Catalytic Deoxygenation of Fatty Acids and Their Derivatives
Abstract
Catalytic deoxygenation including decarboxylation/decarbonylation of fatty acids and their esters has been investigated over Pd supported on active carbons in a semibatch reactor. The main studied parameters were catalyst acidity, type of feed, effect of solvent, and gas atmosphere. High yields of the desired product, n -heptadecane, were achieved in the decarboxylation of stearic acid at 300 °C under helium. The results demonstrate that the catalytic transformation of fatty acids proceeded mainly via decarboxylation, whereas decarbonylation was the main route for esters, according to gas-phase analysis. The gas atmosphere and the acidity of the catalyst were important factors for determining product selectivity. Over alkaline catalysts as well as under a hydrogen atmosphere, higher yields of n -heptadecane were obtained. The decarboxylation of unsaturated fatty acids leads to hydrogenated products, which reacted further to hydrocarbons.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
