  • Patent number: 5409877
    Abstract: A catalyst for hydroformylation of an olefin with H.sub.2 and CO is disclosed which includes an inorganic oxide carrier, and two or more catalytic metal components supported on the carrier, the metals of said catalytic metal components being cobalt and at least one auxiliary metal selected from rhodium, ruthenium, rhenium, iridium, platinum, palladium, copper, osmium and gold. By contacting a feed of an olefin, H.sub.2 and CO with the catalyst, the olefin is converted into an aldehyde and an alcohol.
