摘要: The higher alcohol yield of a hydroformylation process including hydroformylation, catalyst removal, hydrogenation and higher alcohol separation stages is improved by subjecting the Heavy Oxo Fraction (HOF) obtained following higher alcohol separation to steam cracking in the presence of a catalyst system comprising a dehydration-catalytic metal on an acidic support. The resultant cracked HOF mixture comprising a major proportion of olefin and saturated hydrocarbon is recycled to the hydroformylation stage.
