en.Wedoany.com Reported - Evonik has introduced a portfolio of adsorbents and catalysts designed to improve the quality of pyrolysis oil, enabling its use as a supplementary feedstock to fossil naphtha in steam crackers. Among these, the Purocel™ product line is specifically engineered to remove impurities such as chlorine, nitrogen, and silicon from pyrolysis oil, which can otherwise harm cracker operations.

In terms of technical approach, Purocel™ 505 uses catalytic reactions to separate chlorine atoms from large molecules and subsequently adsorbs and binds hydrogen chloride, achieving up to three times the chloride removal capacity of conventional methods. For feedstocks with stricter specifications, Evonik combines adsorption with hydrotreating, using hydrogen to convert residual impurities into volatile compounds and recovering the Purocel H catalyst for resource efficiency.

Regarding equipment and integration, Evonik offers pre-configured modular tower units under its Rocket Technology concept, loaded with adsorbents such as Purocel™ 510. These units can be flexibly connected to pyrolysis plants and steam crackers, enabling purification with lower investment and reduced downtime.

Chemical recycling primarily targets plastic waste streams that are heavily contaminated or unsuitable for mechanical recycling. Evonik positions its technology as a cross-scale system solution, aiming to expand the use of pyrolysis oil in the petrochemical value chain, thereby reducing dependence on fossil feedstocks, minimizing environmental impact, and enhancing supply resilience.
