Selective catalytic reduction (SCR) and its effects
Under emissions standards, engine manufacturers must reduce certain engine emissions, including Nitrogen Oxides (NOx). One available way to reduce nitrogen oxide emissions is Selective Catalytic Reduction (SCR), which is already used in many of our engines.
As emissions regulations become more stringent, engine manufacturers are looking for the most efficient and affordable way to control emissions from exhaust systems.
Eu Stage IV/ US EPA Tier 4 Final emissions standards require significant reductions in nitrogen oxide (NOx) emissions from diesel engines.
To this end, manufacturers have adopted a number of technologies to reduce the emission of these pollutants. Selective catalytic reduction (SCR), one of our core technologies for 854F, 1204F and 1206F engines, helps us achieve this.
This is a proven and advanced system that significantly reduces pollutant emissions.
What is SCR?
If you are looking for a solution to reduce nitrogen oxide, SCR may be a suitable choice. SCR is a catalytic chemical reaction that reduces nitrogen oxide to water and nitrogen.
The process uses Diesel Exhaust Fluid (DEF) as a reducing agent. DEF is sprayed into the pipe, where it mixes with the exhaust gas. The DEF/ exhaust mixture reacts as it passes through the SCR catalyst.
Fe-beta molecular sieves were prepared by ion exchange method under different preparation conditions, and the effects of different preparation conditions on the catalyst active site and NH3- were investigated
The influence of SCR activity. By UV-Vis analysis, the absorption peaks at different locations were attributed to different iron active sites, and the high energy spectrum region below 300 nm could be used
It belongs to the isolated Fe3+ site, the oligomerized FexOy cluster between 300 and 400 nm, and the large particle Fe2O3 polymer above 400 nm. In contrast to
The SCR activity of the catalyst showed that isolated Fe3+ and oligomerized Fe3+ were the main active sites, and the proportion of these two species was directly influenced
The large-scale Fe2O3 is the inactive site, and its proportion should be controlled and reduced as much as possible. In addition, the proportion of Fe3+ in oligomerization state
The higher the case, the higher the N2O production and the worse the selectivity of N2. Therefore, in the preparation process, in addition to controlling the large-scale Fe2O3 content, it is necessary to try
Reduce the content of Fe3+ in the oligomerization state to increase the selectivity of N2. Fe-beta catalyst was prepared by ion exchange method, pH, exchange temperature, precursor type,
Preparation conditions such as Si-Al ratio and calcination conditions will affect the active site of Fe-beta, resulting in differences in activity. Adjust and control according to actual application requirements
The distribution of active species can be controlled effectively, and the iron-based molecular sieve catalyst with high NH3-SCR activity can be prepared.
Advantages of Fe-beta molecular sieve
Selective catalytic reduction of NH3 in diesel vehicle reprocessing technology
NOx technology (NH3-SCR) is the most effective NOx emission control
Hand segment [1-3]. The commonly used NH3-SCR aftertreatment accelerator includes vanadium
Base -SCR catalyst, iron - zeolite -SCR catalyst and copper - based component
Subsifter-scr catalyst [4]. Among them, the iron-base SCR catalyst has a
It has better SCR activity, excellent high temperature performance and anti-sulfur activity,
And got a lot of attention
