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 &#x2014;CCH&#x2014;CH&#x2550;CH&#x2014;CH2with at least 14 carbon atoms, carbon atom (C) 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&#xb0; 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.

Method for extracting hydrocarbons with medium chain lengths, and the use of the same

The invention relates to a method for catalytically condensing organic compounds containing at least one oxo and/or hydroxyl function into CH acidic compounds and/or coupling said organic compounds to the CH acidic compounds in the presence of a catalyst which comprises an active carbon substrate provided with a metal. The method is suitable in particular for generating higher alcohols, aldehydes, ketones, and/or alkanes as well as mixtures thereof.

Method for the purpose of a catalytic condensation or coupling

The invention provides a process for preparing higher alcohols and/or aldehydes and also mixtures thereof by catalytic reaction of ethanol, the reaction taking place in the presence of at least one catalyst, the catalyst comprising an activated-carbon substrate which is provided with at least one metal, and more particularly has at least one metal dope.

Catalytic conversion of alcohols and aldehydes

A process for obtaining gaseous hydrocarbons from a starting material which contains oxygen-containing hydrocarbons. The process includes providing the starting material and contacting the starting material with a porous catalyst at a temperature of 300-850&#xb0; C. in the absence of oxygen in a converting reactor so as to form a hydrocarbon-containing product gas mixture in which a proportion by weight of gaseous hydrocarbons is greater than a proportion by weight of liquid hydrocarbons in the gas mixture. Additionally, the process includes collecting a hydrocarbon-containing product gas stream of the hydrocarbon-containing product gas mixture and introducing the product gas stream into a separation apparatus in which product fractionation is carried out.

Method for extracting gaseous hydrocarbons from biogenic raw materials

The present invention relates to a method for producing fatty acid esters from fats and/or oils of biogenic origin by transesterification with monovalent or polyvalent alcohols in the presence of a special hydroxy-functional quaternary ammonium compound as the catalyst.
