✦ Synopsis
Detailed chemical composition data were obtained for five atmospheric resids and products prepared in a continuous pilot plant by Unicracking/HDS, Unocal's fixed bed residual oil hydrotreating process. The results showed that the reactivities for removal of sulphur, nickel, vanadium and coke precursors cannot be predicted from simple physical or chemical properties. In particular, sulphur and metals removal reactivities are not proportional to feed sulphur or metals levels. There is a correlation of metals removal reactivities with the fraction of total feed metals found in the resin fractions. The oils studied were Heavy Arabian, Hondo (from California), Maya (from Mexico), Gach Saran (from Iran) and a blend of typical West Coast refinery feedstocks.
