CANADIAN PATENT APPLICATION OF BENGT GUSTAF FRANZ?N FOR PROCESS IN THE SEPARATION OF CATALYST PARTICLES SUSPENDED IN LIQUID A process in the separation of solid catalyst particles suspended in liquid is 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 with an amount of liquid greater than the amount of liquid that can be enclosed in the filter or filters. The specific backwashing flow through the filter or filters is so adapted that it will be greater than the specific filtrate flow through the filter or filters during the first 20 seconds after backwashing. |
