  • Process for withdrawing catalyst particles from a reaction zone
    Patent number: 4659455
    Abstract: The invention concerns a process for withdrawing catalyst, particularly from a moving bed.The device is characterized in that fins (4) (see FIG. 1A), shaped as corner-plates, are arranged, on a plate (6) which supports the catalyst bed radially around each vertical duct for catalyst withdrawal, so that the flow of catalyst particles converges towards the withdrawing ducts.The apparatus is useful for example in hydroconversion reactions, particularly in hydrotreatments of heavy oil cuts.
