Claim 0:
1. A procedure for the preparation of a catalyst, comprising:
1) mixing a mineral acid and ammonium salts, and shaking the mixture at a temperature of 25° C. until a clear solution is obtained, with a pH variation between 1 and 2;
2) incorporating Nickel salts into the clear solution and solubilizing at 40-100° C., then dissolving in water, and maintaining agitation of the solution for a time of 3 h at a temperature of 25° C., resulting in a green and translucent solution;
3) storing the green and translucent solution in a closed container under ambient conditions; and
4) dehydrating the catalyst at 90° C., wherein the catalyst has a final molar ratio of 1.0 Ni, 0.084 Mo, 0.295 H+, 14.42 H2O, at pH 1 to 3;
and wherein the catalyst transforms heavy and extra-heavy crude oils into lighter oils.
