METHOD AND DEVICE FOR PROCESSING THE WASTE GAS OF AN INTERNAL COMBUSTION ENGINE

摘要

The device (15) has a reducing agent solution evaporator (16), a hydrolysis catalyst that is connected to the reducing agent solution evaporator for hydrolysing. A selective catalytic reduction catalyst (18) for selective catalytic reduction of nitrogen oxides. An aqueous solution has a reducing agent precursor that is evaporated by the evaporator unit. The reducing agent solution precursor and a hydrolysis catalyst (17) are mounted and connected to a waste gas line (14). A connecting unit (11) is provided that is made from a ceramic material or poly tetra fluoro ethylene. An independent claim is also included for a method for processing the waste gas of an internal combustion engine, which involves producing a reducing agent.
