Nitrogen‐modified carbon nanotube‐supported ruthenium catalyst was demonstrated to be effective in the conversion of crude cyperus esculentus oil into linear liquid alkanes. The model compound stearic acid was nearly quantitatively converted into liquid alkanes, and the yields of n‐heptadecane and n‐octadecane were 89.5 % and 8.5 %, respectively. The mass yield of liquid alkanes from crude cyperus esculentus oil was 76.6 %, which was very close to the theoretical yield. The catalyst could be reused at least six times without loss of catalytic activity during the conversion of oil. We found that the nitrogen modification of the carbon nanotube support was beneficial to form more Ru 0 species, which exhibited excellent catalytic activity and stability towards the hydrodeoxygenation of stearic acid and plant oil.
