Abstract

A reactor system is provided which is particularly suitable for hydroprocessing a heavy hydrocarbon under catalytic slurry hydroprocessing conditions. This reactor system includes a single reaction zone containing at least one filter element for the separation of liquid product from catalyst particles in the reaction zone. Means are provided for backwashing the filter element. Preferably, at least two filter elements are provided one of which is used for separation of product and the other for introduction of hydrogen into the reactor. Additionally, means are provided for switching the flow between the two filter elements thereby permitting continuous operation of the system.
