Comparison of Green Extraction Processes to Valorize Lignin from Five Different Biomass Waste Types as Antistatic Agent in Fuel

Short Introductive summary

Pumping fuels through pipelines over long distances entails a high risk of electrostatic charging due to friction in these pipes. The Stadis 450, with its active ingredient dinonylnaphthylsulfonic acid (DINNSA), is the antistatic agent added to certain fuels. However, this active ingredient is highly flammable, toxic to humans, and the environment. Wood naturally possesses antistatic properties. It has been proven that this specificity is due to the presence of lignin in wood (Özel et al., 2020). This property of lignin is already being exploited in the design of new materials (Abdel Aal et al, 2022) and seems to be a promising avenue for fuels. The aim of this work is to determine the relevant lignin structure for its application as antistatic agent in fuel. To reach this goal, lignin from five local French or Belgium co- products with different content of lignin and structure was extracted with green fractionation process (Organosolv and DES). A complete characterization of this lignin was performed to identify the more appropriate structure for application as antistatic agent.
