| titleOfInvention | Waste engine oil purifying agent and purification and regeneration method of waste engine oil |
| abstract | A used oil purifying agent and its purifying and regenerating method are disclosed, which contains H 2 O 2 、O 3 And organic acid solution H 2 O 2 、O 3 And the molar ratio of the organic acid solution is 5-30: 5-30: 50-90; the organic acid solution is a composite organic acid solution with the pH value of 1.5-5.5; 50% -95% of the composite organic acid solution is organic acid containing at least two carboxyl groups; the purifying agent is composed of H 2 O 2 、O 3 And the composite organic acid solution is fully mixed at the temperature of 20-35 ℃. The purifying agent of the invention adopts H 2 O 2 、O 3 And organic acid solution, wherein H is 2 O 2 、O 3 The catalyst is mainly used for catalytically oxidizing organic compounds such as sulfur, nitrogen and the like in the waste engine oil, improving the polarity of the organic compounds and promoting the organic compounds to migrate from an oil phase to a water phase. The organic acid solution provides an acidic environment, and the decoloring efficiency is improved. The purification and regeneration method of the invention fully utilizes the purified engine oil generated in the decolorization reaction and the acid water removed from the waste engine oil for cyclic utilization, and is environment-friendly and safe. |
