Specifics of the stearic acid deoxygenation reaction on a copper catalyst

Decarbonylation of stearic acid, which is industrially manufactured from oils and fats, to higher olefins on a Cu/γ-Al2O 3catalyst has been first studied. It has been shown that the selectivity for heptadecenes is 67% and that for CO is close to 100% at 350°C. The activity of this catalyst in the further hydrogenation of resulting heptadecenes to heptadecane is well below that of a palladium catalyst. The conversion is slightly varied when hydrogen pressure increases from 4 to 14 bar; however, the selectivity for olefins increases and the selectivity for paraffins remains low. According to quantum-chemical simulation data, hydrides form on the surface of copper clusters in the presence of hydrogen. It is presumably these compounds that inhibit the side oligomerization reaction of olefins. The hydrogen-to-water concentration ratio does not affect the selectivity for CO and CO2; the only effect of the presence of water is a decrease in the stearic acid conversion rate.

Catalytic deoxygenation of bio-based 3-hydroxydecanoic acid to secondary alcohols and alkanes

This work comprises the selective deoxygenation of bio-derivable 3-hydroxydecanoic acid to either linear alkanes or secondary alcohols in aqueous phase and H2-atmosphere over supported metal catalysts. Among the screened catalysts, Ru-based systems were identified to be most active. By tailoring the catalyst, the product selectivity could be directed to either secondary alcohols or linear alkanes. In the absence of a Br?nsted acidic additive, 2-nonanol and 3-decanol were accessible with a yield of 79% and 6% respectively, both of which can be used in food and perfume industries as flavoring agents and fragrances. To produce alkanes, we successfully synthesized a bifunctional Ru/HZSM-5 catalyst. The acidic zeolite support facilitated the dehydration of the intermediary formed alcohols to alkenes, while the following hydrogenation occurred at the Ru centers. Thus, full 3-hydroxydecanoic acid deoxygenation to nonane and decane, which are both well-established as diesel and jet fuels, was achieved with up to 72% and 12% yield, respectively.

Effect of the presence of ionic liquid during the NiMoS bulk preparation in the transformation of decanoic acid

The impact of the presence and amount of [BMIM][NTf2] ionic liquid during the preparation of bulk NiMoS catalysts was investigated. It was clearly shown that these factors have a strong influence on both the morphology and specific surface area of the obtained NiMoS samples. Most interestingly the catalytic activity for the transformation of decanoic acid increased up to three times when IL was present during synthesis. In the same time, a greater selectivity towards hydrocarbons was observed. On the whole a clear relationship between catalytic activity, selectivity and NiMoS morphology was demonstrated. Consequently, it is possible to modify the morphology of the materials and impact the catalytic properties by changing the synthesis conditions.

Catalytic Upgrading of 5-Hydroxymethylfurfural to Drop-in Biofuels by Solid Base and Bifunctional Metal-Acid Catalysts

Design and synthesis of effective heterogeneous catalysts for the conversion of biomass intermediates into long chain hydrocarbon precursors and their subsequent deoxygenation to hydrocarbons is a viable strategy for upgrading lignocellulose into distillate range drop-in biofuels. Herein, we report a two-step process for upgrading 5-hydroxymethylfurfural (HMF) to C9 and C11 fuels with high yield and selectivity. The first step involves aldol condensation of HMF and acetone with a water tolerant solid base catalyst, zirconium carbonate (Zr(CO3)x), which gave 92 % C9-aldol product with high selectivity at nearly 100 % HMF conversion. The as-synthesised Zr(CO3)x was analysed by several analytical methods for elucidating its structural properties. Recyclability studies of Zr(CO3)x revealed a negligible loss of its activity after five consecutive cycles over 120 h of operation. Isolated aldol product from the first step was hydrodeoxygenated with a bifunctional Pd/Zeolite-β catalyst in ethanol, which showed quantitative conversion of the aldol product to n-nonane and 1-ethoxynonane with 40 and 56 % selectivity, respectively. 1-Ethoxynonane, a low oxygenate diesel range fuel, which we report for the first time in this paper, is believed to form through etherification of the hydroxymethyl group of the aldol product with ethanol followed by opening of the furan ring and hydrodeoxygenation of the ether intermediate. Two-stepping to Biofuels! A recyclable and water tolerant heterogeneous base catalyst produced 92 % C9-aldol product from 5-hydroxymethylfurfural and acetone in water. Subsequent hydrogenation of the isolated aldol product with a metal-acid Pd/zeolite-β catalyst produced gasoline and diesel range n-nonane and 1-ethoxynonane with an overall 96 % yield.

(Chemical Equation Presented) High-quality liquid fuels are obtained from non-edible carbohydrates by energy-efficient processes. 2-Methylfuran, produced by hydrogenation of furfural, is converted into 6-alkyl undecanes in a catalytic solvent-free process (see scheme with 6-butylundecane). A diesel fuel is produced with an excellent motor cetane number (71) and pour point (-90°C) and with global process conversions and selectivities close to 90%.

Alkanes from Bioderived Furans by using Metal Triflates and Palladium-Catalyzed Hydrodeoxygenation of Cyclic Ethers

Using a metal triflate and Pd/C as catalysts, alkanes were prepared from bioderived furans in a one-pot hydrodeoxygenation (HDO) process. During the reaction, the metal triflate plays a crucial role in the ring-opening HDO of furan compounds. The entire reaction process has goes through two major phases: at low temperatures, saturation of the exocyclic double bond and furan ring are catalyzed by Pd/C; at high temperatures, the HDO of saturated furan compounds is catalyzed by the metal triflate. The reaction mechanism was verified by analyzing the changes of the intermediates during the reaction. In addition, different metal triflates, solvents, and catalyst recycling were also investigated. Fu, Fu, Fu (tri-f): Metal triflates (tri-f) act as an axe (, Fu), cleaving the C-O bond of cyclic ethers and luckily (, Fu) transforming bioderived furans into alkanes in a one-pot (, Fu) process. The mechanism of the reaction is verified by analyzing the changes of the intermediates during the reaction. Different metal triflates, solvents, and catalyst recycling are investigated, also.

The method could be extended to non-geminal difluorides. The effect of the disilylated compound in the naphthalene-catalysed lithiation of fluorobenzene and benzyl fluoride was also studied.

Fabricating nickel phyllosilicate-like nanosheets to prepare a defect-rich catalyst for the one-pot conversion of lignin into hydrocarbons under mild conditions

The one-pot conversion of lignin biomass into high-grade hydrocarbon biofuels via catalytic hydrodeoxygenation (HDO) holds significant promise for renewable energy. A great challenge for this route involves developing efficient non-noble metal catalysts to obtain a high yield of hydrocarbons under relatively mild conditions. Herein, a high-performance catalyst has been prepared via the in situ reduction of Ni phyllosilicate-like nanosheets (Ni-PS) synthesized by a reduction-oxidation strategy at room temperature. The Ni-PS precursors are partly converted into Ni0 nanoparticles by in situ reduction and the rest remain as supports. The Si-containing supports are found to have strong interactions with the nickel species, hindering the aggregation of Ni0 particles and minimizing the Ni0 particle size. The catalyst contains abundant surface defects, weak Lewis acid sites and highly dispersed Ni0 particles. The catalyst exhibits excellent catalytic activity towards the depolymerization and HDO of the lignin model compound, 2-phenylethyl phenyl ether (PPE), and the enzymatic hydrolysis of lignin under mild conditions, with 98.3% cycloalkane yield for the HDO of PPE under 3 MPa H2 pressure at 160 °C and 40.4% hydrocarbon yield for that of lignin under 3 MPa H2 pressure at 240 °C, and its catalytic activity can compete with reported noble metal catalysts.
