Abstract
Active catalysts are prepared by (1) impregnating a carrier with a solution of a complex of an active composition or precursor thereof wherein the viscosity of the solution is not decreased upon heating or evaporation of the solvent, (2) removing the solvent and (3) decomposing the complex.
Claims15
A process for preparing a carrier for loading with a catalytically active composition or with a precusor of a catalytically active composition, which process comprises (1) impregnating a carrier having a surface area less than about 20 m.sup.2 /g with a solution of a complex of tin or iron and citric acid, formic acid, lactic acid or ethylenediamine tetraacetic acid in a solvent, the viscosity of which solution is not decreased upon heating or evaporation of the solvent, (2) subsequently removing the solvent, and (3) decomposing the complex, thereby providing a uniform distribution of the decomposed complex over the interior and exterior surfaces of the carrier.
