摘　　要：探究重整氢低温脱氯剂床层泥化板结的原因,研究了活性组分吸水性强弱对其结构和机械强度的影响。成功开发出氧化铝基脱氯剂和双金属氧化物脱氯剂,采用XRD、XRF、氮吸附法对脱氯剂进行了表征,并在实验室小试装置上进行了性能测试。结果表明,该脱氯剂无论是结构还是性能指标都能与国外同类脱氯剂相媲美,新开发的两款脱氯剂用于重整氢低温脱氯具有良好的脱氯精度,能有效解决脱氯剂使用过程中因床层泥化板结而造成寿命短、阻力降增大、卸剂困难的问题,也能很好的解决后系统铵盐结晶堵塞的问题。The causes for the bed sludge formation of the low-temperature chloride removal adsorbent for reforming hydrogen were explored,and the influence of the hydroscopicity of the active component on its structure and mechanical strength were studied.Alumina-based chloride removal adsorbents and bimetallic oxide chloride removal adsorbents were successfully developed,and characterized using XRD,XRF and nitrogen adsorption methods.Catalyst performance was tested in a small-scale experimental apparatus.The experimental data show that the chloride removal adsorbents is comparable to similar foreign chloride removal adsorbents in terms of both structure and performance indexes.The two newly developed dechlorinating agents for low-temperature dechlorination of reforming hydrogen have good dechlorination accuracy,which can effectively solve the problems of short service life,increased resistance drop,and difficult unloading caused by bed mud and agglomeration during the use of dechlorinating agents.They can also effectively solve the problem of ammonium salt crystallization blockage in the rear system.
