1. A process comprising:
a) obtaining a petroleum-derived hydrocarbon feed that comprises hydrocarbon compounds having a boiling point from about 25° C. to about 760° C.; b) heating the petroleum-derived hydrocarbon feed to a temperature ranging from about 100° C. to about 540° C. to produce a heated hydrocarbon feed; c) conveying the heated hydrocarbon feed to a thermal cracking zone; d) contacting a triglyceride feed with the heated hydrocarbon feed in the thermal cracking zone at a temperature ranging from about 100° C. to about 540° C. to form a thermally treated feed, wherein the contacting results in the thermal cracking of at least one contaminant derived from the triglyceride feed to form a decomposed contaminant, wherein the contaminant is selected from phospholipids, proteins, gums, metal containing compound and any combination thereof, wherein the metal containing compound is selected from alkali metals, alkaline earth metals, and any combination thereof, wherein the thermal cracking facilitates retention of the decomposed contaminant and prevents contact between the decomposed contaminant and the hydrotreating catalyst; e) conveying the thermally treated feed to a hydrotreating zone; f) hydrotreating the thermally treated feed with a hydrotreating catalyst in the hydrotreating zone at a temperature in the range of from about 260° C. to about 430° C. and a pressure ranging from 0 psig to about 2000 psig to produce a product containing diesel boiling range hydrocarbons, wherein hydrogen is added only downstream from the retention of the decomposed contaminant. |
