3_十四烷氧基_2_羟丙基三乙基氯化铵在大庆油砂表面吸附性能

摘要季铵盐由于其良好的性能，日益受到人们的重视，在油田、食品和日用化工等领域已得到广泛的应用。研究了地层温度下(45 ℃)，3十四烷氧基2羟丙基三乙基氯化铵(TPAC)在大庆油砂表面的静态吸附性能，考察了液固比、吸附时间和浓度对静态吸附量的影响。结果表明，TPAC溶液在大庆油砂表面达到静态饱和吸附时：液固比为20∶1；浓度为1.84 mmol/L；吸附时间为6 h，吸附等温线为S型曲线。当TPAC的浓度达到1.10 mmol/L时，形成单分子层饱和吸附；当浓度增加至1.84 mmol/L达到双分子层饱和吸附，饱和吸附量为13.21×10^-6mol/g。研究季铵盐吸附性能为季铵盐在油田中的应用打下良好的基础。

Abstract： People pay more and more attention to quaternary ammonium salt for its good performance. Quaternary ammonium salt has been widely applied in oil field, food and daily chemical field. Capability of static adsorption of TPAC on the surface of Daqing oil sand under formation temperature (45℃) was studied, and the influence of liquidsolid ratio, adsorption time and concentration were discussed. The results show that when the adsorption of TPAC is saturated on the surface of Daqing oil sand: ratio of liquid to solid is 20∶1, concentration is 1.84 mmol/L, adsorption time is 6 h. The absorption isotherms is Sshaped curve. When the concentration becomes 1.10 mmol/L, it can form saturated monolayer adsorption membrane; and when the concentration becomes 1.84 mmol/L, it can form saturated bilayer adsorption membrane with a saturated adsorption quantity of 13.21×10^-6 mol/g. The study of the adsorption capacity of quaternary ammonium salt will have a good base for its application in oil field.
