Process for eliminating organic harmful substances in synthesis gas obtained by the gasification of municipal waste refuse

摘要

Removal of organic pollutants in synthesis gas produced in waste gasification comprises adding O2 so that pre-pyrolysed C-contg. waste is sealed in a high temp. reactor, which forms a gasification bed. The synthesis gas produced is removed in the top of the reactor after sufficient dwell time. The novelty is that additional O2 is injected into the free gas/gas of the reactor formed in the top region as the dwell zone, so that partial combustion of the synthesis gas occurs whose temp. is constantly maintained above the gasification bed at 1000 degrees C. O2 injection is carried out so that complete homogeneous gas mixing is guaranteed in the top region of the reactor.
