加氢柴油光安定性能

The Light Stability of Hydrogenated Dies el

加氢生成油 (尤其加氢柴油 )对光比较敏感 ,光照后油品颜色变黑 ,产生沉淀。主要原因是加氢生成油中的荧光性物质对光的安定性较差。文章分析了荧光产生的原因和荧光物质的结构以及加氢工艺条件和催化剂的化学组成对产生荧光物质的影响 ;介绍了避免产生荧光性物质和脱除光不安定因素的几种方法。

Hydrogenated oil (esp .hydrogenated Diesel) is prone to blacke n and form deposit under the light.The f luorescence in oil is the main cause to poor stability of hydrogenated oil und er the light.This article discusses the molecular structure of the fluorescence, the effects of processing conditions of hydrogenation and chemical composition o f catalysts of the occurrence of fluores cence.It describes a few methods to avoi d the occurrence of fluorescence and to get rid of the unstability of oil under the light.
