HIGH ENERGY GAS FLOW TYRE PYROLYSIS USING RF INDUCTIVE PLASMA IN COMBINATION WITH IF INDUCTION HEATINGAbstractThe present invention relates to a High Energy Gas Flow Tyre Pyrolysis using our technology of RF Inductive Plasma in combination with LF Induction Heating, which controls both the atmosphere and temperature of the pyrolysis process to convert waste tyres to energy. Our technology involves the use of an RF induced plasma torch coupled with careful process design parameters, operational flexibility, and an oxygen-deprived atmosphere where the pyrolysis occurs. RF torch plasma is a much more flexible pyrolysis technique because the hot plasma field is formed by passing gas through an RF induction coil. This allows different gasses to be used to control the end result and also eliminates the need to shut down the reactor to replace electrodes. The pyrolysis takes place in oxygen starved and high heat atmosphere that does not allow, in the alternate, destroys the ability for dioxins, furans, and other hazardous by-products to be produced. The different gas compositions from the tyre pyrolysis, unlike the solid fraction, are not only affected by the reaction temperature but also by the process dwell times, type of plasma gas and type of carrier gas. This variability of inputs provides the ability to produce a range of quantities of the output constituents. Combine with Induction heating, this is designed to provide high temperature to a conduit tube attached to the RF Plasma outlet. The induction heating is accomplished using this conduit tube as the heat sink. The tube then radiates and convectively heats the passing gasses, liquids and solids. This tube operates at relatively high temperatures (9009 C). Since this invention includes an RF plasma torch in-line with an LF Induction heater. The LF Induction Heater will have an angle. This will create a fluidized bath and will allow the variation of the rubber particle dwell time. This added dwell time breaks down any heavy oils leaving the Plasma torch in long chain hydrocarbon gasses that are used to increase the heating value of the syngas to produce energy from waste tyres.
