Abstract

Development and application of two COR vanadium-tolerant olefin-reducing catalysts, specially developed for Refinery of Sinopec Urumqi Company and Sinopec Cangzhou Company, were described. Commercial application of the two catalysts(CORS and CORV-CZ) showed that, combining with adjustment of the process for reducing olefin, the catalysts reduced olefin volumetric fraction by 12 to 18 percentage points while tolerating 4000×10~(-6) mass fraction of vanadium in the balance catalyst and maintaining ideal octane number and product distribution.
