1. Pulsed corona discharge oxidation in lignin modification

2. Pulsed Corona Discharge (PCD) technology
Ultra-short gas-phase pulsed corona discharge generates OH-radicals from water
In-situ production of oxidants
ē + H2O = ē + ·H + ·OH
O (1D) + H2O = 2·OH
ē + 3O2 → ē + 2O3
Hydroxyl radicals are more effective than conventional oxidants such as oxygen, ozone, and chlorine
The main application:
Wastewater treatment removing organic impurities and metal ions

3. Lignin modification Objectives
Determination of chemistry and optimum operating conditions of lignin modification for its utilization in valuable products by oxidation at maximum cost efficiency.
possible products:
phenolic substances
aromatic aldehydes
vanilin, syringaldehyde,
vanillic acid,
syringic acid
