摘要
采用程序升温脱附 (TPD)、原位红外 (IR)技术分别对乙硫醇、噻吩这两种不同的硫化物在FX 0 2催化剂上的吸附性能进行了较深入的研究。结果表明 ,温度是影响硫化物在FX 0 2催化剂上吸附的重要因素。对乙硫醇而言 ,其在FX 0 2催化剂上的吸附量随温度的变化 ,符合经典吸附理论 ,即吸附量随温度升高而下降 ;而对噻吩而言 ,当吸附温度较低时 ,同样符合经典吸附理论 ,但当吸附温度升高至 35 0℃时 。
By means of TPD and in situ IR spectroscopy for studying the adsorption of different sulfides on FX 02 catalyst, it is found that temperature plays an important role for sulfides to be adsorbed on FX 02 catalyst. As for ethanethiol, the rule of adsorption is in conformty to the classical adsorption theory, so does thiophene even at comparatively low temperatures, but with the adsorption temperature's rising up to 350 ℃, the influence of diffusion in β zeolite and the pore structure of catalyst can not be neglected. The classical adsorption theory is broken because of hole.
