PRODUCTION METHOD OF SYNTHETIC GAS FROM LOW-CALORIAL BROWN COALS WITH HIGH-ASH AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC C10J3/00 C10J3/72 

FIELD: oil and gas industry.

SUBSTANCE: feedstock is subjected to disintegration, drying and gas generation in the field of the cyclonic swirl with the high temperature field applied to the swirling stream, where the part of the generated synthetic gas is supplied together with the high-temperature steam into the reaction chamber to activate the feedstock decomposition and increase the gas generation. The device contains the reaction chamber 4 with the power actuated screw pump 2, the swirler of the supplied superheated steam 24. The cavity of the chamber has the synthetic gas supply pipe to its purification 23, and it is also equipped with the part of the synthetic gas supply line again into the reaction area.

EFFECT: increase of the low-calorial brown coals gasification energy efficiency, productivity, synthetic gas quality, provision of the plant reliability.
