摘要： A process for removing nitrogen oxides from a combustion gas stream which process comprises:
(a) heating an aqueous solution of urea, or a mixture of urea, containing biuret or ammonium carbamate on site, in a hydrolysis reactor such that a gaseous ammonia-containing product is obtained which is essentially free of urea, biuret, or ammonium carbamate, the temperature and pressure being maintained by the input of heat to the reactor;
(b) separating the gaseous ammonia-containing product from the liquid phase aqueous reaction media at the operating pressure;
(c) retaining the liquid phase reaction medium in the reactor for further conversion to gaseous ammonia and carbon dioxide, and/or recycling at least a portion of the said reaction medium back into the reactor, a urea dissolver, or the feed solution to the reactor for further conversion;
(d) withdrawing the gaseous ammonia and carbon dioxide-containing product separated in step (b) at a controlled rate; and
(e) contacting the gaseous ammonia-containing product with the combustion gas stream at a rate which essentially matches the demand requirement of nitrogen oxides removal in said combustion gas stream;
characterised in that the temperature in the hydrolysis reactor is not controlled but is allowed to vary to match the demand requirement for ammonia and in which the pressure is varied as function of the demand requirement for ammonia or reactor operating temperature.

摘要： SCR method for_purifying the exhaust gases of an internal combustion engine of a vehicle, according to which ammonia gas is exclusively metered in the exhaust gases, the method comprising a step of releasing ammonia gas from at least one solid absorbing matrix where it is stored by sorption and a step of metering the released ammonia gas in the exhaust gases. The method is such that it comprises a step of regenerating the solid absorbing matrix that consists in:
- generating a refilling ammonia gas by chemically decomposing a ammonia precursor in a biochemical decomposition unit (3) mounted on board the vehicle and storing at least one protein component adapted to decompose said ammonia precursor;
- directing the refilling ammonia gas to the solid absorbing matrix where it is stored thereon.

摘要： SCR method for the exhaust gases of an internal combustion engine, according to which:
- an ammonia precursor is stored in a storage tank (1)
- part of this precursor is thermally decomposed either directly prior to or while being metered into the exhaust gases
- at least intermittently and parallel to or in alternation therewith, ammonia released from a solid storage medium where it is stored by sorption is also metered in the exhaust gases, said ammonia having been generated by thermally decomposing a stream of the stored ammonia precursor in a heater (3), wherein no fluid is returned from the heater to the storage tank and wherein:
- either the thermal decomposition of the ammonia precursor generates no water
- or the thermal decomposition of the ammonia precursor generates water which is separated from the ammonia and collected.
