Segmentation by Product Type

The Environmental (Mobile Emission) Catalyst market can be divided into three key product categories, each tailored to specific emission reduction needs in mobile sources.

1. Burning Catalyst

Burning catalysts, also known as oxidation catalysts, are primarily used to convert carbon monoxide (CO) and unburned hydrocarbons (HC) into carbon dioxide (CO2) and water (H2O). These catalysts typically employ platinum and palladium on a ceramic or metallic substrate, offering high efficiency in low-temperature oxidation processes. Their design ensures durability under the harsh conditions of exhaust streams, making them a foundational element in three-way catalytic converters.

• Market Insight: Burning catalysts remain a cornerstone of the market, accounting for a significant share due to their widespread use in gasoline engines. They are especially prevalent in light-duty vehicles where quick light-off times are crucial for meeting urban driving cycle standards. However, fluctuating PGM prices pose challenges, prompting manufacturers to optimize loading and substrate designs for cost efficiency.

• Trend: With the phase-out of older vehicles in developed markets, demand is shifting toward advanced formulations that integrate with gasoline particulate filters, enhancing overall emission control in Euro 6d and beyond compliant systems.

2. Nitrogen Oxide Purification Catalyst

Nitrogen oxide (NOx) purification catalysts, often based on selective catalytic reduction (SCR) technology, utilize urea or ammonia to reduce NOx to nitrogen and water. These systems are critical for diesel engines, employing zeolites and base metals like vanadium or copper to achieve high conversion rates. Their integration with diesel oxidation catalysts creates comprehensive aftertreatment solutions for heavy-duty applications.

• Market Insight: This segment is experiencing robust growth, driven by diesel engine mandates in commercial fleets. NOx catalysts are indispensable for compliance with BS-VI in India and CARB standards in California, where real-world driving emissions testing is enforced. The market benefits from economies of scale as production ramps up in Asia.

• Trend: Innovations in cold-start performance and sulfur tolerance are key, as regulators target NOx reductions in urban environments. Hybrid SCR systems combining with lean NOx traps are emerging for future light-duty diesel vehicles.

3. Automobile Exhaust Catalyst

Automobile exhaust catalysts encompass three-way catalysts (TWC) that simultaneously handle CO, HC, and NOx in stoichiometric gasoline engines. Composed of multi-layered washcoats with PGMs and oxygen storage materials like ceria-zirconia, they operate efficiently near the air-fuel ratio lambda of 1, providing balanced emission control across a wide range of operating conditions.

• Market Insight: As the dominant product segment, automobile exhaust catalysts lead due to the sheer volume of passenger cars globally. They are integral to OEM exhaust systems, with demand surging in emerging markets like India and Southeast Asia as vehicle parc grows. Recycling initiatives are also boosting sustainability by recovering PGMs.

• Trend: The rise of turbocharged downsized engines requires catalysts with enhanced thermal stability and poisoning resistance, leading to investments in intelligent catalyst designs that adapt to varying fuel qualities.

In summary, the product type segmentation highlights the interplay between regulatory needs and technological advancements. Burning and exhaust catalysts dominate gasoline applications, while NOx purification drives diesel growth, collectively propelling the market forward.
