One-step ethanolysis of lignin into small-molecular aromatic hydrocarbons over nano-SiC catalyst

WxC-β-SiC Nanocomposite Catalysts Used in Aqueous Phase Hydrogenation of Furfural

“…Composite materials contain Pd(0) and W 2 C particles well-dispersed on carbon were investigated as hydrogen evolution catalysis [ 44 ]. Recently, there have also been reports in the literature on the catalytic activity of SiC in the one-step ethanolysis of lignin into small-molecular aromatic hydrocarbons [ 45 ]. On this basis, systems containing W x C have clear potential to be used as catalysts in the process of furfural reduction.…”

Alternatives for Chemical and Biochemical Lignin Valorization: Hot Topics from a Bibliometric Analysis of the Research Published During the 2000–2016 Period

“…Simple noncatalytic solvolysis of biorefinery lignin in supercritical ethanol can produce a heptane soluble bio-oil without the need for the addition of a catalyst or a reducing agent [257]. The catalytic ethanolysis of lignin proposes the use of different catalysts: precious group metals (Pd, Pt, Ru, Rh …) and more abundant metals (Cu, Ni, Mo …) supported over oxides (alumina, ceria, zirconia, magnesia …) have been frequently reported [258][259][260][261], but alternative catalysts have been tested as well, such as silicon carbon nanoparticles [262] or ionic liquids [263]. Methanol have replaced ethanol in aqueous mixtures for lignin solvolysis with very similar results [264], while propanol and butanol have also been proposed [265].…”

Conversion of woody oil into bio-oil in a downdraft reactor using a novel silicon carbide foam supported MCM41 composite catalyst

“…Aer studying the zeolite membrane's characteristic and new processes of preparing porous SiC, an attractive method was put forwardforming the mesoporous molecular sieve on the surface of the porous SiC supportthis composite catalyst contains both the catalysis, adsorption, selection of 1 the molecular sieve and the chemical stability, good thermal conductivity, high mechanical strength of the silicon carbide. [16][17][18] In our previous study, the SiC performed the function of promoting the yield of aromatics in bio-oil. 19 Both SiC and MCM41 decreased the yield of the pyrolysis oil and increased the gas product.…”
