Biomass conversion into bio-based chemicals and high-value compounds (part 1)
Production of Bio-Based Chelated Copper Micronutrient Fertilisers Using Pyroligneous Acid Derived from Biomass Resources
Short Introductive summary
The optimisation of oxidation conditions for creating a new advanced chelated micronutrient – copper (Cu) chelate from PA was finally studied (Chapter 6). A comparison of solubility performance between copper-PA and other industry reagents of EDTA, glycine, and LSA-based copper showed that PA excel with 99% solubility and 80% solubility at pH = 6 and pH = 8. At the optimal oxidation condition of 240 minutes and pH = 2, half of the phenolics in PA were degraded to create a product that can hold 7.5% of copper in alkaline soil. PA was on par with LSA chelation capability in soil, and indicated a good prospect for agricultural applications.
