Effective Factors in Preventing Green Oil Formation in Chloride Adsorbents, M.Sc. Thesis Sharif University of Technology ; Farhadi, Fathollah (Supervisor)
Abstract
In order to prevent the CCR catalysts from sintering and maintaining their acidity, some chloride compounds are added to these catalysts during regeneration process. The existence of these compounds in downstreams units and equipment causes problems such as corrosion, fouling, etc. Therefor for eliminating these chloride compounds from the exit stream a chloride adsorbent is used. The common compound that is suggested for this application is activated alumina for its high surface area. When Olefin or Aromatics exist in the stream, that is common in many units, a side reaction happens and green oil is formed. In this study, different factors in green oil formation has been studied. Although...
