The invention relates to a method for extracting hydrocarbon mixtures that have an increased proportion of hydrocarbons of a medium chain length (8 to 16 carbon atoms), or the corresponding pure compounds. Firstly, a starting material is provided that includes at least 50 wt. % unsaturated hydrocarbon compounds having oxygen. The compounds include olefin fragments of the formula —C.sub.1C.sub.xH.sub.2x—CH═CH—C.sub.yH2.sub.y+1 with at least 14 carbon atoms, carbon atom (C.sub.1) being saturated with substituted or unsubstituted heteroatoms and/or hydrogen. In a conversion reactor, this starting material is brought into contact with a porous catalyst based on carbon, in the absence of oxygen, and at a temperature of between 200 and 800° C.; and a product mixture that contains hydrocarbons is produced containing an increased proportion of hydrocarbons with medium chain lengths. Finally, the product mixture including hydrocarbons is collected and fed to a separating device in which a product separation is carried out.
