Selective hydrogenation

Increase the value of your products

In the thermal cracking process, small amounts of unwanted, unsaturated dienes and/or acetylenes are co-produced and end up in the product streams, where they must be removed via selective hydrogenation.

Topsoe offers high-activity, high-selectivity catalysts that convert these unwanted compounds into higher-value products, ensuring a product stream composition that always meets specifications.

Catalysts for selective hydrogenation

SH-501 catalyst

A high-nickel catalyst based on an alumina carrier. It utilizes an optimized carrier system to selectively hydrogenate styrene and diolefins in pygas and naphtha stream.

Applications within this area

Benzene hydrogenation

Convert benzene to high-purity cyclohexane in an affordable process that ensures compliance with benzene limits in the gasoline pool with our market-leading catalysts.

Petrochemical sulfur guards

Our sulfur guards protect your downstream catalysts by removing hydrogen sulfide and other sulfurous compounds and ensure pipeline specifications, while helping you reduce operating costs.
