Phosphoric acid catalysts are used to convert olefins – produced during cracking processes in oil refineries – to gasoline, solvents or starting materials for plasticizers. Moreover, the catalyst allows operation at significantly lower temperatures, thus saving considerable energy. Besides improving quality and cost efficiency, Polymax 850 also supports sustainable fuel production. Not only does it reduce demand on raw materials, but also significantly decreases greenhouse gas emissions. Preliminary calculations estimate an annual CO2 reduction of around 100,000 tons compared to other state-of-the-art catalysts.

From start to finish, PolyMax 850 is designed to minimize environmental impact. The catalyst is produced from diatomaceous earth and phosphoric acid in a process that does not generate wastewater. After a long service life at the refinery, Polymax 850 can be completely recycled into fertilizers or other useful phosphorous compounds. Reutilization already occurs with almost 65% of all spent Polymax catalysts, helping to reduce the consumption of phosphate rock in the production of phosphorus. Clariant actively works with international partners to further increase recycling rates with the aim of achieving complete lifecycle management for Polymax series catalysts.
