考察了9种结构明确的烷基苯磺酸盐经五种分布形式复配得出的五种相对分子质量的复配烷基苯磺酸盐在大庆油砂上的吸附,探讨了温度、盐、碱、醇加量对复配烷基苯磺酸盐体系在大庆油砂表面吸附量的影响。结果表明,复配体系在油砂表面的吸附量随着温度的升高而降低,随NaCl、Na2SO4浓度的增加而增加,随MgSO4浓度的增加先缓慢增加后有所降低,随NaOH和Na2CO3含量的增加而增加,随着NaHCO3和KHCO3含量的增加而降低,随着醇浓度及醇碳链的增加而逐渐降低;异丁醇对复配体系在油砂表面吸附的影响依次大于叔丁醇、正丁醇。图10表1参10
The adsorption properties of the alkyl aryl sulfonates compounds(AASC),obtained by mixing 5 alkyl aryl sulfonates in the different distributions,on the Daqing oil sands were measured,and the effects of the temperature,the content of the inorganic salts,alkalis and alcohols on the adsorption of the AASC on the oil sands of Daqing were discussed.The results showed that the amount of adsorption of AASC decreased with increasing temperature,increased with the increasing NaCl、Na2SO4 concentration,firstly increased slowly and then decreased with the increasing MgSO4 concentration,increased with increasing NaOH and NaCO3 concentration,decreased with increasing NaHCO3 and KHCO3 concentration,gradually decreased with the increasing alcohols concentration and alcohols carbon chain.The effect of butanol on adsorption of AASC was arranged as follows: isobutanol tertiary butanoln-butyl alcohol.
