METHOD AND DEVICE FOR PRODUCING COAL PYROLYSIS PRODUCTS Russian patent published in 2021 - IPC C10B1/00 F27B1/09 F27D11/08 

FIELD: carbonaceous materials.

SUBSTANCE: invention relates to the field of high-temperature processing of carbonaceous materials and can be used to obtain products of coal pyrolysis. The method consists in conducting high-temperature electric-discharge firing of lumpy carbon fractions in a hollow retort with the creation of a self-sintering shell on the outer surfaces of the fired lump carbon fractions. The method is implemented in a device for producing coal pyrolysis products, which includes a hollow retort made of graphite, a heat-insulating cover installed on the upper end of the hollow retort, upper and lower electrodes. The lower electrode is made in the form of a set of rings. The device contains an alternating voltage source, a steam generator connected by its output to the inner cavity of the lower section of the hollow retort, and a control system that supplies supply voltages through controlled switches to the upper and lower electrodes, to the first and second pumps, steam generator and refrigerator.

EFFECT: more uniform and high-temperature processing of lumpy carbon fractions and the homogeneity of the resulting material.
