Process for the charging of a catalyst into a reactor suitable for reactions in heterogeneous phase

This invention relates to a process for the conditioning of a catalyst contained in a bubble column reactor suitable for reactions in heterogeneous phase, which comprises: a) regulating the temperature and pressures at values suitable for the conditioning, i.e. within the range of 200-230 0 C and 0....

Summary:This invention relates to a process for the conditioning of a catalyst contained in a bubble column reactor suitable for reactions in heterogeneous phase, which comprises: a) regulating the temperature and pressures at values suitable for the conditioning, i.e. within the range of 200-230 0 C and 0.5-1.5 MPa; b) gradually substituting the inert gas with synthesis gas, up to a concentration of inert gas ranging from 5 to 50% by volume and maintaining a partial water pressure (co-product of the Fischer-Tropsch synthesis reaction) lower than 1.0 MPa, preferably lower than 0.5 MPa; c) maintaining the conditions of point (b) for 24-72 hours; d) gradually increasing'the pressure inside the reactor up to regime values (0.5-5 MPa); e) gradually reducing the concentration of inert gas to zero until regime conditions; and f) gradually increasing the reaction temperature until regime values (200-3500 C) are reached.
