A process for introducing a solid catalyst particle feed into a fluidised or agitated vessel utilising a feed delivery device, a vertical feed dilution pipe and a feed injection pipe connected to the vessel, the process including the steps of: (a) introducing the solid catalyst particles feed from the feed delivery device into the vertical feed dilution pipe, (b) diluting the solid catalyst particles feed by letting the solid particle reaching by gravity their terminal velocity in the feed dilution pipe, (c) introducing the diluted solid catalyst particles feed into the injection pipe and mixing it with conveying gas, and introducing the gas conveyed diluted solid catalyst particles feed into the vessel.
