Clariant launches new catalyst

Phosphoric acid catalysts are used to convert olefins – produced during cracking processes in oil refineries – to gasoline, solvents or starting materials for plasticisers. 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 t compared to other catalysts.

From start to finish, PolyMax 850 is designed to minimise 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. Reutilisation 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.

Stefan Heuser, Senior Vice President & General Manager Business Unit Catalysts at Clariant, stated, "Due to fluctuations in crude oil prices, the fuel industry is seeking more effective and efficient ways to produce high quality fuels. PolyMax 850 presents a powerful solution. It increases yields and quality, while reducing emissions and waste."
