IFAT 2012: HOK activated lignite in action around the world as efficient filter technology in environmental protection

Rheinbraun Brennstoff GmbH at Munich trade fair showcasing innovative product solutions for sewage and waste-gas cleaning

Cologne. – From 7 to 11 May 2012, Rheinbraun Brennstoff GmbH (RBB) will be at this year’s IFAT ENTSORGA in Munich to present innovative product solutions for sewage and waste-gas cleaning based on HOK activated carbon produced from Rhenish lignite.

Activated lignite, produced by RWE Power AG in the so-called hearth furnace process for use in numerous applications in environmental protection and marketed worldwide by RBB under the trademark “Activated Lignite HOK”, boasts special properties as an adsorption and filter material.

Typical fields of application – in addition to sewage treatment and drinking-water purification – are waste-air and waste-gas treatment in refuse incineration and in the steel industry where HOK is employed around the world as a low-cost and highly effective adsorbent.

It is the favourable pore structure and the catalytic properties of HOK activated lignite in particular that enable it to retain a whole host of pollutants. These include dioxins and furans, but also numerous other organic components as well as a range of heavy metals – including mercury.

HOK activated lignite: low-cost adsorbent at unvarying high quality level

Pyrolysis and activation of the lignite mined from RWE Power AG’s opencast pits in the vicinity of Cologne are based on a process optimized down the decades, the hearth furnace process, which also gave the product its German name – Herdofenkoks HOK – and ensures a low-cost mass product at an unvarying high quality level. At present, RWE’s Rhenish upgrading plants produce an annual quantity of some 180,000 tons in accordance with DIN ISO 9001.

At the world’s premier trade fair for innovations and services in water, sewage, waste and raw-materials management, which is fully booked, the roughly 2,700 exhibitors expect to attract over 100,000 trade-fair visitors from 180 countries.

Interested trade visitors are cordially invited to meet representatives of Rheinbraun Brennstoff GmbH at fair stand 514, hall A3, to find out about the latest product solutions and application examples in filter and environmental technologies based on activated lignite.

Aktivkoks wird auf Basis rheinischer Braunkohle im sogenannten Herdofenverfahren hergestellt. Die besonderen Eigenschaften der rheinischen Braunkohle in Verbindung mit den Aktivierungsbedingungen im Herdofen führen zu einem Aktivkoks, der seit vielen Jahren als preiswertes Adsorptionsmittel und Filtermittel in den unterschiedlichsten Anwendungen der Abgas- und Abwasserreinigung zum Einsatz kommt.
