摘要
PDS(酞菁钴磺酸铵)法催化脱硫技术因适用于高硫化氢工业气体的净化而受到国内外的重视。在PDS脱 硫机理的研究中,对双核金属酞菁类化合物催化H2S液相反应的催化电子转移机制进行了探讨。在工业生 产脱硫装置上,通过改变工艺控制指标、试验PDS脱硫催化剂与ADA脱硫催化剂混合脱硫、试验PDS脱 硫催化剂为主要脱硫催化剂、试验PDS脱硫催化剂溶液中添加少量ADA脱硫催化剂达到脱硫目标并取 得多种效果等。开展PDS脱硫催化剂取代ADA法脱硫等工业实践,逐步实现了PDS法脱硫,达到了经济 技术指标的优化。
catalytic mechanism of electron transfer for the oxidation of H2S in liquid phase catalyzed by binuclear matallo phthalocyanine compounds has been raised in the article.The process of election transfer is the rate controlling step for the whole reaction. Test was made to use the reformed ADA process for desulfurization with PDS catalyst in a commercial unit.The results have shown that the PDS mixture process is appropriate for purification of high-sulfur coal gas, and its desulfurization efficiency reached 98%-99.3%.
