(57) [Summary]nThe present invention relates to C 9 The process for the production of alcohols comprises the following steps: a) C containing butene and butane 4 Supplying a hydrocarbon stream, b) C 4 Contacting the hydrocarbon stream with an olefin oligomerization catalyst to oligomerize and separating the resulting reaction mixture, whereby the octene-containing stream and the butene-reduced C 4 A hydrocarbon stream is obtained and c) butene is reduced 4 Steam reforming or partial oxidation of the hydrocarbon stream, thereby producing carbon monoxide and hydrogen, d) hydroformylating the stream containing octene using carbon monoxide and hydrogen in the presence of a hydroformylation catalyst 9 The aldehyde is formed, the carbon monoxide used in this case and / or the hydrogen used is at least partly derived from step c) and e) C 9 Catalytic hydrogenation of the aldehyde with hydrogen. In one variation of this method, C 4 Hydroformylation of a portion of the butenes in the hydrocarbon stream to form C 5 Forming an aldehyde, which is subsequently subjected to aldol condensation, hydrogenating the aldol condensation product, 10 -To form alcohol. This method is used C 4 -Allow full utilization of the substances of the hydrocarbon stream; |
