ABSTRACT:
A process for eliminating organic pollutant residues in the synthesis gas occurring during refuse gasification by the addition of oxygen, in which at least prepyrolyzed, carbon-containing refuse in compressed form is fed into a high temperature reactor, where a loosely heaped gasification bed is formed and is burnt below the same by oxygen addition. The resulting synthesis gas is drawn off from the top area of the high temperature reactor after an adequate residence time and into the residence zone. Additional oxygen is then jetted in temperature-regulated, partial quantities in such a way that the resulting possible partial combustion of the synthesis gas maintains its temperature above the gasification bed constant at approximately 1000.degree. C. Oxygen jetting takes place in such a way that a completely homogeneous gas mixing is ensured in the top area. For this purpose, several oxygen jets are arranged in the top area of the high temperature reactor and are axially and/or radially inclined thereto.
