Grundlagenentwicklung und Optimierung eines Plasmatrons zum Einsatz fuer die Hochtemperaturpyrolose von chlorierten Kohlenwasserstoffen Abschlussbericht

A test stand composed of a 15 kW argon thermal plasma source, mixing and reaction chamber, a quenching section and an exhaust gas cleaning device was set up to investigate the advanced decomposition method for chlorinated hydrocarbons. The type of plasma is a DC-arc-generated thermal plasma, produced by a plasma torch derived from arc jet thrusters for space application. First experiments were performed using model substances including trichlorethylen as a chlorinated hydrocarbon model molecule allowing the simulation of decomposition and reaction steps. Analysis results indicate that nearly all chlorine is converted into hydrogenchlorine gas and solubilized in the water. In a parallel study a mathematical quasi 1D flow model of the system was developed, which includes a complex reaction mechanism. The whole reactor from the injection down to the quenching section has been simulated.
