Abstract: The nickel distribution of residue feedstock and products obtained from fixed bed reactor were studied and focused on the effect of reaction temperature and various hydrotreating catalysts. Results showed that the nickel content of residue feedstock was reduced significantly after hydrotreatment; the nickel compounds were mainly removed by the guard catalyst and de-metallization catalyst. During the processes of HDS and HDN nickel removal was relatively less. Nickel removal was accelerated by the increase of treatment temperature in all the four process stages.

Key words: temperature, nickel, petroleum residue, hydrofining, hydrotreating catalyst
