Abstract

A process and an apparatus in the separation of solid catalyst particles suspended in liquid are described. After passage of a reaction chamber, the liquid is caused to pass through one or more filters retaining the suspended catalyst particles in the reaction chamber. The filter is periodically cleaned from deposits by backwashing which is carried out by means of a liquid under a pressure which is higher than the pressure in the reaction chamber in which the filter or filters are placed and which, at the start of a backwashing run, is under the action of or in itself contains a stored amount of energy sufficient to start and maintain a liquid flow through the filter or filters during backwashing. The apparatus comprises a reaction chamber in which the solid catalyst particles are suspended in liquid. One or more filters for retaining catalyst particles are disposed in the outlet conduit from the reaction chamber. Connected to said outlet conduit is a pressure container for supplying backwashing liquid for the filter or filters. The invention provides a long-time operation at effective specific amount of filtrate more than 0.5 m3 per hour and m2 of filter surface,. even when the catalyst concentration is more than 5 g per litre of liquid and when the deposit on the filter has a low permeability.
