EH-4丙烯专用COS水解催化剂的性能评价

The Research of EH-4 Hydrolysis Catalyst for Liquid Propylene

介绍了一种新型丙烯专用COS水解催化剂,研究结果表明,在12-50℃之间,EH-4型催化剂脱除COS的 活性明显优于A样品,对COS的转化率达99.3％-99.7％,比A样品提高10％-20％;出口COS精度达0.04×10-6。 EH-4型催化剂能广泛应用于液相丙烯精脱硫。

The paper introduces a new hydrolysis catalyst for liquid propylene. The result shows that under 12-50℃, EH-4 hydrolysis catalyst has superiority over sample A on removing COS: its COS conversion rate can reach 99. 3% ?99. 7% , which raises 10%-20% than that of sample A. And its outlet COS content is 0. 04 ×10-6. EH-4 hydrolysis catalyst can widely be applied in fine desulfurization of liquid propylene.
