PROCESS AND APPARATUS FOR THE HYDROCONVERSION OF HYDROCARBONS

摘要

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 The reaction effluent is withdrawn from the top of the column.
