FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Coal particles 4 with size of 1-8 mcm are placed inside a reactor 3, the volume of said particles making up 20-40% of the volume of the reactor. The reactor 3 is insulated from the surrounding medium by a cover 8. The particles 4 are then exposed for 12-17 minutes to an alternating rotating magnetic field whose strength, which is measured in the processing zone, is equal to 2.5·103-1·106 A/m and frequency is equal to 40-70 Hz. A jet of compressed air at excess pressure of 0.1-0.6 kgf/cm2 is fed into the obtained bottom residue 5 through a perforated pipe 6 whose end is closed and has through-holes 7, thereby forming a fluidised bed. Working members 1, which are connected to an external electric power supply and enable to form an alternating rotating magnetic field, are in form of mated plates made from magnetically conducting material, forming a closed rectangular loop in which three coil blocks 2 are placed.
EFFECT: invention enables to obtain graphite from cheap and readily available material at room temperature and pressure close to atmospheric pressure, low power consumption, simple process and design of the apparatus.
