The present invention relates to a method for producing mixtures of hydrocarbons and aromatic compounds, for use as fuel components (preferably in the range C5-C16), by means of catalytic conversion of the oxygenated organic compounds contained in aqueous fractions derived from biomass treatments, wherein said method can comprise at least the following steps: (i) bringing the aqueous mixture containing the oxygenated organic compounds derived from biomass in contact with a catalyst comprising at least Sn and Nb, Sn and Ti, and combinations of Sn, Ti and Nb; (ii) reacting the mixture with the catalyst in a catalytic reactor at temperatures between 100 and 350&#xb0; C. and under pressures from 1 to 80 bar in the absence of hydrogen; and (iii) recovering the products obtained by means of the liquid/liquid separation of the aqueous and organic phases.

Catalytic method for the production of hydrocarbons and aromatic compounds from oxygenated compounds contained in aqueous mixtures

The present invention relates to a method for producing mixtures of hydrocarbons and aromatic compounds for subsequent use as fuel components (preferably in the C5-C16 range) by catalytic conversion of the oxygenated compounds contained in aqueous fractions derived from primary biomass treatments, which can comprise at least the following steps: (i) bringing the aqueous mixture containing the oxygenated compounds derived from biomass in contact with a catalyst comprising at least W and/or Nb, and combinations of Nb and W with other elements, (ii) reacting the mixture with the catalyst in a catalytic reactor at temperatures between 50&#xb0; C. and 450&#xb0; C. and under pressures of 1 to 120 bar; and (iii) recovering the products obtained by a liquid/liquid separation process of the aqueous and organic phases.
