Fuel-upgrading catalyst boosts lifetimes and supports sustainability

By Scott Jenkins |

A new fuel-upgrading catalyst for petroleum refineries has several features that boost sustainability and minimize environmental impact. In March, specialty chemical maker Clariant (Muttenz, Switzerland; www.clariant.com) launched PolyMax 850, a new generation of its PolyMax catalyst series. The new catalyst, intended to convert olefins created during cracking processes into high-octane gasoline and organic solvents, was designed to allow significantly lower operating temperatures in the refinery unit, Clariant says, which reduces CO2 production. Also, PolyMax 850 offers a longer service life than other catalysts in the series. The catalyst’s manufacturing process is also designed for sustainability, Clariant says. It is manufactured from diatomaceous earth and phosphoric acid in a newly developed process that generates zero wastewater. At the end of its life, the PolyMax 850 catalyst can be completely recycled into fertilizers and other useful phosphorous-containing products, Clariant says.
