Annual production capacity of 5000+ sets of high-horsepower internal combustion engine exhaust aftertreatment products and systems.
Selective catalytic reduction (SCR) of diesel exhaust NOx control, the use of NH3 or urea (usually used in the mass ratio of 32.5% of the aqueous solution of urea) as a reducing substance, in the O2 concentration is higher than the NOx concentration of more than two orders of magnitude under certain conditions, under certain temperatures and catalysts, the use of NH3 to NOx reduction to N2 and H2O, due to NH3 high Due to the high selectivity of NH3, NOx is preferentially reduced without reacting with O2 first, so it is called "selective catalytic reduction". The excess NH3 is coated with a certain proportion of ammonia escape catalyst (ASC) at the end of the SCR carrier to ensure that the NH3 reacts with O2 to produce N2 and H2O, and to avoid secondary pollution caused by NH3 leakage.
