http://demonstrations.wolfram.com/AdsorptionIsothermsOfEthyleneInNaXZeoliteStructureFAU/ The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. This Demonstration plots adsorbtion versus pressure, P, at various temperatures for ethylene (C2H4 ) in NaX, known as faujasite zeolite structure (FAU). The amount adsorbed, n (expressed in mol/kg), increases at low temperatures and high pressures. The ... Contributed by: Housam Binous
