Abstract

Species formed from acetylene (Ay) adsorbed in zeolite Y, mordenite, beta, and ZSM-5 were studied, and the dynamics of Ay physisorption was characterized. The rate of micropore diffusion governed the transport in Na-mordenite, while sorption was the rate limiting process step for all the H-zeolites. The equilibrium constants of Ay sorption were determined using the Langmuir rate equation to describe the pressure dependence of the sorption time constants. The n-octane hydroconversion activity of Pt/H-zeolites increased linearly with the Ka of Ay sorption on the H-zeolites. This is an abstract of a paper presented at the 13th International Zeolite Conference (Montpellier, France 7/8-13/2001).
