摘要：

按照小试制备的工艺条件放大生产了600 kg SQ112脱含氧化合物剂，并将其用于脱除异丁烯中的微量含氧化合物杂质；在1 L的工业侧线装置上，考察了SQ112脱含氧化合物剂在室温条件下的脱二甲醚情况以及再生性能。侧线试验结果表明：SQ112脱含氧化合物剂在0.6 MPa、1 h ^－¹、室温的条件下，将异丁烯中的二甲醚含量从1200～1300 mg/L降至小于2 mg/L，达到了聚合异丁烯的工艺指标，二甲醚的穿透吸附容量约5%，净化后的乙烯中没有其它副产物生成，该吸附剂可以再生，并且再生性能良好。

Abstract:

600 kg SQ112 oxygenate scavenger were prepared by scaling up laboratory test and used for removal of trace oxygenate in isobutene in a 1L fixed-bed reactor with industrial side stream feedstock. The performance of removing dimethyl ether in isobutene and its regeneration at room temperature were studied. The result showed that under 0.6 MPa，liquid space velocity 1 h^－1 and room temperature，the oxygenate scavenger SQ112 could remove dimethyl ether from 1200—1300 mg/L to less than 2 mg/L in isobutene，meeting the specification of polymer grade isobutene. The penetration adsorption capacity of SQ112 for dimethyl ether was about 5%. No byproduct was found in the isobutene after deoxygenation. This adsorbent could be regenerated and the performance was good after regeneration.
