Glosfume catalyst elements

Glosfume Ceramic catalyst filters are exceptionally compact allowing them to be utilised in the most restricted of sites.

The Glosfume Catalytic filter element is based on a ceramic fiber impregnated with a bespoke catalytic solution. The chemical composition is made to suit the specific needs of customers operations. A combination of dust, NOx and dioxins, can be removed in one single process. The catalyst is applied evenly within the structure of the ceramic element providing the lowest cost of compliance.

In addition to their multi-compound capabilities, our catalyst filters are effective at temperatures as low as 180°C and as high as 650°C. Combining, these advantages can help reduce capital expenditures by up to 40% compared to alternative solutions whilst minimising the systems footprint.

These elements are designed for industrial operators and engineers requiring reliable high-temperature emission control in demanding processes. They help protect downstream equipment while reducing particulate and catalyst loss, supporting consistent plant performance.

Where catalyst elements fit in a filtration system

Catalyst filtration elements sit within the hot gas filtration stage, positioned after the primary process and before discharge or any downstream equipment. This placement allows them to capture particulates and treat gaseous pollutants in a single step, helping protect downstream catalysts and equipment from fouling while supporting overall emissions control.

They are suited to high-temperature industrial processes, operating effectively between 180°C and 650°C, with ceramic filtration technology capable of withstanding temperatures up to 1000°C. This enables installation directly in the process stream without the need for cooling, maintaining efficiency and continuity.

The ceramic fiber structure, impregnated with a bespoke catalytic material, enables combined filtration and reaction. As gases pass through the element, particulates are retained while the embedded catalyst promotes the breakdown of targeted pollutants.

Designed for industrial processes where temperature and chemical conditions make conventional media impractical, these elements help maintain process continuity by reducing downstream fouling and contamination risk.

How it works

Collection

Within our catalytic filters, the micro-porous elements hang vertically from a header plate. The header plate separates the filter’s clean and dirty compartments. Hot gas is drawn through the filter medium from the outside to the inside. The sub-micron particles are collected on the outer surface, gases then pass through the element contacting the catalyst solution. This increases the rate of reaction removing the harmful gases.

Removal

The sub-micron particles are removed from the element by a powerful, reverse jet pulse. The particles are then discharged through the hopper outlet or directly to a tray for collection and disposal. To improve efficiency and longevity, the filter body is insulated and trace heating options are available.

Process overview

In operation, hot process gas enters the filtration unit and is directed across the ceramic elements. As the stream passes through the ceramic fiber and embedded catalytic material, particulates are captured and targeted gases begin to react. The treated gas then exits the system, while collected material remains on the element surface. At set intervals, reverse-jet cleaning restores performance and prepares the system for continued operation.

Applications

High-temperature waste streams often contain fine particulates alongside complex gaseous pollutants, requiring efficient treatment without excessive system complexity. Glosfume catalyst elements enable combined particulate capture and gas-phase treatment within the filtration stage, helping maintain emissions control while protecting downstream equipment from fouling. This is particularly valuable where operating conditions and waste composition vary over time, requiring stable and predictable performance.

Biomass combustion produces elevated levels of fine particulate matter, including PM10 and PM2.5, often under fluctuating load and fuel quality conditions. Catalyst elements capture these particulates while promoting the breakdown of targeted gaseous compounds within the same unit. This enables efficient operation without extensive gas cooling, resulting in cleaner exhaust streams and more consistent system performance.

High-temperature metal processes generate dust-laden gas streams that can impact downstream equipment and overall process efficiency. Catalyst filtration elements remove particulates and support emissions control, while enabling capture of material that may be recovered where required. This helps reduce contamination risk and protect downstream systems such as heat recovery or secondary treatment stages, contributing to improved reliability and reduced maintenance.

Industrial process streams can present a combination of elevated temperatures, particulate loading, and variable gas composition. Catalyst elements provide combined filtration and catalytic treatment within a single stage, helping maintain control without the need for complex multi-stage systems. This supports consistent operation and reduces the risk of downstream fouling where process continuity is critical.

High-temperature exhaust systems require effective handling of residual particulates and gaseous compounds before discharge. Catalyst elements integrated within the filtration stage capture fine particulates and contribute to further treatment of targeted pollutants. This helps maintain the integrity of downstream equipment and supports cleaner discharge under continuous operating conditions.

Choosing the right element

Selection & specification

Selecting the correct catalyst filtration element requires a clear understanding of process conditions and operational priorities. Each installation is typically configured to suit the specific gas stream, ensuring reliable performance and long service life.
