Shape-Selective Zeolite Catalysis: The Molecular Sieve (2D)

This 2D companion strips the same molecular-sieve mechanism down to a top-view diffusion diagram: a mixed feed of three real hydrocarbons — n-hexane, isooctane and mesitylene, each carrying its literature kinetic diameter — random-walks toward a zeolite membrane pierced by evenly spaced pore gates whose diameter you control. Every arrival is a real geometric pass/block test (molecule diameter versus pore diameter); only the molecules that fit reach the internal active site, react at a rate you set, and exit as product, while the live panel tracks per-species feed, admission, and product counts alongside the running selectivity and yield.
