Process for hydrotreating heavy hydrocarbons in liquid phase in the
presence of a dispersed catalyst
摘要:
A mixture of heavy hydrocarbons, hydrogen and fresh catalyst comprising metals from the groups Vb, VIb, VIIb or VIII is passed first in a furnace for a limited heating time and then in a reactor where recycled catalyst is also added; the recycled catalyst is used in the form of a suspension recovered by fractionation of the reaction product.
