TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The hydrogenation/dehydrogenation catalyst includes: at least one metal or a corresponding metal compound consisting of iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium or platinum, preferably platinum or a platinum compound; or a metal or corresponding metal compound consisting of rhenium, tin, germanium, gallium, indium, lead, and/or tin. The olefin metathesis catalyst comprises: a metal or a corresponding metal compound consisting of tungsten, molybdenum, tin or rhenium; or tungsten (preferred). The hydrogenation/dehydrogenation catalyst is platinum-on-alumina and the olefin metathesis catalyst is tungsten-on-silica. The volumetric ratio of the platinum component to the tungsten component is greater than 1:50 to less than 50:1, preferably 1:10-10:1. The amount of platinum on the alumina is 0.01-10 (preferably 0.1-5) wt.% and the amount of tungsten on the silica is 0.01-50 (preferably 0.1-20) wt.%.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process further comprises: (d) recovering the light n-paraffinic biologically derived product from step (c), and (e) recovering the heavy n-paraffinic biologically derived product from step (c); an isomerization step of the n-paraffinic product from step (b); an isomerization step of the second effluent mixture from step (c); and an isomerization step of the light n-paraffinic biologically derived product and/or heavy n-paraffinic biologically derived product. The step (c) further comprises treatment of the n-paraffinic product of step (b) with a hydrogenation/dehydrogenation catalyst and an olefin metathesis catalyst under conditions which dehydrogenate the paraffins to olefins, metathesize the olefins, and hydrogenate the olefins to paraffins to provide a third effluent mixture comprising a light n-paraffinic biologically derived product and a heavy n-paraffinic biologically derived product. The step (c) further utilizes a process conditions including: a temperature of 400-1000 degrees F; a pressure of 50-3000 psig; and a liquid hourly space velocity of 0.1-5 hour-1. The step (a) further utilizes a process conditions including: a temperature for hydrotreating of 300-750 degrees F; a total reaction pressure for hydrotreating of 50-3000 psig; a liquid hourly space velocity for hydrotreating of 0.1-5 hour-1; and a hydrogen feed rate for hydrotreating of 0.1 to 20 MSCF/bbl. Preferred Components: The triglyceride is a mixture of triglycerides. EXAMPLE - No suitable example given.
