0　前言在以轻油、炼厂气、煤为原料制氨、制氢及合成甲醇等化工产品时 ,大多使用高效昂贵的金属催化剂 ,即使微量硫也会使催化剂失活 ,因此要对原料进行精脱硫。目前国内各大、中型合成氨、合成甲醇等装置均使用氧化锌脱硫剂进行精脱硫 ,它可保证生产装置长周期运转 ,但催化剂 0 Introduction In the light oil, refinery gas, coal as raw material ammonia, hydrogen and synthetic methanol and other chemical products, mostly using expensive metal catalyst, even if a trace of sulfur will make the catalyst deactivation, the raw material to be carried out Fine desulfurization. At present, domestic large, medium-sized synthetic ammonia, synthetic methanol and other devices use zinc oxide desulfurizer for desulfurization, which can ensure long-period operation of the production plant, but the catalyst
