It is showed by research that its cetane value is so high that DME is perfectly suitable to be alternative fuel of diesel engine, and it is hopeful meeting the future stringent emission regulation of diesel engine because of its clean combustion.

The characteristics of biodiesel is low content of sulfur and aroma hydrocarbon, high content of oxygen, high cetane value and flash point, less hazardous exhaust gas.

它具有含硫量极低、芳香烃含量少、含氧量高、十六烷值高、闪点高和废气逸出少等优点。

Including: to increase the cetane value of the fuel reasonably by adding the Cetane improvers;

其中包括加入十六烷值改进剂适度提高燃油的十六烷值；

Through it, octane value of gasoline, cetane value of diesel oil, aromatics and sulphur contents in fraction oil can be calculated.

用此方法可以计算汽油的辛烷值、柴油的十六烷值、馏分油中芳烃和硫含量。

Cetane value of bio-diesel was improved by adding the improver.

The process is discussed to prepare cetane number LH& 91 type improver of diesel fuel, and the affection of raw material ratio, reaction temperature to the product purity and yield is inspected.

本文讨论了研制和生产LH&91型柴油十六烷值改进剂的工艺条件。考查了原料配比、反应温度对产物纯度及收率的影响。

It contains no gasoline distillate but its diesel yield and cetane number index are high relatively.

由于该原油无汽油馏分，但柴油馏分收率较高且其十六烷值指数较高。
