METHOD FOR PRODUCING HYDROCARBONS WITH MEDIUM CHAIN LENGTHS, AND THE USE OF SAME

摘要

The invention discloses 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 contains at least 50 wt.% unsaturated hydrocarbon compounds containing oxygen. These contain olefin fragments of the formula -C1CxH2x-CH=CH-CyH2y+1 with at least 14 carbon atoms, carbon atom (C1) 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 that contains hydrocarbons is collected and fed to a separating device in which a product separation is carried out.
