CATALYST AND PROCESS FOR HYDRODEOXYGENATION OF ORGANOOXYGEN PRODUCTS OF PROCESSING PLANT BIOMASS Russian patent published in 2012 - IPC B01J23/755 B01J23/825 B01J23/84 B01J23/85 B01J23/89 B01J21/02 B01J23/70 C07C7/148 

FIELD: chemistry.

SUBSTANCE: invention relates to developing a catalyst and a process for obtaining hydrocarbons via catalytic hydrodeoxygenation of products of processing plant biomass. The invention describes a catalyst for hydrodeoxygenation of organooxygen products of processing plant biomass, which is a complex composite containing transition metals and is a mixed oxide of the following type: where M_i is a transition metal in oxide form, other than nickel or boron, 2≤n≤5, with atomic ratio from 0.01-99, mainly from 7 to 99, and a stabilising additive in amount of not more than 30 wt %. The invention also describes a process for hydrodeoxygenation of organooxygen products of processing plant biomass, which is carried out in a single step at hydrogen pressure 0.5-20 MPa, temperature 250-320°C in the presence of the catalyst described above.

EFFECT: high activity of the disclosed non-sulphided catalysts, which enable to conduct a process for hydro-deoxygenation of oxygen-containing compounds - model compounds of products of processing plant biomass at high substrate/catalyst ratios.
