The hydrodesulphurization catalyst market consists of two variable segments: catalyst material and application that drive refining performances alongside specifying input feed compatibility and operational performance outputs. The sulphur processing catalyst industry selects from different materials such as cobalt-molybdenum (CoMo), nickel-molybdenum (NiMo) and more adapted to handle varying operating pressures and sulphur concentrations.
The demand for diesel desulfurization drives the market because restrictions on low-sulphur fuel regulations. This market serves diesel along with naphtha and jet fuel and various other distillates. The refinery sector now operates advanced catalysts which combine efficiency with cost-effectiveness to satisfy environmental requirements for the treatment of complex crude mixtures.
North America remains a growth driver with refiners upgrading plants and enforcing emission controls. Catalyst technologies for the production of ULSD and enhancement of fuel quality in the USA and Canada.
Sustainable refining and strict sulphur limits are Europe’s priorities. The countries with the most adoption of high-efficiency catalysts to meet Euro VI fuel standards and refinery decarbonization are also Germany, France, and Italy.
Higher demand and capacity expansions position Asia-Pacific as the volume leader. Continuing demand in the region for upgraded HDS catalyst units in refineries.
Stricter Fuel Regulations and Operational Cost Pressures
The hydrodesulphurization (HDS) catalyst industry is obstinately insisting on our ever-stricter global sulphur emissions legislations for fuels. Ultra-low sulphur requirements in regulations such as IMO 2020 and Euro VI mean refiners have to either spend to upgrade or replace their HDS units. The process however operates under high pressure with hydrogen consumption at elevated temperatures causing high energy costs and equipment wear.
Fouling of the catalyst by coke and metal deposits capping the available active sites shortens the lifetime while reducing the efficiency, necessitating more frequent regeneration or replacement. These cost burdens make compliance difficult for smaller refineries unless they make large capital investments in catalytic technology and unit retrofitting.
Cleaner Fuels, Catalyst Innovation, and Demand in Developing Regions
As countries phase out high-sulphur diesel and gasoline, demand for HDS catalysts continues to grow, despite operating challenges. To improve desulfurization at low hydrogen consumption, refineries are introducing advanced surface chemistry of catalyst systems with improved pore structure, larger specific surface area and better dispersion of active metal.
Bimetallic and nanostructured catalysts are rising as promising alternatives, promoting prolonged lifespan and poisoning resistance. Demand from transportation, urbanisation and environmental regulations in Asia-Pacific, Latin America and Africa are spurring new refinery projects and upgrades. As the world transitions away from petroleum-based fuels, HDS catalysts will remain critical for the production of compliant, low-sulphur transportation fuels.
The HDS catalyst market grew at a modest pace between 2020 and 2024, driven by demand for diesel desulfurization and the upgrading of existing refineries to comply with IMO and Euro VI regulations. Conventional cobalt-molybdenum and nickel-molybdenum catalysts continued to dominate, though refiners started to invest in more expensive high-activity alternatives that last longer and reduce downtime.
From 2025 through 2035, the market will transition to more sustainable, energy-efficient catalyst formulations that perform effectively at milder conditions. There will be increasing demand for tailor-made catalysts to cater to the features of the crude and the design of the units. And, as hydrogen management and carbon reduction take centre stage, the integration of HDS catalysts and cleaner hydrogen sources will get more traction.

The hydrodesulphurization (HDS) catalyst market is thriving partly due to tightening global regulations, which aim to limit sulphur emissions from transport fuels. A widely used catalytic chemical process, hydrodesulphurization is a method of removing sulphur from refined petroleum products such as gasoline or jet fuel. Regarding the types of catalysts, cobalt-molybdenum (Co-Mo) catalysts dominate the market as they are efficient under low to moderate-pressure conditions and inexpensive.
Application wise, demand is dominated by diesel hydrodesulphurization, since refineries aim to conform to the ultra-low sulphur diesel (ULSD) specifications, while reducing harmful emissions. Combined, these segments expose a marketplace concentrated on regulatory harmony, environmental performance and the stability of fuelling refinement.
Many governments around the world implement fuel standards, including Euro 6 and Tier 3 regulations, with the aim of decreasing atmospheric sulphur dioxide levels. This trend motivates investment in established catalytic acts such as Co-Mo, and gas into large hydro-desulfurization technology blocks. The HDS catalyst market is key to enabling the energy transition by connecting today’s fuel production with tomorrow’s low-emission approaches as clean energy policies evolve.
| Catalyst Type | Market Share (2025) |
|---|---|
| Co-Mo Catalyst | 51.3% |
Hydrodesulphurization (HDS) processes operated at low-to-moderate hydrogen pressure use Co-Mo (cobalt-molybdenum) catalysts that played a leading role in the type segment owing to their well-established and economical mechanism for sulphur removal.
These catalysts work well on alumina supports and are strongly active for the removal of thiols, sulfide, and other sulphur-compounds from middle distillates. Co-Mo catalysts are also used widely by refineries for the processing of feedstocks such as straight-run gas oils and lighter diesel fractions, yielding optimal performance in this application without the higher price at which nickel-based formulations are priced.
These Co-Mo catalysts have hot operational lifetimes, stability to varied feedstocks, and proven efficacy in diesel and kerosene refining. Catalyst suppliers are also continuing to improve Co-Mo formulations with new pore structures and more surface area for improved activity and selectivity with reduced coking tendencies. Co-Mo catalysts are still the method of choice for cost-effective and scalable sulphur removal, as developing countries add refining capacity and mature markets upgrade to meet emissions mandates.
| Application Type | Market Share (2025) |
|---|---|
| Diesel Hydrodesulphurization | 58.9% |
The application segment in the hydrodesulphurization catalyst market is led by diesel hydrodesulphurization driven by increasing demand for ultra-low sulphur diesel (ULSD) and cleaner-burning transportation fuels. Refineries use hydrodesulphurization catalysts to achieve sulphur content below 15 ppm, a new global standard for most diesel markets.
This reaction needs catalysts that can effectively cleave sulphur bonds, especially those in heavier diesel fractions. With diesel engines still dominant in freight services, agriculture and public transport, environmental compliance is non-negotiable.
In diesel hydrodesulphurization, the challenge for catalyst systems is to achieve higher throughput rates while retaining activity and selectivity over the cycle time. Catalysts that minimize the reduction of certain number, fuel performance, etc., are a high priority for manufacturers. New reactor designs, increased surface-area carriers, and regenerated catalyst options help promote this emerging application.
The stabilizing demand for diesel globally and the tightening green regulations will ensure diesel hydrodesulphurization to continue to dominate the overall market of hydrodesulphurization catalysts owing to its critical importance in emission control while ensuring fuel quality improvement.
The worldwide hydrodesulphurization (HDS) catalyst market provides crucial support in petroleum processing by extracting sulphur from diesel and gasoline as well as jet fuel and other petroleum products. Worldwide emission compliance and ultra-low sulphur fuel production depend on catalysts which mostly consist of cobalt-molybdenum or nickel-molybdenum supported on alumina.
Environmental standards enhanced with cleaner transportation fuel initiatives drive the main market requirements. Global chemical producers who also provide refinery technology lead this market through competitive advantages from their catalyst performance levels combined with operational durability and hydrogen optimization with diverse feedstock processing capabilities.
