硫化

The surface reaction of thiophene leads to the sulfidation of molybdenum nitride catalysts and the formation surface σ-bonded C〓 species, which are considered as the reasons for the deactivation of nitride catalysts in HDS process.

噻吩的表面反应使得催化剂表面被硫化，并产生σ键合的表面C〓物种，这些被认为是氮化物催化剂在噻吩HDS反应中失活的原因。H〓S对氮化钼表面位的影响较噻吩更明显。
