(Arabian Oil and Gas) -- Grace Davison, an operating segment of W. R. Grace & Co. , has announced the successful global commercialisation of eight fluid catalytic cracking (FCC) catalysts and additives with zero or low rare earth content.
Launched in the first quarter of 2011, the REpLaCeR family includes five new catalysts for both hydrotreated and resid feed processing with zero and low rare earth content: resolution, REBEL, REACTOR, REMEDY and REduceR FCC catalysts. The REpLaCeR family of catalysts utilises proprietary zeolites and state-of-the-art stabilization methods to deliver performance similar to current rare earth-based FCC technologies.
In addition, Grace has recently introduced ResidUltra, a new catalyst with 40% less rare earth than benchmark resid catalysts. Finally, a series of low rare earth environmental additives is currently in commercial trials. These include Super DeSOX-OCI and Super DeSOX-MCD sulfur transfer additives.
