AFX™ catalysts for increased propylene production from FCC units

New technology to meet propylene demand Fluid Catalytic Cracking (FCC) units are playing an increasingly important role in meeting the growing worldwide demand for propylene. To help refiners meet this demand better, Ketjen has introduced the innovative AFX catalyst technology and catalyst family, which are designed specifically for operation at high-propylene yield.

Before AFX, propylene production from an FCC unit with a traditional catalyst was limited. ZSM-5 based additives can help boost the conversion to propylene; however, the base catalyst determines what level of propylene is ultimately achieved. AFX catalysts are technologically advanced and designed to maximize the propylene potential from FCC units, both when used alone and when supplemented with an olefins-octane additive.

The unique design of AFX, with its optimized balance between micro-, meso- and macro-activity, proprietary specialty zeolites and high accessibility, minimizes secondary cracking reactions, such as hydrogen transfer, and maximizes propylene production. AFX can be applied in both conventional and the latest FCC unit designs to increase propylene production to at least 12 wt%. AFX can be formulated for the entire range of feedstocks, from heavy residues to hydrotreated gas oils.

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 ...
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 ...
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 ...
