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, catalyst activity and coke and gas selectivity suffer because of the inevitable mass transfer limitations. As a result, the total FCC product value and profitability are compromised.
Ketjen’s UPGRADER family of premium-residue FCC catalysts, which is designed specifically for heavy-feed and diffusion-limited operations, delivers significantly improved diffusion through unsurpassed accessibility, advanced matrix performance and more zeolite-based cracking, all which contribute to superior residue processing.
UPGRADER catalysts were developed through an innovative improvement to Ketjen’s TOPAZ™ manufacturing technology. One measure of UPGRADER’s unique performance is the proprietary Albemarle Accessibility Index (KAI), which directly measures the dynamic diffusion of high-molecular-weight molecules into an FCC catalyst particle and correlates with a catalyst’s ability to crack residue feedstocks. UPGRADER catalysts consistently record the highest AAI levels in the industry.
Ketjen’s latest residue catalyst, UPGRADER R+, takes advantage of the same technology as UPGRADER, but is further optimized for units requiring catalysts with even better coke selectivity characteristics through further adjustment of its metals resistance.
