7 atm is maintained in order to avoid oxygen entering the reactor during both stages of the pyrolysis ensuring the hermiticity of the pyrolysis reactor is a challenge at higher pressures it has been experimentally established that oxygen is very reliably prevented from entering the reactor at pressures higher than 0 15 atm the discharge tube 22 fig2 in the first part of a reactor is connected to the flange of tube 25 fig3 of the second part 3 of the reactor fig1 electromagnetic action on the pyrolysis products in the second part 3 of the reactor is created by the source 4 of the electromagnetic action in the form of the generator 23 connected with the discharge device group 24 mounted on tube 25 fig3 it is preferable to apply periodic electromagnetic action which is more effective for processing waste electromagnetic action is achieved by periodic electric discharge with a frequency from 3 to 500 hz with discharge voltage of 10 to 50 kv it has been experimentally established that depending on the choice of frequency a varied qualitative composition of hydrocarbons can be achieved the choice of the discharge voltage depends on the size of the pyrolysis reactor u2014 the smaller it is the lower the breakdown voltage the second part.
