摘要：
A bifunctional Ni2P/SAPO-11 catalyst for the upgrading of fluidized catalytic cracking (FCC) gasoline was constructed to achieve the simultaneous removal of sulfur and prevention of octane number loss. In the preparation of Ni2P/SAPO-11, a modification with an ammonia post-treatment led to improved dispersion and high catalytic performance. Adsorption and kinetic study demonstrated that thiophene preferentially and more strongly occupied the Ni2P sites, so as to inhibit the undesired saturation of 1-hexene and facilitate the parallel skeletal isomerization on Ni2P/SAPO-11. The concerted synergy of Ni2P crystallites for hydrodesulfurization and moderate Br & oslash;nsted acid sites of SAPO-11 for isomerization led to full conversion of thiophene and 1-hexene with 74 % selectivity to branched isomers at 320 degrees C and 1.5 MPa.
