  • DuraZOOM™ - industry-leading olefin and octane enhancement

    DuraZOOM additive is the latest in a long line of light olefins and octane enhancers manufactured by Ketjen. ZSM-5 additives were developed by Mobil Oil Corporation and first used in 1983 as octane enhancers necessitated by the phasing out of tetraethyl lead. Since then, their use has grown enormously worldwide. The initial applications required relatively low levels of ZSM-5 crystal. More recently, the use of ZSM-5 additives has shifted from octane enhancement to propylene generation. ...

  • Equipment design matters

    Many attractive projects fail to meet expectations at startup. Disappointing performance often results from bad simulation practices and/or poor equipment design rather than faulty execution. Refineries are currently considering FCC revamps to increase olefins for more alky unit feed, maximize LCO product recovery, and minimize slurry product by producing HCO for hydrocracker feed. These changes raise fractionator operating temperature. Higher temperatures require better process ...

  • FCC Main Fractionator Coking

    One common cause for coking is poor vapor distribution. Packing selection in the Slurry P/A section is critical to ensure good distribution and reliable performance. Mellagrid™ combines the performance of Mellapak™ with the robustness of traditional grid. Resists coking and fouling due to its smooth surface and geometrical. Better de-entrainment and separation efficiency than traditional grid. Efficient dissipation of temperature. Excellent mechanical strength.

  • FCC technical support, industry-leading service

    Grace technical service engineers regularly visit refineries to review unit operating data, evaluate catalyst management and unit performance, as well as provide specific recommendations to optimise unit operation. Grace can provide expert advice on operational problems concerned with the mechanical integrity of the FCCU. For example, issues such as cyclone performance, stripper efficiencies, circulation problems, transfer line problems, slurry circuit fouling, or high unit erosion ...

  • Fourte®

    Innovative Fluid Catalytic Cracking (FCC) Catalyst for butylenes maximization Fourte® maximizes butylenes production in the FCCU and increases gasoline octane while preserving catalyst activity. Technology Fourte is BASF’s butylene maximization FCC catalyst developed on the novel Multiple Framework Topologies (MFT) technology. The technology behind Fourte delivers high selectivity toward C4 olefins by optimizing performance across five key factors: rare earth, activity, ...

  • Fourtune™

    Next generation Fluid Catalytic Cracking Catalyst Performance for butylenes maximization over propylene. Fourtune™ delivers highest butylenes yields and $0.30/bbl profitability improvement. Results Fourtune™ outperformed the incumbent catalyst and generated significant profitability for the refinery via increased butylenes yields, improved butylenes selectivity and increased gasoline octane. A post audit of the Fourtune™ catalyst was performed using multiple tools, including ...

  • Improve contaminant metals flushing with TITAN™

    The escalating price of rare earth in fluid cracking catalyst sparked increased demand from refiners for equilibrium catalyst (Ecat) as a means to control expenses. During this same period, the available supply of high quality, low metals Ecat had decreased. In response to the shrinking supply of Ecat, Grace introduces TITAN™, a unique catalyst solution for removing contaminant metals from refining operations. Unlike traditional equilibrium catalysts, TITAN™ is completely ...

  • INTERCAT FCC additives and catalyst handling technologies

    Most refiners now find it essential to use catalytic additives to supplement the host FCC catalyst in order to achieve the desired unit performance, product quality, and environmental emissions targets that must be met. Johnson Matthey is the foremost supplier of FCC additives and addition systems, specializing in the development, manufacture, sale, and technical support of both additives and addition systems for the refining industry. Our INTERCATTM range of FCC additives and ...

  • IsoTherming® Hydroprocessing technology

    Growing global demand for transportation fuel continues to drive refiners toward operations that maximize hydroprocessing capacity and capability either through unit debottlenecks or new unit construction. More stringent environmental regulations and the processing of cost-advantaged sour and heavy feed stocks make meeting this demand even more challenging. IsoTherming® hydroprocessing technology is a commercially proven process that provides refiners a more economical ...

  • KOC-15™ Flexible and effective way to lower afterburn in your FCC unit

    KOC-15™ additive is Ketjen’s most widely used platinum-based combustion promoter, and is commercially proven to provide many refiners with a reliable, low-cost and flexible solution to afterburn and excess carbon monoxide (CO) emissions. In the regenerator, the coke (carbon) on the spent catalyst is burned to form carbon dioxide (CO2). During combustion of carbon to CO2, CO forms as an intermediate. The conversion of carbon to CO in the presence of oxygen occurs rapidly; ...

  • Low and zero rare-earth FCC catalysts

    Rare-earth metals are an important component of FCC catalysts, as well as being a key raw material for many strategic industries with applications ranging from military devices to electronic components. In addition, they are essential constituents in newly evolving green technologies, such as hybrid cars and wind turbines. Rather ironically, rare-earth metals are not so rare, however they tend to be concentrated in hard to extract ore deposits. As a result, the world’s ...
