Abstract
Process for manufacturing a catalyst suitable for the hydrogenation and reforming reactions, comprising impregnating, at a temperature of a least 160.degree. C, a solid carrier, with a homogeneous catalyst solution obtained by admixing in a solvent, at a temperature above 100.degree.C, a salt of a metal whose atomic number is in the range of from 22 to 29, 40 to 47, 72 to 79 and 90 to 92, with a metallic or organo-metallic reducing agent, the metal component being selected from groups Ia, IIa, IIb and IIIb.
Claims7
In a process for manufacturing a catalyst comprising the following steps:
- a. preparation of a homogeneous catalyst solution by admixing, at a temperature higher than 100.degree.C, in a solvent, a compound of a metal (A) selected from the group consisting of those having atomic numbers of 22 to 28, 40 to 46, and 72 to 78 with a metallic or organometallic reducing agent, the metal (B) of the reducing agent being selected from the group consisting of metals of groups Ia, IIa, IIb, and IIIb;
- and
- b. impregnation of a solid carrier with said solution, wherein the improvement comprises conducting said impregnation at a temperature of at least about 160.degree.C.
