ABSTRACT Apparatus for the catalytic treatment of hydrocarbons, in particular the catalytic desulphurization and demetallisation of petroleum residues, consisting of a reactor which contains supporting means for one or more catalyst beds in the shape of a conical surface of a truncated cone, which supporting means are permeable to liquid and gas and impermeable to catalyst particles and which supporting means are attached to the wall of the reactor and have at least one downward-directed opening which is permeable to catalyst particles, in which reactor under each supporting means a tray is located which is permeable to liquid, gas and catalyst particles, which tray has one or more openings being in open communication with the above-mentioned opening(s) in the supporting means, the im- permeability of the supporting means to catalyst particles being obtained by means of filter units attached on, in or to the supporting means and the access of the catalyst particles to the underside of the said tray(s), with the exception of the said open- ing(s) therein, being prevented by means of filter units arranged under the tray(s), the latter filter units being so designed that they have the same or coarser filtering effect than the former filter units.
