用流动微量量热法研究了十二烷基硫酸钠(SDDS)和十二碳羧酸钠(SL)在克拉玛依油田九区和乌尔禾区油砂上的吸附,简要地计论了吸附机理。所得实验结果表明,SL 在油砂上的吸附强度比 SDDS 的要大,在相当低的浓度下即可迟到饱和吸附。
The adsorption of sodium dodecyl sulfate (SDDS) and sodium dodecyl carboxylate (SL) on oil sands in the 9th and the Wuerhe areas of Karamay Oilfield was studied by flow microcalorimetry. The adsorption mechanism was briefly discussed. The experimental results show that the adsorption strength of SL on oil sands is larger than that of SDDS, and can be saturable late at a relatively low concentration.
