Abstract

A device for pyrolysis reactions includes a feeding pump, a flow meter, an atomizer, a pyrolysis reactor, electromagnetic coils, an electromagnetic induction heating power, a temperature sensor, a temperature controller, a condenser and a product tank. The feeding pump is connected with the flow meter which is connected to the inlet of the atomizer in the pyrolysis reactor. There is a port at the bottom of the pyrolysis reactor, with the port at the top of the pyrolysis reactor connected with the condenser. The condenser is connected with the product tank. The external wall of the pyrolysis reactor is surrounded by electromagnetic coils which are connected with the electromagnetic induction heating power. The temperature sensor is placed between the pyrolysis reactor and the coils, which is connected with the temperature controller. The contact resistance between the atomized material and the hot surface can be.
