Processing with Totsucat HC ensures thathandling of sulfiding chemicals. hydrocracking catalysts function as designed without the need to spend valuableNegligible amounts of H2S are released production time on in-situ sulfiding. In addition, these catalysts are oftenduring reactor heat up, protecting sulfur passivated with ammonia after the sulfiding step. If required, Totsucat HC can alsosensitive units downstream and avoiding include ex-situ nitrogen passivation, enabling the refiner to avoid ammoniasulfur releases to the stack during tail gas injection.

Totsucat E works especiallyshut down.

Withcatalyst prior to activation is eliminated. Totsucat E, the catalyst will reach full activity within hours of startup instead ofThe catalyst load will achieve peak days. Totsucat E pre-activated catalysts can also be delivered in a passivatedperformance since sulfiding and activation form that makes it possible to load the reactor under air.has been controlled at very preciseconditions by the patented Totsucat START UP WITH CRACKED FEEDS - Eurecat has developed anprocess. exclusive procedure to gently moderate catalyst activity following sulfiding. This unique process, called Totsucat CFP, allows the direct introduction of cracked or heavy feeds without the 3-4 day delay typically recommended by catalyst manufacturers. Catalysts treated with Totsucat CFP are no longer ultra active after sulfiding, allowing the refiner to gradually introduce cracked and heavy feedstocks during the first hours of a startup without causing permanent damage to theSulfiding Technologies catalyst. Excess coke and gum formation will be prevented since the catalyst activity has been carefully modified following activation.
