“…Hydrolytic lignin is one of the large-scale produced non-demanded carbon materials, which due to its low reactivity is not widely used as a source of carbon feedstock for further processing [ 3 , 4 , 5 , 6 ]. Currently, the interest of researchers is focused on the development of various methods of lignin depolymerization: pyrolysis [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ], gasification [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ], depolymerization assisted by microwave radiation [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ], catalytic hydrogenation [ 30 , 31 ], electrochemical methods [ 32 ], etc.…”

Hydrolytic lignin is one of the non-demanded carbon materials. Its CO2-assisted conversion is an important way to utilize it. The use of the catalysts prepared by metal deposition on the surface of hydrolytic lignin makes it possible to apply milder conditions of the conversion process with CO2 and to improve the economic indicators. The development of methods of deposition of the active phase is a problem of high importance for any heterogeneous catalytic processes. This work aimed at investigating the influence of the conditions of iron deposition on the surface of hydrolytic lignin on the process of CO2-assisted conversion of lignin. Different Fe precursors (Fe(NO3)3, FeSO4, Fe2(SO4)3), solvents (water, isopropanol, acetone, and ethanol), and concentrations of the solution were used; the properties of Fe/lignin composites were estimated by SEM, EDX, TEM, XRD methods and catalytic tests. All the prepared samples demonstrate a higher conversion compared to starting lignin itself in the carbon dioxide-assisted conversion process. The carbon dioxide conversion was up to 66% at 800 °C for the sample prepared from Fe(NO3)3 using a twofold water volume compared to incipient wetness water volume as a solvent (vs. 39% for pure lignin).

“…Its widespread availability makes this biomass feedstock a renewable raw material for the modern chemical industry. [1][2][3][4][5] The most important sources of lignocellulosic biomass are forestry (hardwood and softwood) and agricultural (e.g., corncob, corn stover, rice straw and wheat straw) wastes along with fast-growing perennial grasses like switchgrass. 6 An impeding factor, however, is lignocellulose's resistance towards chemical and biological conversion.…”
