“…Among the three hitherto reported methods for the deoxygenation of fatty acids, hydrodeoxygenation, which produces hydrocarbons without cleavage of C−C bonds in the fatty acids, is more atom‐efficient than decarbonylation and decarboxylation, which also cleave C−C bonds in fatty acids ,,. In previous studies, most supported catalysts (Pt, Pd, Ru, Rh, Fe, and Ni) suffer from high selectivity toward decarbonylation or decarboxylation products rather than hydrodeoxygenation products even under an atmosphere of H 2 . Only a few catalysts, including Ni‐loaded H‐beta zeolite, Pt−Re/ZSM‐5, Pd/Nb 2 O 5 /SiO 2 , W‐ or Mo‐based catalysts,, as well as Ni−Mo/Al 2 O 3 and hydrodesulfurization catalysts (sulfided NiMo oxides) catalyze the selective hydrodeoxygenation of fatty acids under increased pressure of H 2 .…”

The development of heterogeneous catalysts for green chemical synthesis is currently a growing area in catalysis and sustainable chemistry. Especially the use of renewable carbon resources such as carbon dioxide (CO2) and biomass‐derived compounds (e. g. carboxylic acids, esters, and amides) represent highly attractive research targets. As these substances reside in a high oxidation state, efficient reduction processes are required in order to convert these substrates into useful and value‐added chemicals. Moreover, in the interest of mass production, these substrates should be reduced by molecular H2 and a heterogeneous catalyst. In this context, our group has developed advanced catalysts and established design guidelines for catalysts that promote the reductive transformations of carboxylic acid derivatives and CO2. Our studies show that cooperative catalysis between Lewis‐acidic sites on the catalyst support and supported metal nanoparticles are crucial for the success of these challenging hydrogenations. In this review, we summarize the results of our recent studies on the direct synthesis of value‐added chemicals from CO2 and carboxylic acid derivatives using supported transition‐metal catalysts, and we propose a design concept for heterogeneous catalysts that promote these processes.

“…The yield of n-C 17 alkane is over 60%, olefins and polymers are also produced with these products [13]. Yang et al [14] prepared Pt/ZIF-67/zeolite 5A catalyst for oleic acid HDO and found that the oleic acid is completely transformed at 320 • C/2.0 MPa when Pt loading is only 0.5% due to the special structure of the studied catalyst. Good at stearic acid HDO reaction is 2% Ru/TiO 2 .…”

Effect of Surface Composition and Structure of the Mesoporous Ni/KIT-6 Catalyst on Catalytic Hydrodeoxygenation Performance

A series of Ni/KIT6 catalyst precursors with 25 wt.% Ni loading amount were reduced in H 2 at 400, 450, 500, and 550 • C, respectively. The studied catalysts were investigated by XRD, Quasi in-situ XPS, BET, TEM, and H 2 -TPD/Ranalysis methods. It was found that reduction temperature is an important factor affecting the hydrodeoxygenation (HDO) performance of the studied catalysts because of the Strong Metal Support Interaction Effect (SMSI). The reduction temperature influences mainly the content of active components, crystal size, and the abilityfor adsorbing and activating H 2 . The developed pore structure and large specific surface area of the KIT-6 support favored the Ni dispersion. The RT450 catalyst, which was prepared in H 2 atmosphere at 450 • C, has the best HDO performance. Ethyl acetate can be completely transformed and maintain 96.8% ethane selectivity and 3.2% methane selectivity at 300 • C. The calculated apparent activation energies of the prepared catalysts increased in the following order: RT550 > RT400 > RT500 > RT450.
