摘要： 为提高现有高分子聚合物原油破乳剂的性能和拓宽纳米材料的应用范围,以硫酸铝和氨水为原料,
运用溶胶凝胶法在纳米Al2O3 生成过程中与高分子聚醚破乳剂TA1031进行接枝改性,运用红外光谱仪、电镜、粘
度计和界面张力仪分析所制备的改性破乳剂。结果表明,将纳米Al2O3 复合于原油聚醚破乳剂中能取得比较好的
效果,破乳性能均比原破乳剂有很大的提高。当纳米Al2O3 与TA1031的质量比为1∶10时,所得到的改性破乳剂
效果最好,能将破乳率提高20%~25%,而且破乳脱水时间也能大幅度缩短。并对改性破乳剂的形成机理和破乳机
理做了初步分析。

Abstract: In order to improve the performance of macromolecule polymer demulsifier and enlarge the range of application of nano-material, the nano-Al2O3 and macromolecule polyether demulsifier TA1031 were grafted by sol-gel method with Al2(SO4)3 and NH3·H2O. The Nanometer modified demulsifier was analyzed by FTIR, SEM, rotational viscometer and interfacial tensionmeter. The results show that applying nano-Al2O3 to crude oil polymer demulsifier would greatly improve the performance of the original demulsifier. When the mass ratio of aluminium oxide and TA1031 was 1∶10, the performance of the nanometer modified demulsifier is better, and the ratio of demulsification would be improved about 20%~25%. The time of demulification and dewatering would be greatly shorten, and the demusification mechanism and formation mechanisms of nanometer modified demulsifier was preliminary analysised.
