单相金属间化合物SbSn的制备、表征及其对原油降黏

通过机械合金化（球磨法）制备金属间化合物SbSn，采用XRD、DSC、XPS等一系列分析手段对其相结构、熔点和表层元素的价电子态进行表征。实验在外加电场的情况下，以负载在丝网上的SbSn为吸附剂，考察静态法对原油乳状液的降粘效果。结果表明，以W（10）/O（90）为例，水浴温度恒定在20℃下，在表面活性剂用量为0.17%～0.20%，反应时间在8h后，电压规定在6.84V下，实验测定原油乳状液的粘度从8500mPa•s降低到3000mPa•s，推测可能原油乳状液中的极性物质在电流的诱导下与SbSn的表层发生化学吸附。

Preparation, characterization and viscosity reduction for crude oil of single-phase SbSn intermetallic compound

A SbSn intermetallic compound was prepared via mechanical alloying（ball milling）.The bulk phase structure, melting point and valence electron state on the surface layer were detected by XRD, DSC and XPS.Using SbSn supported on wire net as adsorbent, reducing viscosity behavior for crude oil emulsion was investigated through the static method under electric field.When the temperature was maintained at 20℃, the surfactant addition was 0.17%—0.20%, reaction time was over 8 h, voltage was assigned at 6.84 V,the viscosity of emulsion with W (10)/O (90) decrease from 8500 mPa·s to 3000 mPa·s determined with rotation viscometer.It was hypothesized there was electrochemistry reaction between polar matter in emulsion and SbSn surface under electric current induction.
