Catalytic elements provide a continuous on-line corrugating, catalyst coating and honeycomb process, which produces an even coating of catalyst material both axially and around the cell walls. Eliminates uneven coating distribution encountered on many post-coating products. Result is longer life with effective utilization of catalyst materials, while at the same time maintaining wider cell openings to minimize blocking. The herringbone corrugation patterns provide superior emission reduction efficiency with minimal pressure drop. Catalyst features angled channels that create turbulence and a complex gas path that promotes mixing. This provides 45 to 50% higher mass transfer rate than the laminar flow that occurs in narrow parallel channels. Channels are designed to enhance gas mixing, while, at the same time, protect against plugging.

The Oxidation Catalysts provide hydrocarbon and CO abatement with secondary particulate reduction for diesel applications, and CO and Non-Methane Hydrocarbons (NMHC) abatement from lean burn natural gas and LPG Engines. High reduction of aldehydes removes the characteristic objectionable odor of LPG and Diesel exhaust.

The 3-Way Catalyst uses non-selective catalytic reduction (NSCR) to reduce NOX and is designed for rich-burning (fuel rich) gas engines operated at or very close, to a stoichiometric air/fuel ratio. NOX catalytically is reduced to nitrogen while providing oxygen that reacts with Carbon Monoxide (CO), hydrocarbons (CXHX), aldehydes, and poly aromatic hydrocarbons (PAH), oxidizing them to carbon dioxide (CO2) and water vapor (H2O).

3-Way Catalyst Reaction Two Step Process
1. Deplete Oxygen (Oxidize CO with any “free or excess” O2 that may be in the exhaust gas; this must be no more than 0.5% excess air relative to stoichiometric)
2CO + O2 = 2CO2CmHn + (m + n/4)O2 = mCO2 + n/2H2O
2. Convert NOx (NO and NO2 are chemically reduced to Nitrogen (N2) making the oxygen available to chemically oxidize the CO to CO2)
NO + CO = 1/2N2 + CO22NO2 + 4CO = N2 + 4CO2
It should be noted that atoms are recombined (referred to as “conversion”) from emission molecules to harmless byproducts. The amount of conversion is commonly reported as reduction (percent) for internal combustion engine catalysts. The term “destruction” is also used instead of reduction, but nothing is really destroyed.

OXIDATION APPLICATION Silencers incorporate a passive system utilizing oxidation catalyst element to provide HC, Aldehyde and CO abatement with visible smokeand exhaust odor reduction for diesel, lean burn natural gas and LPGEngines. THREE WAY APPLICATION Silencers incorporate a passive system utilizing non-selective catalytic reduction (NSCR) to reduce NOX and oxidize CO and HC from rich-burning (fuel rich) gas engines operated at or very close to astoichiometric air/fuel ratio. For optimum performance, engines must beequipped with an air/fuel ratio controller. NOX catalytically is reduced tonitrogen while providing oxygen that reacts with Carbon Monoxide (CO) and hydrocarbons (CXHX), oxidizing them to carbon dioxide (CO2) and water vapor (H2O). Typical attenuation : 6100 Series: 30 to 38 dB’A’
CONSTRUCTION All welded heavy-duty carbon steel body. Inlets and Outlets arestandard with 125/150# ANSI Flanges. Optional fittings are availableupon request.
Available in Stainless Steel. Consult factory for additional materialoptions.

Diesel Particulate Filters GT Exhaust Systems, Inc. (Catalyzed Soot Filters) Lincoln, Nebraska
Diesel particulate matter (soot) is composed of solid as well as liquid. Particulates consist of liquid heavy hydrocarbon, carbon soot, water, and hydrated sulfuric acid. Carbon monoxide (CO), a poisonous gas produced by incomplete combustion, is created when fuel is burned. Incomplete burning results in hydrocarbon emissions (HC).

% Emission Reduction
Diesel emissions account for approximately 70% of all particulate matter contaminating our air, and is now classified as a toxic air contaminant by the California Air Resources Board. The longevity associated with Diesel engines will require retrofits in order to achieve ambient air pollution reductions. GT Silencers utilizes catalyzed particulate filters to dramatically reduce Diesel emissions. The advanced technology behind the catalyzed Diesel particulate filters help engines to comply with governmental emissions regulations by reducing toxic levels of Diesel particulate matter, carbon monoxide and hydrocarbons. The filter consists of a cellular ceramic substrate. Exhaust gases enter a honeycombed maze of channels that actually captures the particulates. The filter is designed to be self-regenerating. The special catalytic coatings on the filter substrate interact with the gases and carbon particles to create complex chemical reactions. The interaction between the exhaust gas and the filter creates a chemical reaction, which converts carbon monoxide and hydrocarbons into harmless carbon dioxide and water vapors. Virtually all particles larger than 35 nanometers are efficiently removed from the exhaust. Tests have shown that up to 95% of the DPM is removed. Hydrocarbons and carbon monoxide are also reduced by up to 95%.
The regeneration process is dependent on exhaust temperatures. High sulfur fuels (greater than 15 ppm sulfur content) require a minimum exhaust temperature of 375 to 390 C (approx 700 to 735 F). Ultra low sulfur fuels (less than 15 ppm sulfur content) require a minimum temperature range of 340 to 350 C (approx 645 to 665 F). GT Exhaust Systems catalyzed Diesel particulate filter silencer features a special thermal wall inserted between the double shells. This construction is modified to prevent any fiberglass from escaping into to exhaust systems or filters. The thermal wall aids in capturing and retaining the exhaust temperature while the gases pass through the silencer, allowing for optimal regeneration and performance of the catalyzed Diesel particulate filters.

Diesel Particulate Filters GT Exhaust Systems, Inc. (Catalyzed Soot Filters) Lincoln, Nebraska
Test results of GT Exhaust filters incorporated in a GT Exhaust Silencer To meet the 85% particulate reduction requirement of the California Air Resources Board (CARB) and the local AQMD, GT Exhaust filters incorporated inside a GT Exhaust critical grade, low profile silencer were installed on a MY2000 Caterpillar 3516B, 2 megawatt generator set operating on ultra low sulfur diesel fuel. Emissions source testing was performed on the generator set. Gaseous analyses for carbon monoxide (CO) and total hydrocarbon (THC) emissions were performed conforming to CARB Method 100 for Stationary Source Testing, and particulate matter (PM) analysis was performed conforming to CARB Method 5 for Stationary Sources. Method 5 is a more encompassing measurement of particulate than the EPA full-dilution method, as liquid and gaseous components in the exhaust stream are included in the PM measurement.
GT Silencer and Filter Combination
CAT 3516 2 MW – California generator source testing
The graph illustrates the high reductions for PM, carbon monoxide (CO), and total hydrocarbons (THC). Three different load operations were tested: 50% load, or 1 MW, 75% load or 1.5 MW, and 100% load or 2MW. Results from each load are presented along with the weighted ISO8178 average. The average reduction for PM is 85%, CO and THC reductions are extremely high, >95% and >90%, respectively. These high reductions confirm those obtained by other 3rd party testing on GT Exhaust System products, such as at the Southwest Research Institute in San Antonio, TX and the Motor Test Center in Sweden.
