Abstract
Abstract Process for manufacturing a catalyst suitable for the hydrogenation and reforming reactions, comprising impregnating, at a temperature of a least 160 DEG C, a solid carrier, with a homogeneous catalyst solution obtained by admixing in a solvent, at a temperature above 100 DEG 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
110 words
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°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°C.
Claim 2
Dependent Claim
