Background Art
The automobile exhaust emissions can cause serious pollution of the atmosphere, the main pollutants of hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and particulate matter (PM). Since the 20 century 70 age people began efforts to control automobile exhaust emissions since, has developed increasingly stringent emission regulations. For the implementation of the "people's Republic of China of atmospheric pollution", strict control on motor vehicle pollution, the full implementation of the "light automobile emission limit value and the measurement method (China's five stage)" (GB18352.5 - 2013) and "vehicle compression ignition, gas fuel spark-ignition engine and automobile exhaust pollutant emission limits and measuring method (China III, IV, V phase)" (GB17691 - 2005) in the standard requirements of the 5th stage discharge, from National self-1 January 2017, all manufacturing, import, sales and registration of the light petrol vehicles, heavy-duty diesel vehicles (passenger car and bus, sanitation, postal use), shall be conforms to the five standard requirements. Therefore, the automobile exhaust gas purifying technology provides greater challenges, higher requirements.
SCR (Selective Catalytic Reduction) catalytic reduction technology is the traditional post-processing technology. By adopting the liquid urea of the traditional SCR technology is essentially utilize urea decomposes under the high temperature ammonia, the ammonia as a reducing agent of NOx in the engine exhaust gas in the catalyst and the temperature of the integrated under the action of the reaction, under the conditions of an ideal to produce non-toxic N2 and H2O, thereby achieving the purpose of purification. However, the traditional SCR system for liquid urea reducing agent facing the freezing in winter and heat insulation thawing problems, urea and the exhaust gas temperature under the condition of relatively high, it is easy to form a condensate of hard, further stopping urea reducing agent nozzle or piled in the exhaust pipe, cause the engine exhaust back pressure rises, to reduce the vehicle fuel economy.

The use of metal chloride with ammonia to form coordination compounds of this characteristic, the ammonia gas is fixed down, use of the metal chloride is mainly alkaline earth metal chloride, strontium chloride, calcium chloride, magnesium chloride, and must be auxiliary additive component. Ammonia synthesis of compound material formed as a vehicle-mounted reducing agent ammonia an ammonia, when in use by heating to achieve desorption release the ammonia gas, the ammonia gas with the metal chloride to adsorb and desorb a is a reversible process.
Because the ammonia desorption of heat absorption process is, therefore a need to increase the ammonia storage device in the heat source, in the Patent number CN 102733913 B (double-stage waste heat mode [...] ammonia system) in discloses a backflow of the coolant of the engine waste heat to heat the active chu anhua compound, release leaves the ammonia of the after-treatment system. The Patent number CN 103470347 A (used for producing the ammonia of the equipment) with the introduction of the ammonia generating device, wherein the 2nd 1st heating device and heating device are respectively installed in the main memory and the secondary memory internal and independent operation. The Patent number US2012/0045379 A1 (a uses the vacuum pump from the solid ammonia in the material storage and supply ammonia gas), introduced the method of storing and delivering ammonia, ammonia material for the heating means of the built-in electric heating or external microwave heating or infrared heating. The Patent number CN 104234796 A (in particular for a motor vehicle exhaust system with optimized filling time of ammonia saves the tube) introduced with ammonia derives the channel built-in heating or enclosed heating of the ammonia storage tube.
