ABSTRACT:
The present invention relates to 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carrying out such process, by passing said oil through one or more catalyst beds within a reactor wherein catalyst is withdrawn from the bottom of the reactor and fresh catalyst is supplied to the top thereof, said catalyst being withdrawn through a discharge funnel contained in the bottom of said reactor, which funnel allows for separation of product from the catalyst via a first main screen located in the funnel upstream of the exit end of said funnel, the withdrawal of product being effected via a product outlet, in which process use is made of a second screen forming part of the discharge funnel system, located between the main screen of the funnel and the product outlet and having a larger mesh size.
