Embodiments of methods for making renewable diesel by deoxygenating fatty acids to produce hydrocarbons are disclosed. Fatty acids are exposed to a catalyst selected from a) M1 /M2 /M3O2 where M1 is a transition metal, a transition metal oxide, or a combination thereof, wherein the transition metal is Fe, Mn, Mo, V, or W, M2 is Pt, PtO, PtO2, or a combination thereof, and M3 is Ti or Zr, or b) Pt/Ge or Pt/Sn on carbon, and the catalyst decarboxylates at least 10% of the fatty acids. Deoxygenation is performed without added hydrogen and at less than 100 psi. Disclosed embodiments of the catalysts deoxygenate at least 10% of fatty acids in a fatty acid feed, and remain capable of deoxygenating fatty acids for at least 200 minutes to more than 350 hours.
把脂肪酸脱氧化制备烃类可再生柴油的方法实施例被披露。脂肪酸暴露于选择自a) M1/M2/M3O2的催化剂,其中M1是过渡金属、过渡金属氧化物或二者的组合,过渡金属为Fe、Mn、Mo、V或W,M2是Pt、PtO、PtO2或二者的组合,M3是Ti或Zr,或b) Pt/Ge或Pt/Sn载于碳上,催化剂脱羧化至少10%的脂肪酸。脱氧化在不添加氢气且低于100 psi的条件下进行。披露的催化剂实施例能够脱氧化脂肪酸饲料中至少10%的脂肪酸,并且能够持续脱氧化脂肪酸至少200分钟至超过350小时。
