2014 IFAT: HOK activated lignite – Efficient filter technology for the environmental sector – a global success

Rheinbraun Brennstoff GmbH presents innovative product solutions for waste-gas and water treatment at the 2014 IFAT trade fair

From 05 to 09 May 2014, Rheinbraun Brennstoff GmbH (RBB) will present innovative product solutions for waste-water and waste-gas cleaning that are based on HOK activated carbon produced from Rhenish lignite at the IFAT trade fair in Munich. This activated carbon produced by RWE Power AG, which is used in the capture of pollutants and is marketed worldwide by RBB under the brand name “Activated Lignite HOK”, has special properties that yield an adsorbent and catalyst which is in demand in numerous environmental fields. Typical applications – besides waste-water and drinking-water treatment – include waste-gas and waste-air cleaning in refuse incineration and in the steel industry, where HOK is deployed globally as competitive and highly effective sorbent. Thanks especially to the favourable pore structure and catalytic properties, Activated Lignite HOK has the capacity to retain a large number of pollutants. This applies particularly to the emission-relevant pollutants of organic compounds, such as dioxins and furans, as well as to those of heavy metals, such as mercury.

Carbon activation of the lignite extracted in RWE Power AG’s opencast mines near Cologne takes place in the so-called rotary hearth furnace process which gave Activated Lignite its brand name HOK (German abbreviation for Herdofenkoks = rotary hearth furnace coke). The activated lignite thus produced has the typical pore structure characteristic of HOK which results in high separation efficiency for a multitude of pollutants. The favourable pore structure present in HOK permits easy access to the inner surface area which is decisive, among other things, for the adsorption of compounds such as those of dioxins and furans. The process, which has been optimized on a basis of decades of experience, guarantees a low-priced bulk product at a constant high quality level. At present, some 180,000 tons of activated lignite are produced in compliance with DIN ISO 9001 per year.

Interested trade visitors are welcome to visit representatives of Rheinbraun Brennstoff GmbH at IFAT stand 410 in hall B 3
