Abstract
A process and hydrodeoxygenation catalyst for producing high-quality diesel and naphtha fuels from a feedstock that contains oxygen containing components derived from renewable organic material in which the hydrodeoxygenation catalyst is a supported Mo catalyst and in which the support has a bimodal porous structure. The hydrodeoxygenation catalyst has a Mo content of 0.1 to 20 wt %. The support is alumina, silica, titania or combinations thereof, and the support has a bimodal porous structure with pores with a diameter larger than 50 nm that constitute at least 2 vol % of the total pore volume.

Process for production of a hydrocarbon fuel from renewable organic material of biological origin comprising the steps:
- (a) forming a feedstock by combining a fossil hydrocarbon fuel with a renewable organic material wherein the content of renewable organic material material is 1 to 35 vol %;
- and
- (b) mixing the feedstock of step (a) with a hydrogen-rich gas and conducting the combined stream to a hydrodeoxygenation stage by contacting said combined stream with a hydrodeoxygenation catalyst,
- wherein the hydrodeoxygenation catalyst is a supported unpromoted Mo catalyst having Mo content of 0.1 to 20 wt %, the support being selected from alumina, silica, titania and combinations thereof, and said support having a bimodal porous structure with pores with a diameter larger than 50 nm that constitute at least 2 vol % of the total pore volume.
A hydrodeoxygenation catalyst in the form of a supported unpromoted Mo catalyst having Mo content of 0.1 to 20 wt %, the support being selected from alumina, silica, titania, and combinations thereof, and said support having a bimodal porous structure with pores with a diameter larger than 50 nm that constitute at least 2 vol % of the total pore volume, for the treatment of feedstocks combining a fossil hydrocarbon fuel with a renewable organic material wherein the content of renewable organic material material is 1 to 35 vol %.
