NOVELTY - Partial gasification of solid organic feedstock, comprises obtaining a tar-containing carbonization gas from the feedstock by low-temperature carbonization in a low-temperature gasifier (1); converting carbonization gas by partial oxidation and subsequent partial reduction in a high-temperature gasifier (2) to form a synthesis gas; dedusting the synthesis gas in a dedusting system (4) and cleaning in a gas scrubber (5); and separating the residual coke from the synthesis gas and at least partly supplying to support the reduction of the high-temperature gasifier.    USE - The method is useful for partial gasification of solid organic feedstock (claimed).    ADVANTAGE - The method optimizes pyrolysis coke quality and quantity; and allows compensation of a fluctuating demand for pyrolysis coke in a simple manner.    DETAILED DESCRIPTION - Partial gasification of solid organic feedstock, comprises obtaining a tar-containing carbonization gas from the feedstock by low-temperature carbonization in a low-temperature gasifier (1); converting carbonization gas by partial oxidation and subsequent partial reduction in a high-temperature gasifier (2) to form a synthesis gas; dedusting the synthesis gas in a dedusting system (4) and cleaning in a gas scrubber (5); and separating the residual coke from the synthesis gas and at least partly supplying to support the reduction of the high-temperature gasifier. The residual coke remains in a pressure atmosphere, in which the same or higher pressure prevails, and the temperature is same as in a dust collector. An INDEPENDENT CLAIM is also included for a plant for carrying out the above mentioned method comprising a low temperature gasifier, a high-temperature gasifier, a gas cooling device (3), a dedusting system and a gas scrubber. The low temperature gasifier is coupled to atmosphere pressure, where the residual coke is introduced into the high-temperature gasifier by a pneumatic conveyor.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the plant.
