FCC pretreatment catalysts

High-performance catalyst systems tailored to meet refiners’ operating objectives. Refiners worldwide are reporting significantly enhanced refinery economics after working with Criterion Catalysts & Technologies to optimise the performance of their fluidised catalytic cracking (FCC) pretreatment units. Criterion offers a range of industry-leading FCC pretreatment catalysts (Figure 1), and works closely with refiners to design catalyst systems that match their specific performance goals.

CATALYST SYSTEM DESIGN
We recognise that installing industry-leading catalysts will not, on its own, deliver maximum value; the design of the overall catalyst system is also critical. It is essential that this takes into account  site-specific constraints such as hydrogen availability, FCC unit capabilities and feedstock options, as well as the refiner’s operational objectives in terms of, for instance, cycle life, product slate and emission targets.

For this, we follow a highly diagnostic process in which we listen to customers to gain a thorough understanding of their situation. This enables us to devise a value-adding catalyst system designed to lie within those constraints and leverage the most value from their assets.

For feedstocks with a high content of metals contaminants, we typically recommend a top layer of high-performance demetallisation catalyst from our SENTRY portfolio. This reduces metals slip to the more active catalyst loaded in the rest of the reactor, which is less tolerant to metal, and reduces the metals in the FCC feed. The rest of the reactor can then be loaded with a high activity catalyst system featuring products from our portfolio of FCC pretreat catalysts seen in Figure 1.
