Heterogeneous metal-based catalysts for cyclohexane synthesis from hydrodeoxygenation of lignin-derived phenolics

Selective C(aryl)–O bond cleavage in biorenewable phenolics

“…Transformation of phenolics (guaiacols and syringols) into cyclohexane by unselective upgrading (hydrodeoxygenation and arene reduction) for biofuel application has recently been reviewed 52 and is beyond the scope of this review focussing on selective upgrading towards specific platform molecules and products for commodity, fine and specialty chemicals synthesis.…”

Boosting the Hydrodeoxygenation Activity and Selectivity of Ni/(M)-SBA-15 Catalysts by Chemical Alteration of the Support

“…6−15 Nickel-based catalysts are an alternative to noble metals, primarily due to their lower cost and high activity. 13,16,17 On the other hand, different kinds of ordered mesoporous materials, such as MCM-41, SBA-15, SBA-16, KIT-6, and others, have garnered significant attention as supports for heterogeneous catalysts. 18−20 In the field of HDO of bio-oil model compounds, the use of different Ni catalysts supported on SBA-15-type materials has been reported in the literature.…”

“…Catalysts based on noble metals such as Pt, Pd, Rh, and Ru supported on different materials have been investigated in HDO of different model compounds, obtaining high yields of hydrocarbons. − Nickel-based catalysts are an alternative to noble metals, primarily due to their lower cost and high activity. ,, On the other hand, different kinds of ordered mesoporous materials, such as MCM-41, SBA-15, SBA-16, KIT-6, and others, have garnered significant attention as supports for heterogeneous catalysts. − In the field of HDO of bio-oil model compounds, the use of different Ni catalysts supported on SBA-15-type materials has been reported in the literature. For instance, hydrotreating of a mixture of methyl esters was conducted over Ni and Co catalysts supported on SBA-15 and Al-SBA-15 .…”

Highly Efficient Catalytic Hydrodeoxygenation for Aliphatic Acid to Liquid Alkane: The Role of Molybdenum

“…Biodiesel can be one choice for the production of biomass fuels [3]. Aliphatic acid methyl esters (FAMEs) produced by the transesterification of triglycerides are considered the first generation of biodiesel, but the high viscosities and low cloud points limit their utilization [4][5][6]. While long-chain aliphatic hydrocarbons produced by hydrodeoxygenation (HDO) are considered to be second-generation biodiesel, the conversion of aliphatic acids is generally considered to be harder than the formation of them from triglycerides during the HDO process.…”
