A renewable lignin-derived bio-oil for boosting the oxidation stability of biodiesel

The valorisation of lignin is being increasingly recognised to improve the economics pulp and paper making mills. In present study, an integrated lignin–glycerol strategy introduced with overarching aim for enhancing process value chains. LignoBoost kraft was subjected base-catalysed depolymerisation using glycerol as a co-solvent. generated bio-oil used renewable additive biodiesel its oxygen stability. influence three independent parameters including temperature, time amount on investigated. Response surface methodology applied design experiments optimise maximising yield antioxidant impact bio-oil. results showed that has positive qualitative quantitative produced bio-oil, where enhancement in (up 23.8%) activity 99 min induction period) were achieved PetroOxy method (EN16091). addition 1 wt% led improvement oxidation stability over neat sample up ?340%, it compliant European standard (EN14214). proposed presents biorefinery paradigm utilisation waste cooking oil, glycerol.
