Catalytic Hydrogenolysis of Lignin: The Influence of Minor Units and Saccharides

“…Among these, reductive catalytic fractionation (RCF) or catalytic hydrogenolysis of isolated lignin have been intensively studied as a lignin‐first bio‐refinery strategy with the potential to produce valuable alkyl phenolic monomers from lignin [23] . Various catalytic systems with metal‐based catalysts have been explored to produce functional aromatic monomers from different biomasses, and the product portfolio was shown to be tunable by the choice of catalyst and reaction conditions [24–26] . The monomers can be converted to marketable added‐value chemicals by catalytic funneling [22,27] .…”

“… [23] Various catalytic systems with metal‐based catalysts have been explored to produce functional aromatic monomers from different biomasses, and the product portfolio was shown to be tunable by the choice of catalyst and reaction conditions. [ 24 , 25 , 26 ] The monomers can be converted to marketable added‐value chemicals by catalytic funneling. [ 22 , 27 ] These monomers are mainly obtained by the cleavage of the β‐O‐4 linkage and thus monomer yields closely correlate with the structure and composition of the staring material.…”

Boosting the Ni‐Catalyzed Hydrodeoxygenation (HDO) of Anisole Using Scrap Catalytic Converters

“…In addition, mechanochemistry has been pointed as a promising tool for a sustainable development due to its important scale-up properties, [58][59][60][61] key features for the making of a catalyst for biofuel production from aromatics. [62][63][64]…”

Bridging Scales in Bioenergy and Catalysis: A Review of Mesoscale Modeling Applications, Methods, and Future Directions

“…Carbohydrate-rich pulps are typically processed downstream of these steps using well-studied chemical , and/or biological treatments. Before all these, the pulp and paper industry had long optimized their commercial lignin removal processes using complex transport models, but investigations into the value-added conversion of native carbohydrates and lignin have typically emphasized catalyst discovery and/or detectable component yields (e.g., alkyl methoxyphenols) at long reactor residence times, , seldom incorporating heat, mass, and momentum transfer considerations. Transport phenomena are often specific to the starting feedstock and are difficult to decouple from kinetic measurements of catalyst behavior.…”
