Efficient hydrothermal deoxygenation of methyl palmitate to diesel-like hydrocarbons on carbon encapsulated

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 2,   Pages 139-155 doi: 10.1007/s11705-022-2217-4

Abstract: Porous carbon-encapsulated Ni and Ni–Sn intermetallic compound catalysts were prepared by the one-pot extended Stöber method followed by carbonization and tested for in-situ hydrothermal deoxygenation of methyl palmitate with methanol as the hydrogen donor. During the catalyst preparation, Sn doping reduces the size of carbon spheres, and the formation of Ni–Sn intermetallic compounds restrain the graphitization, contributing to larger pore volume and pore diameter. Consequently, a more facile mass transfer occurs in carbon-encapsulated Ni–Sn intermetallic compound catalysts than in carbon-encapsulated Ni catalysts. During the in-situ hydrothermal deoxygenation, the synergism between Ni and Sn favors palmitic acid hydrogenation to a highly reactive hexadecanal that easily either decarbonylate to n-pentadecane or is hydrogenated to hexadecanol. At high reaction temperature, hexadecanol undergoes dehydrogenation–decarbonylation, generating n-pentadecane. Also, the C–C bond hydrolysis and methanation are suppressed on Ni–Sn intermetallic compounds, favorable for increasing the carbon yield and reducing the H2 consumption. The n-pentadecane and n-hexadecane yields reached 88.1% and 92.8% on carbon-encapsulated Ni3Sn2 intermetallic compound at 330 °C. After washing and H2 reduction, the carbon-encapsulated Ni3Sn2 intermetallic compound remains stable during three recycling cycles. This is ascribed to the carbon confinement that effectively suppresses the sintering and loss of metal particles under harsh hydrothermal conditions.

Deciphering the intermolecular interactions for separating bicyclic and tricyclic aromatics via different naphthalene-based solvents

Frontiers of Chemical Science and Engineering doi: 10.1007/s11705-024-2462-9

Abstract: The traditional separation of bicyclic and tricyclic aromatics from coal tar involves complicated multi-steps and consumes significantly more energy. Previous work accomplished the separation between anthracene-phenanthrene isomers using electrostatic interaction, but for the separation between bicyclic and tricyclic aromatics, electrostatic interactions are difficult to produce a recognizable effect. Naphthalene-based solvents, named as naphthaleneacetamide, naphthaleneethanol, naphthalenemethanol, naphthol, naphthylacetic acid, naphthylacetonitrile, and naphthylamine, respectively, were used for the efficient separation of naphthalene and phenanthrene via dispersion interaction. Results showed that the pre-studied structural parameters are the key factors in selecting an efficient solvent. And the substituents on the intermolecular interactions involved in the separation processes had an important impact, which were evaluated. Naphthalenemethanol exhibited a superior performance with a purity of 96.3 wt % naphthalene products because its electron-donating substituent enables the selective recognition of naphthalene via the dispersion interaction. The used naphthalene-based solvents can be regenerated and recycled via back extraction with a purity of over 90 wt % naphthalene products, suggesting solvent structural stability during the regeneration processes. Notably, the naphthalene-based solvents also demonstrated better separation performance for polycyclic aromatics from coal tar with a purity of over 80 wt % for bicyclic aromatics. This study would enhance the utilization of coal tar as a valuable source of polycyclic aromatics besides broadening the knowledge for applying non-bonded interaction in the separation of polycyclic aromatics technologies.
