摘要

柴油机尾气处理系统中脱除氮氧化合物（NOx）的催化剂易受硫的侵蚀而中毒。为避免SOx对净化NOx催化剂的毒害作用，一种有效的解决办法是将脱硫捕集器置于脱除NOx催化剂的系统之前来捕获柴油机尾气中的氧化硫（SOx）。本文针对贵金属催化剂、金属碳酸盐、金属氧化物等几种主要应用于柴油机脱硫捕集器的干式脱硫材料，主要阐述了各自的脱硫原理及性能，并分析了各种脱硫材料的研究现状和工业化应用前景，并指出了高性能且价格低廉的金属氧化物是未来应用于柴油机脱硫捕集器的主要方向。

Abstract

NOx removal catalysts in the diesel engine exhaust system are sulfur-sensitive. The DeSOx filter upstream of NOx removal system can capture SOx to prevent NOx removal catalysts from SOx poisoning in diesel engine exhaust. This paper is oriented toward some main dry desulfurization materials for DeSOx filter in diesel exhaust system, such as precious metal catalyst, metal carbonate and metal oxide. We laid emphasis on the desulfurization mechanism and performance of each material. The research status and industrial application prospect of those materials were also analyzed. It is pointed out that the cheap metal oxides with good desulfurization performance are appropriate for applications in the diesel DeSOx filters.

Key words： diesel exhaust system; DeSOx filter; dry desulfurization materials; desulfurization mechanism
