A process for producing oxygenated products from an olefin-rich feedstock comprises reacting, in a hydroformylation stage, a Fischer-Tropsch derived olefinic product with carbon monoxide and hydrogen in the presence of a catalytically effective quantity of a hydroformylation catalyst and under hydroformylation reaction conditions, to produce oxygenated products comprising aldehydes and/or alcohols. The Fischer-Tropsch derived olefinic product is that obtained by subjecting a synthesis gas comprising carbon monoxide (CO) and hydrogen (H2) to Fischer-Tropsch reaction conditions in the presence of an iron-based, a cobalt-based or an iron/cobalt-based Fischer- Tropsch catalyst.

Un procédé de production de produits oxygénés à partir d'une charge de départ riche en oléfine consiste à faire réagir, dans un étage d'hydroformylation, un produit oléfinique dérivé de Fischer-Tropsch avec du monoxyde de carbone et de l'hydrogène en présence d'une quantité catalytique efficace d'un catalyseur d'hydroformylation, et dans des conditions de réaction d'hydroformylation, afin de produire des produits oxygénés comprenant des aldéhydes et/ou des alcools. On obtient le produit oléfinique dérivé de Fischer-Tropsch en soumettant un gaz de synthèse comprenant du monoxyde de carbone (CO) et de l'hydrogène (H¿2?) à des conditions de réaction de Fischer-Tropsch, en présence d'un catalyseur de Fischer-Tropsch à base de fer, à base de cobalt ou à base de fer/cobalt.
