| 摘 要： | 通过正交实验，研究了γ-Al2O3载体制备中拟薄水铝石水洗的连续化。方差分析表明，第一阶段洗水的pH是影响脱氯效果的关键因素，初步得出水洗连续化的优化条件。与国内外传统的间歇式水洗相比，收率从80%提高到99.7%，所需洗水量仅为原来的1/3，而处理500 kg物料的生产周期也从10 h缩短到2～3 h。

| Abstract: | Continuous washing of pseudoboehmite instead of batch-wise washing for preparation of γ-Al2O3was tested using L27(313) orthogonal experiments. Variance analysis showed that pH of washing water was the key factor affecting chloride removal efficiency. Optimum condition for continuous washing was obtained. Compared with conventional batch-wise washing, the yield was enhanced from 80% to 99.7%, water consumption was lowered by two-thirds, and production cycle for processing 500 kg material was shortened from 10 h to 2-3 h. |
