在固定床高压微反装置上,考察了预硫化型NiMoS/γ-Al2O3催化剂上二苯并噻吩(DBT)加氢脱硫(HDS)反应和喹啉加氢脱氮(HDN)反应之间的相互影响. 结果表明,喹啉对DBT的HDS反应具有强烈的抑制作用,其中对加氢路径比氢解路径的抑制作用更强,这是由喹啉及其HDN反应的中间产物与DBT在活性位上的竞争吸附造成的. 在300和340 ℃时,喹啉对DBT的 HDS反应中氢解路径的抑制程度与其HDN中间产物的相对含量紧密相关. 而DBT能够提高喹啉的脱氮能力,这源于其HDS产物H2S. H2S促进了催化剂表面硫阴离子空穴向B酸位的转化,从而提高了喹啉HDN中间产物分子的 C(sp3) - N 键的断裂能力. HDN活性相的保持不需要过多的硫原子.
