PDS催化脱硫反应机理的研究(Ⅱ)——反应机理模型的实验佐证

STUDY ON THE CATALYZED DESULPHURIZATION MECHANISMS OF PDS Ⅱ THE EXPERIMENTIAL CONFIRMANION OF THE REACTION MECHANISM MODEL

本文通过吸收光谱、顺磁共振光谱、红外光谱及电化学分析方法等实验手段测定了 PDS 催化脱硫反应过程中配位中心钴离子价态的变化、O_2^-和 HO_2的生成以及再生结构中多硫链的形成。

In this paper,we have carried out the experimential dete- rmination on the valence variatiation of cobalt cation,the fo- rmation of O_2^- anion and HO_2 free radical,and the growth of multisulphur chain in the regeneration structure in the cataly- zed desulphurization process of PDS by the absorption,param- agnetic and infrared spectroscopy as well as the analysis met- hod of electrochemistry.This work has provided an experime- ntfal confirmation for the model of two-center theory.
