Process for preforming cobaltous salts using shell-type preformer catalysts
 A process for preparing oxo alcohols and aldehydes by the cobalt catalyzed hydroformylation of C.sub.2 to C.sub.17 linear or branched monoolefins with subsequent hydrogenation of the hydroformylation product, in which oxo process aqueous solutions of cobalt salts are converted to active hydrido cobalt carbonyl species in a preformer reactor under preforming reaction conditions, the improvement characterized by the preformer reactor containing a shell-type, metal on substrate, preformer catalyst.
