ABSTRACT:
A method is provided for removing catalyst from a distillation column reactor and replacing the catalyst with fresh or regenerated catalyst. More specifically a small particulate catalyst is supported by wire mesh or screen or filter medium on trays in a conventional distillation column and substantially submerged by the liquid on the trays. The vapor rising through the liquid tends to keep the catalyst in suspension in the liquid. A draw-off is provided for each tray having catalyst supported thereon whereby liquid containing the suspended or slurried catalyst can be removed to a separator during operation. The catalyst is separated, as in a settling tank separator, from the liquid recycled to the tray until all the catalyst has been removed. The separated catalyst is removed for either regeneration or discarding. Fresh catalyst can then be added to the separator where it is slurried into the liquid again being recirculated from the tray. The trays can all be connected to the same separator/slurry mixer by the appropriate piping and manifolds.
