A continuous process for the catalytic treatment of a hydrocarbon oil and an apparatus for carrying out such process, by passing said oil through one or more catalyst beds (10, 25) within a reactor (1) wherein catalyst is withdrawn from the bottom of the reactor (1) and fresh catalyst is supplied via the top thereof, said catalyst being withdrawn through a discharge funnel (26) contained in the bottom of said reactor (1), which funnel (26) allows for separation of product from the catalyst via a screen (16) located in the funnel (26) upstream of the exit end (7) of said funnel (26), the withdrawal of product being effected via a product outlet (6), in which process use is made of a further screen (17) forming part of the discharge funnel system, located between the main screen (16) of the funnel (26) and the product outlet (6) and having a larger mesh size. |
