TopFrax™ catalytic ceramic filter

TopFrax™ is a patent-pending catalyst-coated ceramic filter designed to treat off-gasses in high-dust environments found in a wide range of industries and activities.

How TopFrax™ works

The TopFrax™ filter is based on a ceramic fiber impregnated with a particular catalytic solution. The chemical composition is made to suit the specific needs of the different customers. A combination of dust, NOX, NH₃, dioxins, CO and different VOCs can be removed in one single step. The catalyst is loaded uniformly along a well-defined fraction of the wall providing the lowest cost of compliance and ensuring undesirable reactions (e.g. SO₂ oxidation).
In addition to their multi-compound capabilities, TopFrax™ ceramic catalytic filters are effective at temperatures as high as 400°C. Combined, these advantages can help you reduce capital expenditures by up to 40% compared to competing solutions.

Broad spectrum of regulated pollutants

Built on decades of leadership in filtration and catalysis, TopFrax™ can transform the economics of meeting regulatory emissions standards, removing dust and multiple gaseous compounds in one single step.

Dust

TopFrax™ effectively blocks particulates and dust particles at the filter surface the same way conventional filters do, ensuring full compliance with stringent emission standards.

TopFrax™ candles are made from either refractory ceramics or fibers with low bio-persistence. Both products trap dust emissions (below PM 2.5) down to 2 mg/Nm³.

NOx

TopFrax™ use selective catalytic reduction (SCR) to remove NOx from off-gas, by utilizing ammonia to convert to harmless nitrogen and water.

VOCs

The catalyst sites on TopFrax™ filters also oxidize CO and volatile organic compounds into harmless CO₂ and H₂O.
The TopFrax™ oxidation version ensures optimal combustion of VOCs with no additional emission of CO.

Dioxins

TopFrax™ also ensures compliance with limits on dioxins and furans, by treating more than 99% of these by converting them into harmless compounds and reducing their concentrations to below 0.1 ng/Nm³, TEQ.

Sustainable Aviation Fuel

As a direct replacement for conventional fuel, SAF is an easy decarbonization measure that will help the aviation industry decarbonize immediately.

Power-to-X

To lower emissions in energy-intensive industries and long-distance transportation, we need technologies such as electrolysis in Power-to-X processes technology.

Renewable fuels

Renewable fuels will help us decarbonize heavy-duty transportation, and we’ll need proven technologies for their production. Luckily, these already exist.

Hydrogen

The abundance of hydrogen coupled with its potential for sustainable methods of production, positions it as a promising solution in the global energy transition. 

Ammonia

Ammonia is considered a gamechanger in decarbonizing the maritime industry and other energy-intensive industries where direct electrification is not an option.
