ABSTRACT:
The hydrotreatment of hydrocarbons in the liquid phase is effected in a column containing a catalyst bed supported by a grid, wherethrough passes an ascending stream of the charge admixed with hydrogen which expands the catalyst bed, the perforations of the grid being small enough to prevent passage of the catalyst particles but large enough to permit passage of the hydrogen-charge mixture, the reaction effluent being withdrawn from the top of the column.
