How does catalyst selection impact propylene yield in a Fluid Catalytic Cracking (FCC) unit?

Catalyst selection significantly impacts propylene yield in a Fluid Catalytic Cracking (FCC) unit by influencing the cracking reactions and product selectivity. FCC units use catalysts to break down large hydrocarbon molecules into smaller, more valuable products, including gasoline, diesel, and olefins like propylene. The catalyst's properties, such as its acidity, pore size distribution, and metal con....
