Manufactured by:Johnson Matthey Stationary Emissions Control based inHuntington Beach, CALIFORNIA (USA)
Johnson Matthey oxidation catalysts are used to prevent air pollution from almost all industrial and combustion ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
A Three Way Filter (TWF®) is a gasoline particulate filter (GPF) with a JM catalyst coating. Gasoline vehicles fitted with Johnson Matthey TWF technology can reduce particle numbers by up to ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
Hydrocarbon-SCR (lean NOx reduction) systems use hydrocarbons as the reductant. The hydrocarbon may be that occurring in the exhaust gas ('native') or it may be added to the exhaust gas. This has the advantage that no additional reductant source (e.g. urea) need be carried but these systems cannot offer the performance of ammonia-SCR ...

NOx can be removed from a lean gas stream by chemical adsorption onto a catalyst, hence the term NOx adsorber catalyst (NAC). The process of adsorption releases ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
Gasoline fuelled vehicles utilise a three-way catalyst that can reduce carbon monoxide (CO), hydrocarbon (HC) and oxides of nitrogen (NOx) emissions by over 99% – if the air-to-fuel ratio (AFR) is accurately controlled. Optimised conversion is achieved with an AFR of 14.7:1. ...

Johnson Matthey’s SINOx® extruded honeycomb SCR catalysts achieve maximum NOx reduction to control air pollution from industries and combustion sources worldwide. Johnson Matthey is a world leader in catalytic emission control and has manufactured extruded SINOx SCR catalysts since 1987 to control air pollution from industries and combustion sources worldwide. Our homogeneous extruded ...

Johnson Matthey’s NSC technology removes NOX from a lean gas stream and converts it to N2. NOX is adsorbed (lean) and then reduced (rich) → N2. The NSC can be regenerated thermally or under a rich condition. During lean operation, the NSC can also oxidise carbon monoxide (CO) and hydrocarbons (HC) in a similar fashion to that of a diesel oxidation catalyst (DOC). Composition: ...

Johnson Matthey's HAPGuard temperature and pressure monitor ensures that your catalytic converter remains in compliance with RICE NESHAP for clean air. The U.S. Environmental Protection Agency recently implemented clean air regulations to reduce exhaust emissions of hazardous air pollutants (HAPS) from previously unregulated reciprocating internal combustion engines (RICE). Johnson Matthey ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
In most gas streams, carbon monoxide (CO) and hydrocarbons (HC) can be removed by combination with oxygen (O2) using an oxidation catalyst (also known as a 2-way catalyst): CO + ½ O2 → CO2, [HC] + O2 → CO2 + H2O. This reaction is suitable for oxygen-rich (“lean”) gas streams, typical of diesel exhaust and many industrial process emissions. Many diesel particulate ...

Remove over 99% of particulate matter. Have high performance at low precious metal loadings and low back pressure. Are optimised for specific systems and are durable against temperatures and poisons. Oxidise NO to provide favourable NO:NO2 ratios for passive filter regeneration and for downstream catalyst reactions. Can be coated onto a range of different filter substrate ...

Johnson Matthey’s system offers cost-effective, low-temperature oxidation of methane from active and abandoned coal mines. Methane has a global warming potential of up to 25 times that of carbon dioxide. Despite the low concentrations of methane in ventilation air from coal mines, the flow rates are enormous, resulting in significant greenhouse gas emission and global warming impact. ...

Johnson Matthey’s ASC technology removes residual ammonia (NH3) from upstream ammonia dosing systems, converting it into nitrogen (N2) and water ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
Johnson Matthey’s SCRF system integrates selective catalytic reduction (SCR) technology coated on a diesel particulate filter (DPF). SCRF plays a key role in modern diesel after-treatment systems to control both oxides of nitrogen (NOx) and particulate matter (PM) ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
Selective catalytic reduction (SCR) systems work by chemically reducing NOx (NO and NO2) to nitrogen (N2). Johnson Matthey offers coated and extruded ...

Johnson Matthey recognises that today’s chemical industry can be fast moving and highly tailored to customer demands. We deliver this service through our custom catalyst ...
Manufactured by:Johnson Matthey based inClitheroe, UNITED KINGDOM
Johnson Matthey’s diesel oxidation catalyst (DOC) technology can cut CO and HC emissions by more than 90%. Our DOCs are designed to oxidise pollutants in light and heavy duty engines. Carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NO) are oxidised to carbon dioxide (CO2), water (H2O) and nitrogen dioxide ...
