METHOD TO PRODUCE FUEL HYDROCARBONS FROM RENEWABLE FEEDSTOCKS Russian patent published in 2013 - IPC C07B37/06 C07C1/20 C07C9/14 C07C9/22 C07C11/00 C10G3/00 C10L1/06 

FIELD: explosives.

SUBSTANCE: invention relates to the method for selective production of hydrocarbons suitable for use as diesel fuel, consisting in decarbonylation / decarboxylation of a mixture of carbonic acids C₈-C₂₄ (saturated and non-saturated) in a dissolvent in hydrogen atmosphere in presence of a heterogeneous catalyst representing palladium on aluminium oxide at the temperature of 200-400°C and pressure of 0.1-5 MPa. The method is characterised by the fact that a granulated catalyst is used, in which palladium is distributed in the surface layer of the carried with penetration depth of 0.1-0.6 mm and palladium content in the catalyst making 0.25-5 wt %.

EFFECT: invention provides an efficient industrial method for selective production of hydrocarbons from renewable sources using highly efficient catalysts of fatty acids deoxygenation to saturated hydrocarbons suitable for use as components of diesel fuel.
