Patent ID: 7579382

Claim:
A process for the charging of a catalyst into a slurry bubble column reactor in activation phase which comprises: a) incorporating the catalyst, previously reduced, in a matrix of paraffinic waxes, solid at room temperature; b) melting and collecting the paraffinic matrix in a charging vessel, maintained at a high temperature, together with a diluent which is miscible with the molten paraffinic matrix and which is in liquid form both under the conditions present in the vessel and at room temperature, a stream of a first inert gas being distributed in said charging vessel from the bottom so as to obtain a sufficiently homogeneous suspension; c) pressurizing the charging vessel in which the complete melting of the paraffinic matrix has been effected at a pressure higher than that of the reactor maintaining the system fluidized by the continuous introduction of said first inert gas from the bottom of said vessel; d) transferring, due to the pressure change, a diluted solution from the charging vessel under pressure to the reactor, initially empty, maintained at a temperature higher than or equal to that present in the charging vessel flushed in turn from the bottom with a second inert gas ( 5 ); e) repeating steps (b) to (d) until a suspension level is reached in the reactor which is sufficient for aligning optional external equipment envisaged for the treatment of the suspension; f) repeating steps (b) to (d) until the normal operating suspension level is reached in the reactor and in the optional external equipment envisaged for the treatment of the suspension; g) feeding a synthesis gas diluted with said second inert gas to the base of the reactor.
