2032 年选择性催化还原市场预测:按还原剂类型、催化剂类型、成分、应用、最终用户和地区进行的全球分析Selective Catalytic Reduction Market Forecasts to 2032 - Global Analysis By Reducing Agent Type (Ammonia, Urea and Diesel Exhaust Fluid), Catalyst Type, Component, Application, End User and By Geography |
根据 Stratistics MRC 的数据,全球选择性催化还原市场预计在 2025 年达到 154 亿美元,到 2032 年将达到 251 亿美元,预测期内的复合年增长率为 7.2%。
选择性催化还原 (SCR) 是一种先进的排放控制技术,在催化剂的作用下,透过与还原剂(通常是氨或尿素)发生化学反应来减少废气中的氮氧化物 (NOx)。该过程将有害的 NOx排放转化为无害的氮气 (N2) 和水蒸气 (H2O),显着降低空气污染水平。 SCR 广泛应用于发电厂、工业锅炉和柴油发动机,可更好地满足欧盟 6 和 Tier 4 标准等严格的环境法规的要求。
根据国际清洁交通理事会(ICCT)的数据,欧盟6d标准要求柴油乘用车的NOx排放低于80mg/km,而国六标准则将轻型车的NOx排放限制在35mg/km。
工业化和发电的扩张
全球工业化加速和发电活动不断成长是选择性催化还原 (SCR) 市场的重要驱动力,尤其是在新兴经济体。中国国六标准和印度BS-VI等严格的排放标准要求燃煤发电厂和重工业减少氮氧化物排放,从而推动了SCR技术的应用。 SCR 技术与热电联产 (CHP) 系统的整合进一步推动了全球空气品质法规的遵守并加速了市场渗透。
尿素供应依赖度(DEF)
尿素是 SCR 系统的关键成分,用于生产氨以减少柴油引擎中的氮氧化物。由于供应链中断或地缘政治因素导致尿素供应波动,可能导致成本增加和营运效率低。此外,某些地区对尿素进口的依赖加剧了其对市场波动的脆弱性。因此,尿素供应有限可能会阻碍 SCR 技术的采用并影响严格的排放法规的遵守。
扩大在海洋和航空领域的应用
国际海事组织 Tier III 标准等严格的排放法规正在推动采用 SCR 系统来减少船舶的氮氧化物 (NOx)排放。同样,在航空领域,人们正在研究 SCR 技术以满足地面支援设备和辅助动力装置的环境标准。这些应用正在推动 SCR 催化剂、轻量化设计和空间受限环境中的小型化系统的进步。
来自替代排放控制技术的竞争
废气再循环(EGR)和稀油氮氧化物捕集器(LNT)等新技术为减少氮氧化物排放提供了经济高效的解决方案。这些替代技术在某些应用方面可能优于 SCR 系统,导致 SCR 技术的采用减少。此外,混合动力汽车和电动车技术的进步将进一步减少对 SCR 系统的需求,因为这些汽车的排放气体较低。
疫情最初扰乱了 SCR 供应链,在封锁期间推迟了零件製造和安装计划。工业活动的下降和排放气体法规的延迟导致2020-2021年需求暂时放缓。然而,欧盟绿色新政和美国基础设施法案等疫情后復苏计画已优先为清洁空气技术提供资金,并恢復了对 SCR 的投资。由于需求强劲和监管收紧加速,SCR 市场目前正在復苏。
钒基催化剂市场预计将成为预测期内最大的市场
由于钒基催化剂在减少氮氧化物 (NOx)排放方面效率高,预计在预测期内将占据最大的市场占有率。 TiO2 上负载的 V2O5 催化剂可在很宽的温度范围内有效运行,适用于各种工业应用。即使在低温下也能实现较高的NOx转换率,这使得它在严格的法规环境中也具有吸引力。然而,对钒毒性和处置挑战的担忧可能会影响市场成长。
预计在预测期内,发电厂部分将以最高的复合年增长率成长。
预计发电厂部门在预测期内将实现最高成长率。 SCR 系统广泛应用于燃煤发电厂和天然气发电厂,以符合旨在减少 NOx排放的严格环境法规。全球能源需求的不断增长和向清洁能源来源的转变进一步推动了 SCR 技术在发电中的应用。此外,向再生能源来源的转变可能会影响发电厂对 SCR 系统的长期需求。
在预测期内,由于工业化进程加快和能源需求不断增加,预计亚太地区将占据最大的市场占有率。主要製造地的位置,加上严格的排放法规,正在刺激所有产业采用 SCR 技术。中国和印度是工业排放最大的国家之一,正在大力投资氮氧化物减排解决方案。该地区运输、发电和石化行业的扩张继续支持市场成长。
在预测期内,由于严格的环境法规和排放控制技术的进步,预计北美将呈现最高的复合年增长率。美国和加拿大有严格的NOx排放标准,迫使工业界采用SCR系统来遵守。人们越来越关注减少发电厂、汽车和海洋工业的温室气体排放,这进一步推动了市场的成长。
According to Stratistics MRC, the Global Selective Catalytic Reduction Market is accounted for $15.4 billion in 2025 and is expected to reach $25.1 billion by 2032 growing at a CAGR of 7.2% during the forecast period. Selective Catalytic Reduction (SCR) is an advanced emission control technology that reduces nitrogen oxides (NOx) from exhaust gases through a chemical reaction with a reductant, typically ammonia or urea, in the presence of a catalyst. This process converts harmful NOx emissions into harmless nitrogen (N2) and water vapor (H2O), significantly lowering air pollution levels. Widely used in power plants, industrial boilers, and diesel engines, SCR enhances compliance with stringent environmental regulations such as Euro 6 and Tier 4 standards.
According to the International Council on Clean Transportation (ICCT), Euro 6d standards require NOx emissions from diesel passenger cars to be below 80 mg/km, while China 6 standards limit NOx emissions to 35 mg/km for light-duty vehicles.
Growing industrialization and power generation
The accelerating pace of industrialization and expanding power generation activities worldwide are pivotal drivers for the selective catalytic reduction (SCR) market, particularly in emerging economies. Stringent emission norms, such as China's National VI and India's BS-VI standards, mandate NOx reduction in coal-fired plants and heavy industries, propelling SCR adoption. The integration of SCR technology in combined heat and power (CHP) systems further supports compliance with global air quality regulations accelerating market penetration.
Dependency on urea supply (DEF)
Urea, a critical component in SCR systems, is used to produce ammonia for NOx reduction in diesel engines. Fluctuations in urea availability due to supply chain disruptions or geopolitical factors can lead to increased costs and operational inefficiencies. Additionally, reliance on urea imports in certain regions exacerbates vulnerability to market volatility. Thus limited urea supply can hinder the adoption of SCR technology, impacting compliance with stringent emission regulations.
Expanding use in marine and aviation sectors
Stringent emission regulations, such as IMO Tier III standards, are propelling the adoption of SCR systems to reduce nitrogen oxide (NOx) emissions from ships. Similarly, in aviation, SCR technology is being explored to meet evolving environmental standards for ground support equipment and auxiliary power units. These applications are fostering advancements in SCR catalysts, lightweight designs, and compact systems tailored for space-constrained environments.
Competition from alternative emission control technologies
Emerging technologies, such as Exhaust Gas Recirculation (EGR) and Lean NOx Traps (LNT), offer cost-effective and efficient solutions for reducing nitrogen oxide emissions. These alternatives can outperform SCR systems in specific applications, leading to reduced adoption of SCR technology. Additionally, advancements in hybrid and electric vehicle technologies further diminish the demand for SCR systems, as these vehicles produce fewer emissions.
The pandemic initially disrupted SCR supply chains, delaying component manufacturing and installation projects amid lockdowns. Reduced industrial activity and deferred emission compliance timelines temporarily slowed demand in 2020-2021. However, post-pandemic recovery packages, such as the EU's Green Deal and U.S. Infrastructure Bill, prioritized funding for clean air technologies, reviving SCR investments. The market is now rebounding, driven by pent-up demand and accelerated regulatory enforcement.
The vanadium-based catalysts segment is expected to be the largest during the forecast period
The vanadium-based catalysts segment is expected to account for the largest market share during the forecast period due to their high efficiency in reducing nitrogen oxides (NOx) emissions. These catalysts, typically composed of V2O5 supported on TiO2, operate effectively across a wide temperature range, making them suitable for diverse industrial applications. Their ability to achieve high NOx conversion rates, even at low temperatures, enhances their appeal in stringent regulatory environments. However, concerns over vanadium toxicity and disposal challenges may impact market growth.
The power plants segment is expected to have the highest CAGR during the forecast period
Over the forecast period, the power plants segment is predicted to witness the highest growth rate. SCR systems are widely adopted in coal-fired and natural gas-fired power plants to comply with stringent environmental regulations aimed at reducing NOx emissions. The increasing global energy demand and the transition to cleaner energy sources further boost the adoption of SCR technology in power generation. Additionally, the shift towards renewable energy sources may impact the long-term demand for SCR systems in power plants.
During the forecast period, the Asia Pacific region is expected to hold the largest market share due to rapid industrialization and increasing energy demand. The presence of major manufacturing hubs, coupled with stringent emission control regulations, has fueled the adoption of SCR technology across industries. China and India, being among the largest contributors to industrial emissions, are heavily investing in NOx reduction solutions. The expansion of transportation, power generation, and petrochemical sectors in the region continues to support the market's growth.
Over the forecast period, the North America region is anticipated to exhibit the highest CAGR driven by stringent environmental regulations and advancements in emission control technologies. The U.S. and Canada have enforced strict NOx emission standards, compelling industries to adopt SCR systems for compliance. The growing focus on reducing greenhouse gas emissions in power plants, automotive, and marine industries is further accelerating market growth.
