摘要:研究陽(yáng)離子表面活性劑十六烷基三甲基溴化銨(CTAB) 和驅(qū)油表面活性劑十二烷基苯磺酸鈉(SDBS) 復(fù)配體系的乳化能力和表面張力等相關(guān)性能,并研究溫度對(duì)復(fù)配體系的影響。實(shí)驗(yàn)結(jié)果顯示,當(dāng)陽(yáng)離子表面活性劑和驅(qū)油表面活性劑復(fù)配體系的質(zhì)量比為8:2時(shí),表面張力低至29.92 mN·m-1,此時(shí)具有較強(qiáng)的表面活性,且溫度的升高有利于表面張力的降低。實(shí)驗(yàn)結(jié)果還表明該表面活性劑復(fù)配體系對(duì)煤油的乳化能力較差,但CTAB和SDBS在乳化能力方面仍然存在增效作用。 關(guān)鍵詞:表面活性劑;復(fù)配體系;表面張力;乳化能力 急,幫幫忙啦! |

ABSTRACT: The combined system was composed by cationic surfactant of hexadecyl trimethyl ammonium bromide (CTAB) and surfactant for EOR of demulsifier dodecyl benzenesuifonate (DBSS) .The emulsify capability and surface tension properties were investigated . The influence of temperature to the system was also discussed. The result shows that the surface tension was declined to 29.92nN.m-1 and the system performed excellent surface activity when the mass ratio of CTAB and DTAB was 8:2 . The surface tension was decreased with the increase of temperature. In addition, this combined system shows poor the emulsify capability to kerosene, but improves the effect of that to CTAB and SDBS. Key words: surfactant; combined system; surface tension; emulsify capability 希望有幫助吧。等高手,虛心學(xué)習(xí) |
