MD FCC Catalysts - boosting middle distillates production in FCC

Maximizing middle distillates in FCC units. A range of catalysts is available from Ketjen for increasing the production of middle distillates in the FCC process while retaining the many other attractive features of this versatile bottom-of-the-barrel upgrading process. The key to success is to adjust the catalyst properties for maximum production of LCO while maintaining maximum bottoms (slurry oil) destruction and good product quality.

The middle distillate catalyst family caters to a wide range of feedstocks and operating conditions to enable a refiner to take full advantage of the profit potential in FCC. The catalysts designated AMBER™ MD is formulated for use with gas oils. CORAL™ MD and UPGRADER™ MD have been designed for upgrading residue feedstocks. All three provide excellent selectivity to LCO, exceptionally high bottoms conversion and superior metals resistance, stability and coke selectivity. CORAL MD is the catalyst of choice for residue units limited by FCC unit regenerator temperature, whereas AMBER MD and UPGRADER MD are suited to the most demanding operations without this constraint.

Figure 1 illustrates what is achievable as a function of conversion. Maximum advantage is taken by operating in Zone 2, where, with increasing conversion, the cracking of bottoms to LCO exceeds the cracking of LCO to lighter products, or in Zone 3, where small losses in LCO yield are compensated for by increasing gasoline and lower bottoms production.

  • UPGRADER™ and UPGRADER R+

    Unprecedented upgrading of residue in FCC. FCC units using conventional FCC catalysts are severely limited when diffusion constraints control conversion and bottoms upgrading, for example, in heavy-feed and/or short-contact-time operations. Even with high catalyst addition rates, bottoms conversion, ...

  • SMOOTHFLOW™ FCC additive

    The solution for FCC fluidization and circulation problems. SMOOTHFLOW from Ketjen offers a solution to FCC unit fluidization and circulation problems. Fluidization problems sometimes begin suddenly, often as the result of an unexpected process upset causing significant catalyst losses and possible mechanical ...

  • SOxMASTER-2™

    Optimal SOx reduction without rare earth for partial- and full-burn units. SOx reduction additives are designed to capture and remove the oxidized sulfur compounds present in the FCC unit regenerator and release them in the FCC riser. On release, the sulfur exits the FCC unit as hydrogen sulfide, along ...

  • DuraSOx™

    DURASOx™ SOx reduction additive is the culmination of intensive development work focusing on obtaining the most attrition-resistant SOx additive on the market without any performance compromises. It follows in the footsteps of Ketjen’s longest-marketed SOx additive, KDSOxTM, in that both take advantage ...

  • 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 ...

  • ELIMINOx™ - flexible combustion promotion with lower NOx emissions

    ELIMINOx™ is Ketjen’s most widely used non-platinum-containing combustion promoter. More than 20 refineries around the world have used it to provide excellent carbon monoxide (CO) oxidation and to control afterburn with significantly lower NOx emissions when compared with traditional platinum promoters. ...

  • AMBER™

    AMBER™ catalysts are frequently used, high-quality catalysts from the Ketjen portfolio and are manufactured using ADM-20 matrix technology, which is common to its high-accessibility catalysts. AMBER™ is the benchmark for maximum transportation fuels against which all other gas oil catalysts are measured. In ...

  • BCMT™-500 and BCMT-500-LRT

    Too often, profitability is lost because refiners lack adequate accessibility and bottoms cracking power in their catalyst. Ketjen has developed BCMT-500 additive, which features high accessibility and provides powerful functional bottoms conversion sites. BCMT-500 delivers many pre-cracking sites and ...
