The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction
The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The method also includes separating the naphtha fraction and optionally recycling the hydrocracking unit heavy fraction through the hydrocracking unit. The present invention also relates to a biorenewable naphtha product suitable for use as feed stock for steam crackers and catalytic reforming units, and for use as fuel, or fuel blend stock.

1. A naphtha boiling range hydrocarbon composition derived from a biorenewable feedstock having monoglycerides, diglycerides, triglycerides, free fatty acids, or combinations thereof, the composition comprising: n-paraffins, iso-paraffins, aromatics, and naphthenes;wherein the composition is produced by hydrocracking a hydrotreated biorenewable feedstock;comprises C4, C5, C6, C7, C8, and C9 hydrocarbons;is greater than about 80% by weight of total n- and iso-paraffins;has a Research Octane Number of less than about 40; andhas a Reid Vapor Pressure of greater than about 10 psi. 2. The composition of claim 1, wherein the composition has a specific gravity at 20° C. of from about 0.680 to about 0.740. 3. The composition of claim 1, wherein the paraffins comprise C4, C5, C6, C7, C8, C9, and C10 paraffins. 4. The composition of claim 1, wherein the biorenewable feedstock is selected from the group comprising animal fats, animal oils, poultry fat, poultry oil, vegetable fats, vegetable oils, rendered fats, rendered oils, restaurant grease, brown grease, waste industrial frying oils, fish oils, fish fats, and combinations thereof. 5. The composition of claim 1, comprising: greater than about 90% by weight of total n- and iso-paraffins. 6. The composition of claim 1, comprising: less than about 0.5% by weight of olefins. 7. The composition of claim 1, comprising: less than about 6.5% by weight of naphthenes. 8. The composition of claim 1, comprising: less than about 1.0% by weight of total aromatics. 9. The composition of claim 1, wherein the composition is free of benzene.
