摘要: This brief review has the objective of showing the role of the rare earth in the context of Fluid Catalytic Cracking (FCC). REHY and RENaY zeolites, two of the most important components of FCC catalysts, were extensively studied in the past years. Their properties were evaluated in different conditions and the discussions of their main characteristics were revisited. It has been shown that RE elements migrate to smaller cages upon calcination and, once located in these cages, they form bridges with framework oxygen atoms, stabilising the zeolite …
