in the 900kt/a S Zorb unit at SINOPEC Qilu Company under different operating conditions since its first start-up,the factors affecting the octane number loss of gasoline are analyzed,including the influences of raw materials,reaction conditions,adsorbent properties and recycling hydrogen purity.Combining with the operation status of the unit,some measures are put forward for further reducing the octane number loss of refined gasoline.
