Abstract

Ni(Co)HZSM5, Ni(Co)HMOR and NiNaY zeolites were characterized by thiophene adsorption and hydrodesulfurization (HDS) reaction. The adsorption process was studied by microgravimetry and infrared (IR) spectroscopy. Thiophene interacts with H⁺ or Na⁺ but not with (NiOH)⁺ in the unsulfided samples. Ring opening and oligomerization reactions of thiophene are observed over the acidic ZSM5 and MOR zeolites. These reactions produce coke during the temperature programmed desorption (TPD) of thiophene. The HDS with C-S bond cleavage is facilitated by hydrogenation of thiophene over SH groups in the sulfided NiNaY zeolites.
