Methods and systems for converting a renewable fuel intermediate composition to finished transportation fuel are provided herein. In some examples, a renewable fuel intermediate composition is flowed over a first catalyst in a first reaction zone to generate a saturated, hydrodeoxygenated product. A liquid portion of the renewable fuel intermediate composition may be characterized as having more than about 70 wt % of the oxygen being within ketone groups. The saturated, hydrodeoxygenated product may be flowed over a second fixed-bed catalyst in a second reaction zone to generate a product including the finished transportation fuel.

The invention relates to a self-supported mixed metal sulfide (MMS) catalyst for hydrotreating hydrocarbon feedstock and to a method for preparing the catalyst. The self-supported MMS catalyst consists essentially of molybdenum sulfide and tungsten sulfide, wherein the catalyst contains at least 0.1 mol % of Mo and at least 0.1 mol % of W, on a transition metal basis.

The invention relates to a self-supported mixed metal sulfide (MMS) catalyst for hydrotreating hydrocarbon feedstock and to a method for preparing the catalyst. The self-supported MMS catalyst contains Ni:W in a mole ratio of 1:3 to 4:1, on a transition metal basis. The self supported MMS catalyst is characterized as having an HYD reaction rate constant of at least 15% higher than that of a catalyst comprising nickel sulfide alone or a catalyst comprising tungsten sulfide alone, when compared on same metal molar basis in hydrotreating of benzene as a feedstock at identical process conditions.
