Hydrotreatment of Lignin-Derived Phenolics
Our research group is focusing on the application of the mildest (“greenest”) conversion processes for the catalytic conversion of the different bio-originated feedstocks (bio-oil, lignin-derived phenolics etc.) onto the bio-originated chemicals.
Understanding the nature of chemical processes associated with the conversion of the lignin‑derived phenolics is an important way for further process optimization for useful chemicals production or phenolics-rich streams (pyrolysis aqueous phase) treatment for their utilization in wastewater treatment plants. Hydrotreatment of lignin-derived phenolic compounds over Raney-Ni with a continuous regeneration of the H-donor solvent can be a good opportunity how to produce valuable chemicals at mild reaction conditions. Here, the behaviour of different phenolics during hydrotreatment is discussed regarding their structure, followed by the upgrading of the phenolics mixture extracted from the pyrolysis oil aqueous phase
