METHOD AND DEVICE FOR REGENERATING A PARTICULATE FILTER FOR EXHAUST LINE, AND ADAPTED PARTICULATE FILTER

摘要

The invention concerns a method for regenerating a particulate filter (2) for exhaust line (1), which consists in heating the particles lining the filter to bring them to a temperature higher than their combustion temperature. The invention is characterized in that it consists in: generating the heat required for heating said particles by adding to a first solid compound present in a reactor (6) a second compound in gas form combining with said first compound to form a third solid compound by exothermal reaction; and using the heat resulting from the combustion of said particles to regenerate said first solid compound and said second compound by reverse endothermal reaction of said exothermal reaction. The invention also concerns an exhaust line (1) and a particulate filter (2) for implementing said method.
