功能化酸性离子液体脱除模拟油品中的非碱性氮
, PP. 55-60
Keywords: 功能化,酸性离子液体,脱氮,非碱性氮,吲哚
Abstract:
？合成了一系列功能化酸性离子液体并用于模拟油品中非碱性氮-吲哚的脱除。结果表明，离子液体的阴离子对脱氮率有较大影响，离子液体的酸性越强，对吲哚的选择性脱除效果越好，不同阴离子的脱氮率顺序为：hso4->cf3coo->h2po4->ch3coo-。以（ch3ch2）3n（ch2）3so3hhso4为例，考察了剂油比、剂水比、沉降时间、反应时间和温度对油品脱氮率的影响。结果表明，在优化的工艺路线下，（ch3ch2）3n（ch2）3so3hhso4对油品中的吲哚脱除率可达99.12%，重复使用六次后，脱氮活性未见明显降低，具有良好的稳定性，。
