Title:
APPARATUS AND METHOD FOR THE TREATMENT OF WASTE
Document Type and Number:
WIPO Patent Application WO/2012/114110
Kind Code:
A3
Abstract:
Apparatus and method for the treatment of material are disclosed, for treating material such as waste material by the application of heat. A process container (10) includes heaters (13). Waste material is introduced into the process container (10) and is heated in the presence of little or no oxygen to a temperature sufficient to effect pyrolysis. Oxygen (14) is subsequently introduced into the process container (10) to effect (10) combustion of the waste material. An exhaust path E is provided for conveying exhaust gases from process container (10). An extracting gas flow is provided along an extracting path (300) which converges with the exhaust path E and assists in the extraction of exhaust gases from the chamber. The apparatus also has a primary catalyst (20) and a secondary catalyst (30). An input gas flow is provided along an inlet path (100,200) upstream of each catalyst, the inlet path (100,200) converging with the exhaust path E. The input gas flow can be used to heat and/or cool the catalyst, provide oxygen to the catalyst, and to control the flow of exhaust gas in exhaust path E.
