System for treating renewable feedstocks
A system that includes a feedstock of a non-petroleum or renewable feedstock containing oxygen and contaminants of one or more of metals, gums, and resins that is introduced into the reactor at a flow velocity of from 20 ft/sec to 100 ft/sec. The feedstock is heated within the reactor to a temperature of from 700° F. to 1100° F. to remove and/or reduce the content of one or more of gums and resins in the fats and/or oils of the feedstock. The system further includes a reactor product that is formed in the reactor from the feedstock that has the one or more of gums and resins in the fats and/or oils of the feedstock removed and/or reduced and a heat exchanger to cool the reactor product. A separator unit separates and removes non-condensable gases, metals and water from the cooled reactor product. A final product of the system is separated from the non-condensable gases, metals and water from the cooled reactor product. The final product has an oxygen content that is 60% or less of that of the feedstock, and wherein the final product comprises 25 wt % or less of any triglycerides, monoglycerides, diglycerides, free fatty acids, phosphatides, sterols, tocopherols, tocotrienols, and fatty alcohols, from 5 wt % to 30 wt % naphtha, and 50 wt % or more diesel.

Branched paraffinic compositions derived from isomerized and hydrogenated linear alpha olefins
Compositions can include mixtures having from about 2 wt % to about 40 wt % of C.sub.10-C.sub.20 linear paraffins based on the weight of the mixture, from about 60 wt % to about 98 wt % of C.sub.10-C.sub.20 branched saturated hydrocarbons based on the weight of the mixture, and less than or equal to about 30 wt % of C.sub.20+ saturated hydrocarbons based on the weight of the mixture. Methods to obtain these compositions can include the isomerization of one or more C.sub.10-C.sub.20 alpha olefins under skeletal isomerization conditions to obtain an isomerization mixture and the hydrotreating of the isomerization mixture.

Method for Treating Renewable Feedstocks
A non-petroleum or renewable feedstock containing oxygen and contaminants of metals, gums, and resins is treated by introducing the feedstock into a reactor at a flow velocity of at least 20 ft/sec. The feedstock is heated within the reactor and cooled to form a reduced-temperature reactor product. At least a portion of the reduced-temperature reactor product is feed into a hydroprocessing reactor containing a hydroprocessing catalyst to form a hydroprocessed product. The hydroprocessed product is cooled and non-condensable gases, metals and water are separated and removed to form a final product. The final product has an oxygen content that is 60% or less of that of the feedstock, and wherein the final product comprises 25 wt % or less any triglycerides, monoglycerides, diglycerides, free fatty acids, phosphatides, sterols, tocopherols, tocotrienols, or fatty alcohols, from 5 wt % to 30 wt % naphtha, and 50 wt % or more diesel.
