Zeolite Catalytic Cracking: Fluidized Bed Dynamics

Interactive 3D fluidized-bed reactor: raise the gas velocity past the Wen-Yu minimum fluidization velocity to bubble a zeolite catalyst bed, crack hydrocarbon feed, and watch coke buildup deactivate the catalyst until you regenerate it.

Fluid Catalytic Cracking (FCC) units suspend a zeolite catalyst in an upward stream of hot hydrocarbon vapor, converting heavy crude fractions into gasoline-range products. This simulator renders a real fluidized bed in 3D: drag the gas superficial velocity across the Wen–Yu minimum fluidization velocity U_mf to flip the catalyst bed from a static packed column to a churning, bubbling suspension, watch the bed expand and particles circulate, and track how hydrocarbon feed cracks into lighter product on the catalyst's acid sites — while coke deposition (the Voorhies correlation) steadily deactivates that same catalyst until you regenerate it.
