Grace launched eight new FCC catalysts and additives in March 2011 in response to the unprecedented hyperinflation in the price of rare earth (RE). The REpLaCeR™ family of catalysts includes ResidUltra™, REBEL™, REACTOR™, REMEDY™and REDUCER™ for both hydrotreated and resid feed processing applications. Utilizing proprietary zeolites, Z-21 and Z-22, and formulated into Grace's alumina-sol catalysts, REpLaCeR™ catalysts offer similar activity, equivalent stability, and the same selectivity as conventional RE-based catalyst systems.
