Preparation of bifunctional NiPb/ZnO-diatomite-ZSM-5 catalyst and its reactive adsorption desulfurization coupling aromatization performance in FCC gasoline upgrading process

► Pb-modified Ni/ZnO adsorbent can efficiently suppress olefin saturation. ► Pb-modified Ni/ZnO-DZSM-5 catalyst exhibits high aromatization performance of olefin. ► Coupling process can achieve ultra deep desulfurization without loss of octane number.
