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 supply comes from only a few sources; China alone accounts for 95% of the world’s rare-earth metal output. Recent export quota restrictions on rare-earth metals from China have caused the price of rare-earth metals to rapidly rise.
Grace Davison has a long history of providing innovation in the development of FCC catalysts, including the addition of rare-earth metals to stabilize the zeolite Y component of the FCC catalyst, which was revolutionaryfor catalytic cracking. As the only FCC supplier with flexible manufacturing platforms, Grace also has a successful history of developing rare-earth free FCC catalysts. We introduced new zeolite components that enhanced gasoline octane in the 1990’s, delivering activity and stability without the use of rare earth. Later in the 1990’s Grace developed Z-21, a rare-earth free stabilized zeolite Y. Based on this new technology the NEXUS® catalyst family was commercialised in 1997, as a rare-earth free catalyst family for low-metal feed applications. The NEXUS® catalyst has since been used in 10 applications.
