Method and facility for producing a target compound

A method for producing a target compound, the method comprising:

• providing a starting gas mixture comprising
• a paraffin, an olefin, carbon monoxide, and carbon dioxide,
• subjecting the olefin in at least a portion of the starting gas mixture is to a hydroformylation process to obtain an aldehyde, wherein the olefin has a carbon chain having a first carbon number and the aldehyde has a second carbon chain having a second carbon number, wherein the second carbon chain is greater by one than the first carbon number, and
• removing wherein the carbon dioxide present in the starting mixture at least in part in at least one of the upstream or downstream or combinations of the upstream and downstream relative to the hydroformylation process,
• subjecting at least part of the separated carbon dioxide to a dry reforming process with methane to obtain carbon monoxide, and using at least part of the carbon monoxide obtained in the dry reforming process in the hydroformylation process.
