Abstract
A method of tire recycling, the method comprising the steps of: a) a hybrid plasma torch comprising an arc plasma torch and a radio frequency (RF) plasma torch generating a plasma jet in a first direction; b) injecting rubber powder obtained from comminuting waste tires into the plasma jet in a second direction against the first direction and obtaining a synthesis gas (syngas) by plasma pyrolysis of the rubber powder; c) heating unpyrolyzed rubber powder remaining after step b) in a low frequency (LF) induction heater to obtain carbon black; and d) using a portion of the obtained syngas as plasma gas by the hybrid plasma torch.

A method of tire recycling, the method comprising the steps of:
- a) generating a plasma jet in a first direction using a hybrid plasma torch comprising an arc plasma torch and a radio frequency (RF) plasma torch;
- b) injecting rubber powder obtained from comminuting waste tires into the plasma jet in a second direction against the first direction and obtaining a synthesis gas (syngas) by plasma pyrolysis of the rubber powder;
- c) heating unpyrolyzed rubber powder remaining after step b) in a low frequency (LF) induction heater to obtain carbon black;
- and
- d) using a portion of the obtained syngas as plasma gas by the hybrid plasma torch.
An apparatus for tire recycling, the apparatus comprising:
- a reaction chamber having a gas outlet;
- a hybrid plasma torch provided in the reaction chamber and configured to generate a plasma jet in a first direction in the reaction chamber, the hybrid plasma torch comprising an arc plasma torch and a radio frequency (RF) plasma torch;
- at least one feeding tube in fluid communication between the reaction chamber and a powder injector for injection of rubber powder obtained from comminuting waste tires into the plasma jet in a second direction against the first direction to obtain a synthesis gas (syngas) by plasma pyrolysis of the rubber powder;
- a low frequency (LF) heater in fluid communication with the reaction chamber for heating unpyrolyzed rubber powder that is flowed from the reaction chamber into the low frequency induction heater to obtain carbon black;
- wherein the hybrid plasma torch uses a portion of the obtained syngas as a plasma gas.
