  • 摘要: 为探索用于废润滑油再生吸附的廉价高效吸附剂，用粉煤灰作为吸附剂对废油进行吸附处理。配制一定浓度的以水为吸附质的模拟废润滑油，考察模拟废油的优化均匀实验条件及吸附过程中的动力学特性。结果表明：反应55 min时，吸附达到平衡，水的去除率达到91.15%，单位吸附量达到279.745 μg·g-1，对废油有较好的吸附效果；动力学数据拟合吸附过程符合准二级吸附速率方程；动边界模型分析得孔隙扩散和吸附反应为吸附过程的速度控制步骤；采用Dünwald-Wagner公式法，估算有效扩散系数（Dc）为7.271×10-7 cm2·s-1。
    Abstract: To explore the low-cost and efficient adsorbents used for waste lubricating oil regeneration by adsorption, fly ash was chosen as an absorbent to regenerate waste oil. Simulation waste oil with the unique adsorbate of water in a range of concentrations was made, and optimum experimental conditions were selected. Experimental results revealed that fly ash had an enhanced adsorption ability for treating water in simulation waste oil, with an adsorption equilibrium time of 55 min, 91.15% removal rate of water, and an equilibrium adsorption capacity of 279.524 μg·g-1. Linearizations of the different kinetic equations showed that the adsorption process was in line with a pseudo secondary kinetic equation. A moving boundary model analysis showed that the adsorption rate of water was mainly governed by pore diffusion and the adsorption reaction itself. With the linearization of the Dünwald-Wagner formula, the estimated effective diffusion coefficient (Dc) was 7.271×10-7 cm2·s-1.
