高选择性脱硫吸收剂的研制
Development of Desulphurizer with High Selectivity
-
摘要: 利用位阻胺原理,合成并评选出了一高选择性的脱硫剂,考察了不同使用方法的效果和其工业上的适用性。研究表明,开发的脱硫剂在H2S、CO2等酸性气共存情形下,对H2S具有高选择性、高负荷及工业上不同酸性气组成下的良好适应性。该脱硫剂合成条件温和,原料易得,它可以单独低浓度水溶液状态使用,也可取微量与工业上现行脱硫剂复配应用。Abstract: Based on the principle of hinded amine, a desulfurizer which can be synthesized easily with high H2S selectivity and capacity has been recommended. The effects of different application methods and its adaptability to commercial plants has been discussed.
