AbstractPropene adsorption isotherms, breakthrough curves and temperature programme desorption profiles have been obtained for six different crystalline materials with distinctive framework structures (3D and 1D) and a variety of Si/Al ratios and cations (four zeolites: Silicalite-1, BETA, ZSM-5, Mordenite; and two silicoaluminophosphate molecular sieves: SAPO-41 and SAPO-5). Moreover, for a proper evaluation of the solids in a propene trap under cold start conditions, cold start tests have been performed, carrying out four cycles (adsorption/desorption) to analyze the ageing process of the materials. A detailed analysis of the experimental results points out that materials with high equilibrium propene adsorption capacity at 30 °C, where propene is mainly chemisorbed and, which presents some kinetics restrictions, seem to be the best for a propene trap under cold start conditions. BETA and ZSM-5 zeolites and SAPO-5 silicoaluminophosphate molecular sieve are promising materials as propene traps.
