摘要
脱硫剂再生过程是高温煤气脱硫工业化应用必备的关键环节之一。本文重点综述了含氧气氛、水气氛、水氧混合气氛和二氧化硫气氛中高温煤气脱硫剂的再生行为。以硫资源化回收作为高温煤气脱硫剂再生的目标,分析了不同再生气氛以及不同再生操作条件对高温煤气脱硫剂再生行为的影响。最后对今后高温煤气脱硫剂的再生研究提出了几点建议。
Sorbent regeneration is a key technology in the industrial applications of high temperature coal gas desulfurization.This review focuses on the regeneration behaviors of desulfurization sorbents in different atmospheres composed in regeneration gas,such as O2,H2O,H2O-O2 or SO2.Results revealed that the regeneration behaviors were distinctly affected by different regeneration gas atmospheres and technical conditions.In addition,the sulfur recovery research should be combined together with the sorbent regeneration.Finally,suggestions for further study on sorbents regeneration are proposed.
