Medium with worse lubricating property, such as light fuel oil, heavy fuel oil, coal tar, asphalt, viscose, emulsified mixture, etc. 润滑性较差的介质,如轻质燃油、重质燃油、煤焦油、沥青、粘胶液、乳化液等;
In light of the situation of the instruments used in the intensive processing of coke tar, some problems that need to be solved in the centralized upgrading of the instruments are discussed. 针对焦油深加工仪表使用中的情况,探讨了集中改造需要解决的几个问题。
Efficiency Analysis of Light Coal Tar in Heating of Pumping Stations 煤焦轻油在输油站加热中的效能分析
Improvement on Process of Removing Naphthalene from Coke Oven Gas During Primary Cooling and Final Cooling by Light Tar 煤气初终冷轻焦油洗萘工艺的改进
The results show that the additions of HDPE and PP increase the yields of aliphatic hydrocarbons in tars. The remarkable increase of hydrocarbons and light compounds makes the tar be used as feedstocks for production of hydrogenated gasoline. 结果表明:添加HDPE、PP使煤焦油中脂肪烃的相对收率提高,焦油中脂肪烃的含量明显增加和轻质化,可作为加氢精制汽油的原料;
New Processing Method for Washing Naphthalene Used of Light Tar 轻质焦油洗萘新工艺
Results that the light components has a lager proportion in the tar at lower and higher pyrolysis temperature indicated that tar components tend to be distributed in both low boiling point region and high boiling point region at high pyrolysis temperature. 在温度较低和较高时,焦油中轻质组分含量比例较大,说明温度较高时,焦油组分趋于向低沸点和高沸点两侧范围集中分布。
FT-IR shows that, through supercritical extraction, it can make lots of high value-added products accumulate in light oil components, which is helpful for further processing utilization of coal tar. FT-IR表明,通过超临界抽提,可以使大量高附加值产品在轻油组分中得以富集,有利于煤焦油进一步的加工利用。
