Abstract

The purpose of this study is to investigate the removal of dimethyl disulfide (DMDS) in the olefin rich Fluid Catalytic Cracking (FCC) C4 hydrocarbon mixture with the ion-exchanged β-zeolite. Effects of Si/Al ratio, metal cations, and the ion exchange level on the removal efficiency have been accessed by performing the breakthrough experiment with a model C4 mixture of 20 ppm DMDS in 40% n-Butane/60%1-Butene. The metal ions used for the preparation of ion exchanged zeolite are Ag(I), Cu(II), Ni(II), Fe(III), and Cu(I). The adsorption characteristics of 1-Butene and DMDS on the adsorbent have been studied through the temperature programmed desorption (TPD).
