Method and device for descending catalytic cracking by injecting

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the catalyst particles but large enough to permit passage of the hydrogen-charge mixture, the reaction effluent being withdrawn from the top of the column. The reactor column is provided with means between the hydrogen-charge mixture introducing means and the catalyst bed supporting grid for mixing and dispersing the combined liquid-gas charge.

The hydrotreatment of hydrocarbons in the liquid phase is effected in a column containing a catalyst fixed or moving bed supported by a grid, wherethrough passes an ascending stream of the charge admixed with hydrogen. The perforations of the grid are small enough to prevent passage of the catalyst particles but large enough for giving passage to the hydrogen-charge mixture. The reaction effluent is withdrawn from the top of the column.
