Heavy-Duty Vehicles

Emissions from diesel engines are of increasing concern to government regulators around the world. Cars, trucks and off-road equipment that run on diesel fuel are the source of harmful hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM) that pollute the air and are linked to respiratory diseases.

We are a leading supplier of cost-efficient, effective diesel-emission-control technologies.

These technologies are in use today on most of the diesel vehicles produced around the world. BASF maintains significant diesel research and development facilities around the world. These facilities are being used to develop the technologies needed to meet the extremely low emission levels called for in new emissions regulations.

Emissions Control Catalysts Brochure

As the global leader in catalysis, BASF has unsurpassed expertise in developing innovative emission control technologies for a wide range of applications, to enable clean air for a sustainable future. Check out all of our solutions below.

Our Innovative Solutions

Compliance to strict emission limits, such as Euro 6, is a challenge for the emission system. The pollutants carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) need to be reduced as well as soot (PM). Our mission is to deliver cost-effective solutions for these increasingly stringent emissions control regulations.

Diesel Oxidation Catalysts (DOC)

BASF's Diesel Oxidation Catalyst (DOC) technology controls emissions of hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) from diesel vehicles.

It was the first catalytic emissions control system to meet U.S. Environmental Protection Agency (EPA) certification requirements for the U.S. Urban Bus Retrofit Program, and offers many benefits:

Can reduce HC and CO emissions by 50% or more

Integrated, easy-to-install bolt-on technology

Fuel sulfur tolerance

Easy maintenance; needs no additional parts or sensors

U.S. EPA approved for two- and four-stroke diesel engines

BASF DOCs have millions of miles of proven performance in light duty passenger car, urban bus, medium duty truck and heavy duty truck applications. BASF DOC technology platforms and precise patented manufacturing process enable BASF to provide DOC technologies that light off at very low temperatures using a minimum amount of precious metal. The catalysts are also currently in use on tens of thousands of retrofitted vehicles around the world.

Selective Catalytic Reduction (SCR)

BASF Catalysts technologies enable customers to meet tightening NOx emission standards around the world. BASF Catalysts has been a leader in SCR technology for stationary source emissions.

Building on that expertise and experience, BASF Catalysts has SCR technologies to meet NOx mobile emissions regulations around the globe. In addition to traditional vanadium based technologies, we have patented zeolite SCR catalysts that offer very high temperature stability and operating temperature flexibility.

As lower emission standards drive the requirement for active filter systems in conjunction with NOx reduction technologies, the high temperature stability of BASF Catalysts's zeolite SCR catalysts help customers meet challenging catalyst durability requirements.

Selective Catalytic Reduction on Filter (SCRoF)

SCR on Filter controls NOx (nitrogen oxides) and PM (particulate matter or soot) emissions from diesel engines, on a single substrate.

This technology combines two components into one:

SCR (Selective Catalytic Reduction) which reduces NOx to nitrogen and water in the presence of a reductant, such as AdBlue® by BASF, a high purity urea solution

DPF (Diesel Particulate Filter) which filters the PM

The advantages of BASF’s SCR on Filter technology include:

BASF’s advanced zeolite SCR technology has superior durability to better withstand active filter regeneration

SCRoFperformance similar to SCR and DPF performance on separate components

Elimination of a substrate can save space and weight

Ammonia Oxidation Catalysts (AMOx)

BASF’s patented AMOX ammonia oxidation catalysts are designed to prevent ammonia breakthrough or slip in SCR (Selective Catalytic Reduction) systems. This prevents ammonia from reaching the atmosphere.

The AMOX catalyst coating can be zoned onto the SCR substrate. It can also be put on a separate substrate. This provides greater flexibility for the system design.


Catalyzed Soot Filters (CSF)

BASF's Catalyzed Soot Filters (CSF) (also called diesel particulate filters or DPF) are designed to reduce emissions of particulate matter (PM) from diesel engines. The filters first trap particulates and then use a patented catalytic technology to continuously burn them at normal diesel operating exhaust temperatures.

Benefits:

BASF Catalysts | Catalytic Converter

Able to trap very fine particles including those below one tenth of a micron which includes most of the PM10

Can reduce particulate matter, carbon monoxide and hydrocarbons by 90+%

Multi-functional Catalyzed Soot Filters

The CS4F (multi-functional catalyzed soot filter) with a LNT is a solution to meet strict Euro6 emission regulations. Compared to a LNT+CSF+UF-SCR (Under Floor Selective Catalytic Reduction) system, the LNT+CS4F system can eliminate one catalytic component, resulting in lower system weight, space and complexity.

The combination of newly developed materials, high utilization of precious metals and precise processes to apply such materials led to this improved LNT technology for Euro6 legislation. In addition, the development of the new CS4F multi-functional catalyzed soot filter was required to further enhance the operational window for such an advanced emissions reduction system for diesel passenger car applications.

The LNT+CS4F system offers significant value to automakers.

Lower weight

Saves space

Less complexity

Retrofit

Emissions from diesel engines are of increasing concern to government regulators around the world. Buses, trucks, mining vehicles, power generators and other diesel-based equipment are the source of harmful hydrocarbons, nitrogen oxides (NOx) and particulate matter (PM) that pollute the air and are linked to respiratory diseases.

Regulations on new vehicles are important, but since diesel engines can last 20-30 years, emissions from older diesel engines must be addressed as well. That’s where BASF’s retrofitting technologies come in.

BASF is a leading supplier of cost-efficient diesel-emission-control technologies for the retrofit market, including Diesel Oxidation Catalysts and Diesel Particulate Filters, which are in use today on thousands of trucks and buses around the world.

Heavy Duty Diesel

Heavy duty diesel on-road and offroad vehicles and equipment present unique challenges for emissions control. There are two general system approaches: active and passive. In an active system, fuel is periodically injected into and combusted over the DOC to raise the temperature of the exhaust gas and burn off the soot in the filter. In a passive system, the DOC is formulated to generate NO2 which is used to continuously remove soot from the filter.

Natural Gas Catalyst

Although gasoline and diesel fuels dominate the landscape today, there is growing interest in alternative fuels, especially natural gas to power vehicles. While alternative fuels often burn cleaner than gasoline or diesel fuel, they nonetheless produce emissions such as carbon monoxide (CO), nitrogen oxides (NOx) and hydrocarbons (HC). Proven solutions. For over a decade, BASF has offered the leading catalyst technology for natural gas vehicles (NGVs). We have solutions to meet strict emission regulations including Euro IV-VI, US2010 and Global Tier 4, and cover a broad range of natural gas engines.
