Abstract:
1. A process for controlling the simultaneous production of a diesel component comprising hydrocarbons having boiling points in the diesel fuel range and an aviation component comprising hydrocarbons having boiling points in the aviation fuel range from a renewable feedstock comprising: identifying target specifications required for the diesel component and for the aviation component; determining yields required for the diesel component and for the aviation component that meet the target specifications; determining a mixture of at least two renewable feedstocks having different carbon number distributions that results in the predetermined yields required for the diesel component and for the aviation component wherein the diesel component and the aviation component further meet the identified specifications; mixing the at least two renewable feedstocks to form the mixture; hydrogenating and deoxygenating the mixture by contacting the mixture in a hydrogenation and deoxygenation zone with a hydrogenation and deoxygenation catalyst at hydrogenation and deoxygenation conditions to provide a hydrogenation and deoxygenation zone effluent comprising n-paraffins; isomerizing at least a portion of the n-paraffins in the hydrogenation and deoxygenation zone effluent by contacting the n-paraffins with an isomerization catalyst in the presence of hydrogen at isomerization conditions in an isomerization zone to generate branched-paraffins in an isomerization zone effluent wherein the isomerization zone effluent comprises less than 5 wt. % of hydrocarbons having lower boiling points than the aviation component; and fractionating the isomerization zone effluent to provide a first product stream comprising the diesel component and a second product stream comprising the aviation component at substantially the predetermined yields and target specifications.
