摘    要:利用静态吸附实验研究了实验室自制的三种高纯度十四烷基芳基磺酸盐在大庆油砂上的吸附规律,并考察了吸附时间,吸附温度及磺酸盐、NaCl、NaOH、正丁醇的浓度对吸附量的影响.结果表明:吸附量随着磺酸盐浓度的增大逐渐增加后趋于平稳,随着吸附温度和正丁醇体积浓度的降低、NaCl 和NaOH浓度的增加而增大; 磺酸盐活性剂的三种同分异构体中,随两部分碳链长度趋于均等,吸附量下降,且受助剂的影响变小.吸附热力学研究表明,十四烷基芳基磺酸盐在油砂上的吸附等温线服从Langmuir 等温方程,并且计算得到的各参数均能很好地反映磺酸盐在油砂上的吸附特征.吸附动力学研究表明,Elovich 方程能够更好地描述吸附量随时间的变化情况.

关 键 词:烷基芳基磺酸盐  助剂  固/液吸附  吸附热力学  吸附动力学

Abstract:Three tetradecyl aryl sulfonates of high purity were synthesized.Their static adsorption performance on oil sand from the Daqing oilfield was studied and the influence of adsorption time,adsorption temperature,concentrations of sulfonate,NaCl,NaOH,and n-butyl alcohol on the efficiency of adsorption were investigated.The experimental results show that with an increase in the concentrations of the sulfonates the adsorption capacity initially increased and then remained constant.The adsorption capacity increas...
Keywords:Alkyl aryl sulfonate  Additive  Solid/liquid adsorption  Adsorption thermodynamics  Adsorption dynamics
