摘 要: | 对废汽油机油再生工艺进行了考察,结果表明:电脱盐脱钙和白土吸附不适合废汽油机油的预处理,蒸馏-加氢工艺适合废汽油机油再生;再生油满足VHVI 5润滑油基础油性能指标要求,其中润滑油馏分(大于360℃)收率为77.09%,蒸馏塔塔底残渣在现有的90号沥青产品中添加量3%时仍可以满足90号JTG F40—2004道路沥青标准,添加量5%时满足110号JTG F40—2004道路沥青标准。该方法润滑油回收率高,产生的废渣得到利用。

TEST OF REGENERATION PROCESSES OF WASTE GASOLINE ENGINE OIL |
| |
Abstract: | Regeneration processes of used gasoline engine oil were investigated. The results show that the methods of electric desalting and clay adsorption for waste oil decalcification are not suitable. While the base oil on specification can be obtained by distillation-hydrotreating process. The regenerated oil meets the lubricating base oil standard of VHVI 5 with a yield (>360 ℃ fraction) of 77.09%. When the addition of the distillation residue is 3% in 90# asphalt product, the load asphalt in compliant with 90# JIG F40-2004 standard can be produced. Increasing the dope of residue to 5%, 110 load asphalt, meeting 110# JTG F40-2004 standard, can also obtained. It is concluded that the distillation-hydrotreating process is suitable for regeneration of waste lube oil with high recovery of base oil and utilization of distillation residue. |
