Adsorption Catalyst Surface Area Measurement - 1 The active area of supported transition metals can be determined by adsorb- ing carbon monoxide. Carbon monoxide is known to adsorb associatively on ruthenium at 100C. Use the following uptake data for the adsorption of CO on 10 wt% Ru supported on Al2O3 at 100C to determine the equilibrium adsorption constant and the number of adsorption sites. Pco (torr) 100 150 200 250 300 400 CO adsorbed (umol/g cat) 1.28 1.63 1.77 1.94 2.06 2.21 2.4 model data 2.2 CCO = = 2 EmKicco 1 + Kicco 1.8 (6/1ourt) 02 1.6 1.4 0 1.2 1 1 8 1 14 1 16 4 6 10 11 12 co (umol/cm3)
