The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. The triglyceride containing feedstock is first split to provide a mixture containing fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. The oily phase containing fatty acids is subjected to fractionation, whereby specific fractions may be refined to products with controlled hydroprocessing. Products may contain paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.

The invention relates to a method (100) for producing a target compound, wherein a paraffin is subjected to an oxidative dehydrogenation (1) with oxygen to obtain an olefin, and wherein the olefin is subjected to a hydroformylation (2) with carbon monoxide to obtain an aldehyde, wherein the paraffin and the olefin have a carbon chain having a first carbon number and the aldehyde has a carbon chain having a second carbon number which is one greater than the first carbon number. It is provided that carbon dioxide is formed as a by-product in the oxidative dehydrogenation (1), that the carbon dioxide is subjected to dry reforming (3) at least in part with methane to obtain carbon monoxide and hydrogen, and that the carbon monoxide obtained in the dry reforming (3) and/or the hydrogen obtained in the dry reforming (3) is supplied to the hydroformylation (2). A corresponding installation is also the subject matter of the invention.
