“…The propylene is converted to propane, using hydrogen and high pressures. This is finally followed by the deoxygenation of the fatty acids through hydrodeoxygenation, decarboxylation, and decarbonylation . As described earlier, hydrotreating of vegetable oils results in the formation of CO, CO 2 and H 2 O, thus one potential concern with co‐processing vegetable oils with petroleum liquids is how it might impact desulfurization, as greater volumes of hydrogen will likely be required …”

“…During oxygen removal, the control of temperature in a reactor is important due to the relationship between hydrogen consumption and increases in temperature due to the exothermic nature of hydrodeoxygenation . The consumption of hydrogen was shown to be highest when using biogenic feedstocks, when the degree of feedstock unsaturation is greatest and when using higher temperatures . It has been shown that elevated temperatures can cause damage to some catalysts while also potentially resulting in unwanted secondary reactions, such as the formation of CH 4 from CO.…”

“…The catalytic hydrodeoxygenation of natural triglycerides using sulfided molybdenum catalysts on alumina supports with nickel and cobalt as the active metals has been well-studied in the literature. [1][2][3][4][5] It is an established technology that is used extensively for lipid biomass conversion to 'drop in' replacements for petroleumderived transportation fuels. One major drawback in using bimetallic sulfided catalysts is the inherent need for an external sulfiding agent such as carbon disulfide (CS2) or dimethyl disulfide (DMDS) in the liquid feed to maintain its catalytic activity.…”

“…Optimal reaction conditions for all investigations of this work were found to be 380°C, 50 bar H 2 pressure and a gas entrainment impeller rotation speed of 1100 RPM [5,7]. DO and HDO of fatty acids is widely discussed in literature [8][9][10][11][12][13][14][15]. HDO implies the direct participation of H 2 in a reaction, while DO in general does not necessarily require H 2 .…”
