Hydrogen uptake in palladium and ruthenium exchanged zeolite X

摘要: Abstract The hydrogen adsorption properties and uptake capacities of NaX its palladium ruthenium exchanged forms were investigated at 77 K in a static volumetric setup up to 1 bar, 303 K 333 K gravimetric system 5 bar. All the isotherms Type I with maximum capacity shown temperature. Hydrogen found be decreasing as exchange levels increases. Chemisorption was observed due chemical interaction between transition metal cations molecules. 5 bar for zeolite X value around 85 cm 3 /g. Grand canonical Monte Carlo simulations also performed study H 2 these zeolites well 333 K. simulation studies are suitable establishing correlation microscopic behavior adsorbate macroscopic which measured experimentally, such isotherms.
