Features

 

Rare earth modification: Rare earth ions increase acid sites and strength, enhancing catalytic activity in cracking.

 

FAU-type microporous structure: Three-dimensional pores (~0.74 nm) allow efficient diffusion of hydrocarbons and reactants.

 

High surface area and crystallinity: Provides abundant active sites and ensures effective contact with reactants.

 

Enhanced stability: Thermal and hydrothermal resistant, suitable for high-temperature processes like FCC.

 

 

Key Applications

 

Fluid Catalytic Cracking (FCC)
The primary active component in FCC catalysts for converting heavy oil fractions into lighter products such as gasoline and diesel. REY improves conversion rates and product selectivity compared to standard Y zeolite.

 

Hydrocracking and Heavy Oil Processing
Supports cracking and hydrogenation reactions in combination with metal function catalysts (e.g., NiMo), enhancing hydrocracking performance.

 

Chemical Catalysis
Applied in acid-catalyzed reactions such as isomerization, alkylation and deolefinization in both petrochemical and fine chemical synthesis.

 

Adsorption and Separation
Its porous structure also makes REY suitable for adsorption of VOCs and other gases in purification and environmental applications.
