Solving the challenge of chemical plastic recycling

Chemical plastic recycling is essential if we are to reduce the growing environmental burden of plastic waste. Instead of being incinerated or ending up in landfills, mixed plastic waste can be converted to pyrolysis oils, which can be used as feedstock for the sustainable production of valuable chemicals.

In this emerging and complex field, producers are faced with continuously changing contaminants in a feed that contains diverse types of plastics. Clariant’s new HDMax® catalysts and ClaritTM adsorbents answer the need for flexible and economical solutions to remove a wide range of impurities, regardless of process configuration or plastic waste feedstock, allowing them to achieve cracker-compatible pyrolysis oil.

Our contribution to a more circular plastics economy

HDMax catalysts and Clarit adsorbents for pyrolysis oil purification

Clariant is solving the challenges of pyrolysis oil purification with its new HDMax catalysts and Clarit adsorbents. The powerful, dual solution is specially developed for removing a wide range of impurities from pyrolysis oil, regardless of process configuration or plastic waste feedstock. Used together, the adsorbents extend the lifetime of the catalysts.

This allows flexible, cost-efficient production of pyrolysis oil that is compatible with steam crackers. Our comprehensive solution includes operational support throughout the lifetime of our products to ensure optimum performance and results.

What are your benefits?

Our advanced solution for chemical plastic recycling consists of Clarit adsorbents for the pre-treatment step of pyrolysis oil purification, followed by HDMax series catalysts for subsequent hydrogenation. The complementary products ensure highly effective removal of a broad range of contaminants, such as metals, chlorine, nitrogen, oxygenates, silicon and phosphorous.

The combination gives producers greater flexibility regardless of feedstock changes or process configuration. Our broad portfolio also allows us to offer customized solutions to suit a variety of requirements. Overall, producers are able to process larger volumes of pyrolysis oil of higher quality at lower costs.
