Title:
PROCESSING OF OFF-GAS FROM WASTE TREATMENT
Document Type and Number:
WIPO Patent Application WO/2010/073008
Kind Code:
A3
Abstract:
Waste treatment comprises heating it in a chamber to effect pyrolysis of the waste, introducing oxygen into the chamber to effect combustion of the pyrolyzed waste, and contacting off-gas from the pyrolysis and/or combustion steps with an oxidation catalyst to convert carbon monoxide and hydrocarbons in the off-gas into carbon dioxide and water and with a reduction catalyst to convert nitrous oxides to nitrogen and oxygen. Thus, domestic waste is treated in a batch process using catalytic converters to reduce the level of toxic components before off-gas reaches the atmosphere.
