Description

一种用于汽油的脱硫吸附剂
技术领域
本发明属于汽油脱硫技术领域，具体涉及一种用于汽油的脱硫吸附剂。
背景技术
汽油中硫化物的存在形式有硫化氢、硫醇、硫醚、二硫化物、噻吩、二硫化物、噻吩及其衍生物。这些硫化物不仅会导致汽油氧化安定性变差、辛烷值下降和发动机燃系统的腐蚀，而且燃烧后生成的硫氧化物是大气污染的主要污染物。随着世界各国对于环境问题的重视，车用汽油中的硫所造成的污染问题已经越来越受到关注。吸附法用于汽油脱硫时，吸附剂可以选择性地脱除汽油中的芳烃类含硫化合物，而且对于汽油中的烯烃无影响，避免了加氢精制过程中，为保证脱硫效果而造成的大量烯烃被加氢饱和，致使汽油辛烷值下降的问题。正因为如此，吸附脱硫方式的应用越来越引起人们的关注，成为国内外各大石油公司研究与开发的重点课题之一。

将上述各物质制成本发明的方法是：
1）将活性炭浸渍高锰酸钾进行氧化处理，浸渍时间30-50分钟；
2）将步骤1）中的氧化处理后的活性炭与凹凸棒土和水滑石混合，制得混合颗粒；
3）将步骤2）中的混合颗粒加入氧化铝和氧化硅，搅拌均匀后进行焙烧，在氮气保护下400-480℃温度下焙烧1-5h既得。
本发明的有益效果是：本发明一种用于汽油的脱硫吸附剂操作简单，价格廉价；同时由于该吸附剂中含水滑石，可以针对硫化物分子对吸附剂的孔结构、尺寸以及酸碱性进行调节，可深度脱除汽油中的含硫化合物。
