TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process further comprises recycling a portion of the stream comprising paraffins to the first reaction zone at a volume ratio of recycle to feedstock of 2:1- 8:1. The process further comprises pre-treating the feedstock in a pretreatment zone at pretreatment conditions to remove at least a portion of contaminants in the feedstock. The deoxygenating comprises at least one of decarboxylation, decarbonylation, and hydrodeoxygenation. The process further comprises separating carbon dioxide from the stream comprising hydrogen and carbon dioxide and recycling the remaining hydrogen to the first reaction zone. The process further comprises treating a petroleum derived hydrocarbon in the first reaction zone with the renewable feedstock. The treating of the feedstock in the first reaction zone is additionally in the presence of at least one sulfur-containing component and the process further comprises separating the carbon dioxide and the sulfur-component from the stream comprising hydrogen and carbon dioxide and recycling the remaining hydrogen to the first reaction zone. The process further comprises removing at least a portion of the hydrogen from the branched paraffin rich stream. The process further comprises recycling the hydrogen removed from the branched paraffin-rich stream to the hot high pressure hydrogen stripper. The process further comprises recycling at least a portion of the branched paraffin-rich stream to the second reaction zone. The alcohol denaturing process comprises mixing the alcohol with the denaturant. The reaction conditions in the first reaction zone include at a temperature of 40-400 degrees C and a pressure of 689-13790 kPa absolute. The isomerization conditions in the second reaction zone include at a temperature of 40-400 degrees C and a pressure of 689-13790 kPa absolute. The hot high pressure hydrogen stripper is operated at 40-300 degrees C and a pressure of 689-13790 kPa absolute. The second reaction zone is operated at a pressure of at least 345 kPa absolute (50 psia) greater than that of the first reaction zone. Preferred Components: The alcohol is ethanol. EXAMPLE - None given.
