Several types of catalysts are used in reactions involving propylene, including:
1. Zeolite Catalysts: Used in the Fluid Catalytic Cracking (FCC) process to convert heavier hydrocarbons into lighter ones, including propylene. 2. Metallocene Catalysts: Employed in the polymerization of propylene to produce polypropylene with specific properties. 3. Heterogeneous Catalysts: Such as Ziegler-Natta catalysts, which are widely used in the polymerization process. 4. Homogeneous Catalysts: These include various transition metal complexes that facilitate the production of fine chemicals from propylene.
