“…Thereinto, Ni 0.44 MoCN owns the highest pentadecane selectivity of 42.6% followed by Ni 0.30 MoCN (36.4%), Ni 0.18 MoCN (14.1%), Ni 0.12 MoCN (12.4%), and MoCN (2.7%), indicating that the cleavage of C–C bonds is strengthened. As reported, the Ni-based catalysts exhibited non-negligible ability for the cleavage of C–C bonds. ,,− However, the cleavage of C–C bonds is weak among Mo-based catalysts including the Mo 2 C catalyst, which is also in accordance with the activity and selectivity of the MoCN catalyst. , It can be concluded that the addition of Ni makes for the regioselectivity cleavage of C–C bonds adjacent to carbonyl groups at a certain degree. The related cleavage of C–C bonds over Ni x MoCN is dependent on the metallic sites of Ni species.…”

The rational exploit of fatty esters to obtain clean fuels can effectively solve the problems of energy depletion and carbon emission. The challenges are the optimal catalytic process and the development of highly efficient catalysts for the removal of oxygen from fatty esters in bioenergy. Herein, nickel molybdenum carbonitride (Ni x MoCN) nanostructures with low cost and Pt-like properties are simply obtained from one-step pyrolysis of a self-assembly NiMo-based organic–inorganic precursor and tested in the deoxygenation of methyl palmitate. The introduced Ni plays a great role in the phase composition and catalytic properties of Ni x MoCN with steerable nanoheterostructures. Regioselectivity cleavage of C–O and C–C bonds exists over Ni x MoCN nanocatalysts. The optimal Ni0.30MoCN with 49% β-Mo2C and 51% Ni2Mo3N shows 98.3% conversion and 100% deoxygenation degree, which are much higher than those of MoCN with a β-Mo2C phase (only 12.4% conversion and 51% deoxygenation degree at a contact time 0.35 min under 300 °C and 0.1 MPa). The main reaction route over the MoCN nanocatalyst is hydrodeoxygenation of methyl palmitate, while the hydrodeoxygenation and decarbonylation/decarboxylation of methyl palmitate compete over the Ni0.30MoCN nanocatalyst.

“…Recently, the sulfur‐free transition metal catalysts such as non‐noble Ni, Co, and Mo in addition to noble Pd and Pt supported on Al 2 O 3 , SiO 2 , TiO 2 , and carbons have been generally utilized for the hydrodeoxygenation process; [1a,2a,3d,11] meanwhile, the bifunctional catalysts with dual metal and acid sites on proper support materials have been also designed for the hydro‐isomerization and cracking reactions [6c,9,12] . In typical hydro‐isomerization and cracking reactions, the metal sites such as Pt and Ni are utilized for the dehydrogenation of alkanes intermediates into alkenes, followed by the protonation to n ‐alkylcarbenium ion and rearrangement to iso‐alkanes or β ‐scission into shorter chain‐alkanes on acid sites such as zeolites‐ZSM series, Beta, and silicoaluminophosphates (SAPO series) [9,13] .…”

The novel bifunctional NiÀ Re supported on bimodal SAPO-11 catalyst was designed for an economically combined process of direct triglycerides hydro-deoxygenation and isomerization into low-cold flow diesel. The catalyst with a Ni to Re molar ratio of 1 : 0.12 exhibited superior performance for diesel production containing large fraction of iso-alkanes in comparison to Ni and Re benchmarks. Comprehensive characterizations revealed that the detection of Ni and Re co-existed with NiO and ReO x on SAPO-11 after the reduction confirmed by XRD, XANES, and XPS analysis gave a large distribution of Lewis acid sites (> 80 %) noticed by Pyridine-DRIFTS measurement. Under investigations of WHSV, reaction temperature, and H 2 pressure, the NiRe 0.12 catalyst contributed a nearly theoretical 77.1 % liquid yield, accompanied by a 18.2 % jet-range and 52.1 % diesel-range yields with a classification for 46.8 % iso-alkanes and 23.5 % normal alkanes yields; whereas, the cold-flow properties of liquid product were in the ranges of winter diesel standard. It was remarkably noticed that the combination effects of Ni and nanosized Re species substantially improved the diesel production comprising iso-alkanes components with proper catalyst lifetime and low carbon deposition attributing to the fabricated active metal species on bimodal SAPO-11 features with large distribution of Lewis acidic sites.
