Selective Catalytic Reduction (SCR) is used to remove nitrogen oxides (NOx) from flue gas released by boilers used in power plants and various combustion sources. In the entire system, the catalyst is considered the most significant component. Selective catalytic reduction (SCR) is a selective inorganic or organic reducing agent utilized to remove the nitrogen oxides (NO, NO2, N2O) with oxygen. The direct emission of such gases is not healthy for the environment.

The SCR denitrification catalyst market is growing daily because of the recent significance of treating industrial chemical waste before its disposal. Everyone is well aware of the fact that nitrogen oxides (NOx), which are emitted by the industrial process of nitric acid or in the exhaust discharge from gasoline engines, are very harmful to the environment. The key players have understood the fact that SCR Denitrification Catalysts can be used more effectively if it will be used to treat harmful nitrogen oxides.

KEY FINDINGS

COVID-19 Impact:

The global COVID-19 pandemic has been unprecedented and staggering, with the SCR denitrification catalyst market experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market's growth and demand returning to pre-pandemic levels once the pandemic is over.

Along with all the industries, even the SCR denitrification catalyst market was negatively impacted. The prime reason behind the negative slopping market is the industry's dependence on chemical manufacturing, oil & gas, automotive, and polymer catalysis, other sectors. Not only is the dependence on other resources the reason for the staggering market, but also several countries restricted trade activities related to SCR denitrification catalyst market. This resulted in reduced usage of catalysts in the various sectors. The demand for the SCR denitrification catalyst was severely affected during COVID-19.  

Latest Trends

USE OF AMMONIA SLIP FOR CHEMICAL REMOVAL OF NITROGEN OXIDE

Inventions aids in the growth process of the industries and one such invention in the SCR denitrification catalyst market is the introduction of ammonia slip. The companies realized that it is necessary to do the selective oxidation of nitrogen oxides to avoid smell and health risks caused by the disposals from the industries. The process included in SCR is that it reduces NOx into simpler forms of molecular nitrogen and water vapor. This chemical process helps in treating waste.

• Over 830 coal-fired boilers across the U.S. have implemented SCR technology to meet nitrogen oxide (NOx) reduction requirements, highlighting a surge in the use of denitrification catalysts for environmental compliance
• Modern SCR catalysts are achieving NOx reduction efficiencies of up to 95%, reflecting a growing trend toward the adoption of next-generation catalyst formulations in industrial and power sectors

• Honeycomb: Honeycomb structures mimic the hexagonal geometry found in nature, offering high strength-to-weight ratios. They're widely used in aerospace and automotive industries for lightweight yet durable components.
• Corrugated: Corrugated materials feature ridges and grooves that boost stiffness and load-bearing capacity. They're frequently seen in packaging and roofing, combining flexibility with structural strength

By Application Analysis

Based on application, the market can be divided into Steel Plants, Cement Plants, Power plants, Chemical industries, and others.

• Steel Plants: Steel plants process raw materials like iron ore into various steel products essential for construction and manufacturing. Their operations involve large-scale furnaces, casting units, and rolling mills.
• Cement Plants: Cement plants grind and heat raw materials like limestone and clay to produce cement, a key binder in concrete. They play a vital role in infrastructure development and urban growth.
• Power Plants: Power plants convert energy from coal, gas, nuclear, or renewables into electricity for homes and industries. They form the backbone of modern civilization by enabling continuous energy supply.
• Chemical Industries: Chemical industries manufacture a wide range of products from fertilizers to pharmaceuticals through controlled chemical processes. They are crucial for agriculture, healthcare, and manufacturing sectors.
• Others: Other industries like textiles, food processing, and paper manufacturing serve everyday consumer needs. Each relies on specialized machinery and processes tailored to their product lines

Driving Factors

USAGE OF CATALYSTS TO AVOID DIRECT EMISSION OF NITROGEN 

Over the last few decades, it has been observed that the direct emission of harmful gases and elements into the environment is an unhealthy practice. Therefore, catalyst research has been focused on SCR denitrification catalyst market to overcome the limitations of direct emission of nitrogen oxides and to minimize side reactions. These work as the SCR denitrification catalyst market growth factor. All industries today are looking for an alternative that causes less harm to the environment and will secure the production process as well. 

• Regulatory programs require large stationary sources to reduce NOx emissions by over 60% from earlier baseline levels, which is directly fueling demand for SCR catalysts as a mandatory control technology.
• Approximately 43% of industrial boilers in regulated sectors have transitioned to SCR-based systems in response to regional NOx control programs, showcasing the expanding application base

AN INCREASING NUMBER OF CHEMICAL INDUSTRIES LEADS TO RISING DEMAND FOR SCR DENITRIFICATION CATALYST

Today, the era is of revolution, which aids economic growth and development. With the growth in the number of industries, it is evident that chemical industries are growing as well. The rising number of chemical industries indicates the increasing pollution caused by the waste disposed directly into the environment. Considering the attention and significance environmental security has gained, chemical industries shifted towards reducing the harmful effects of the direct disposal of nitrogen oxides as well. The use of catalysts lowers the toxicity of the waste disposed of. This in turn resulted in an increase in the demand for SCR Denitrification Catalyst. It is a key factor that is anticipated to offer new opportunities in the global catalyst market. 

Restraining Factors

THE SHUTDOWN OF INDUTRIES DUE TO RISK OF INFECTIONS 

The SCR denitrification catalyst market is incomplete without talking about hydro processing, chemical synthesis, and other applications, which is the root cause of several infections in the workforce. During the COVID- 19 period, when everyone was extra careful regarding their health, the SCR denitrification catalyst market temporarily faced hampered demand. The aware public who does not want to take risk when it comes to their health indicates restricted market.

• Ammonia slip rates in poorly optimized SCR systems can exceed 10 ppm, leading to downstream corrosion and health hazards, discouraging adoption in small-scale industries.
• Conventional SCR catalysts require operating temperatures of 300°C to 400°C, making them unsuitable for low-temperature processes and increasing energy costs.
