SCR denitrification catalysts are catalytic materials that promote the selective catalytic reduction of nitrogen oxides (NOx) in flue gas with reducing agents at appropriate temperatures. They are widely used in flue gas denitrification systems across thermal power generation, steel, biomass power, waste incineration, cement, and coking industries. By structural form, SCR denitrification catalysts are primarily classified into plate-type and honeycomb-type categories.
At present, the application of SCR denitrification catalysts is expanding from traditional thermal power scenarios to non-power sectors such as steel, cement, waste incineration, and biomass power generation. Future growth will be driven by the large-scale implementation of ultra-low emission policies in the cement industry, steady replacement demand for existing catalysts in steel applications, and the accelerating trend toward integrated CO oxidation and SCR denitrification catalyst synergistic treatment. Overall, the deepening implementation of ultra-low emission policies across multiple industries and structural transformation of application scenarios serve as the core drivers for the sustained growth of China's SCR denitrification catalyst market.
The total market size of China's SCR denitrification catalysts grew from RMB 6.31 billion in 2021 to a projected RMB 150.2 billion by 2030, achieving more than a twofold increase. Among them, the thermal power segment grew steadily from RMB 4.65 billion in 2021 to RMB 5.41 billion in 2030; the steel segment surged from RMB 710 million in 2021 to RMB 2.87 billion in 2025, at a CAGR of 41.6%; and the cement segment leapt from RMB 660 million in 2024 to RMB 1.52 billion in 2025, a growth rate of 51.7%, emerging as the industry's core incremental growth segment.
