Abstract
A process for preparing catalysts has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid. The aqueous solution of the chelating ligand and a promoter metal salt is first prepared heated to a temperature of about 80.degree. C. to about its boiling point and then combined with an aqueous solution containing a Group VIII metal compound. Next this mixed solution is aged at a temperature of about 40.degree. C. to about 100.degree. C. and then used to impregnate a support, e.g., alumina spheres. The impregnated support is then dried, calcined and reduced with hydrogen. Prior to reduction the catalyst may optionally be treated with a chlorine or chloride stream.
