Catalyst Recyclability & Green Metrics — 2D Top-Down View

A fresh catalyst bed converts substrate at full activity, but every real catalyst ages: metal can leach into solution, small particles can sinter into larger low-area clumps, or the surface can be slowly poisoned by trace impurities. This top-down 2D simulator runs a heterogeneous catalyst through successive reaction batches, applies a real deactivation mechanism of your choice after every cycle, and tracks live conversion, turnover and the cumulative E-factor — the standard green-chemistry waste metric — so you can see directly why keeping a catalyst active for more cycles (rather than discarding and replacing it) is one of the biggest levers for reducing process waste.
