    摘要: A device 1, capable of being placed in-line in the exhaust conduit of an IC engine upstream of an SCR catalyst, which produces a gaseous hydrolysis product, containing ammonia, which is added to the exhaust gas in a controlled manner to pass therewith through the SCR catalyst to reduce the NOx content of the exhaust gas. The device 1 has an inlet 2 and an outlet 3 for the exhaust gas flowing therethrough and comprises an outer body 4, which forms a pressure barrier, and passing through the outer body 4 is an inner body 5 which comprises a flowpath longitudinally therethrough from the inlet 2 to the outlet 3. The device 1 is split into two sections, a reactor section with an inlet for pressurised aqueous urea and comprising an upper and lower area connected by a plurality of tubes 10 which pass through the exhaust gas for heat exchange and wherein the hydrolysis of urea occurs at elevated temperature and pressure and a reservoir section connected to the reactor section via a pressure release valve to allow the gaseous hydrolysis product to pass from the reactor to the reservoir. The device further comprises a valve 17 for dosing the gaseous hydrolysis product into the exhaust gas.

    摘要: A thermo-hydrolysis reactor (1) for producing ammonia-containing gas by heating an aqueous solution of urea is described. The reactor (1) comprises an elongate vessel (2) having a middle tubular section, an enlarged lower section (4) having an inlet (5) for the urea solution, and an enlarged upper section (3) having an outlet (6) therein for the ammonia-containing gas. The reactor (1) is adapted such that, in use, heat transmitted through the walls of the reactor (1) from an external heat source heats the urea solution causing it to hydrolyse producing the ammonia-containing gas.
