Document Type and Number:
Japanese Patent JP2000500702
Kind Code:
A
Abstract:
Waste (such as domestic garbage, industrial waste, and bulky refuse) or sewage sludge is pretreated by pyrolysis under an oxygen-poor atmosphere to provide solid pyrolysis residues and a pyrolysis gas. The solid pyrolysis residues are mechanically treated to provide a coarse fraction and a fine fraction. The coarse fraction is mechanically separated and fed to a metal bath reactor containing a metal bath and a liquid slag floating on the metal bath. The fine fraction entrained in a carrier gas is fed via a nozzle in order to carburize the metal bath. The carburized metal bath functions to reduce metal oxides from the liquid slag floated thereon, thereby purifying the liquid slag. At least a portion of the pyrolysis gas is used to smelt and heat the liquid slag.
