摘要

以焦化柴油和催化柴油加氢精制混合柴油作为原料,在一定条件下,考察了不同类型固体吸附剂对柴油脱色脱碱性氮的效果。静态实验结果表明,活性炭吸附剂的脱色效果最好,ASTM D1500色度达到0.2;硅酸铝吸附剂的脱碱性氮效果最好,脱除率达到90%。动态实验结果表明,活性炭吸附剂的胶质饱和吸附量最高,达到5.58%,但碱性氮饱和吸附量仅有0.45%。硅酸铝吸附剂的脱碱性氮效果最好,碱性氮吸附容量为0.91%,碱性氮饱和吸附量达到1.24%。与新鲜剂相比,采用高温焙烧再生,活性炭吸附剂能够完全恢复脱色脱胶质能力;采用极性溶剂再生,硅酸铝吸附剂能够完全恢复脱碱性氮能力。

Abstract

The mixed hydrogenation of coking diesel and catalytic diesel was used as raw material.Under certain conditions,the effect of different types of adsorbents on decolorization and debasing nitrogen of diesel oil was investigated.The results of static test showed that the decolorization effect of activated carbon adsorbent was best,ASTM D1500 chroma reached 0.2. Aluminum silicate adsorbent had the best effect of removing basic nitrogen and the removal rate reached 90%.Dynamic test results showed that the adsorption capacity of the activated carbon adsorbent was the highest,which reached 5.58%,but the saturated adsorption capacity of basic nitrogen was only 0.45%.The aluminum silicate adsorbent had the best effect of remov-ing basic nitrogen,the adsorption capacity of basic nitrogen was 0.91%,and the adsorption capacity of saturated nitrogen was 1.24%.Comparing to the fresh agent,using high temperature roasting and regeneration,activated carbon adsorbent could completely restore decolorization and gelatinization ability.Using polar solvent regeneration,aluminum silicate adsorbents could fully restore the ability to debase nitrogen.
