Embodiment 1
[0020] Embodiment 1, the auxiliary raw material for improving the quality of the finished product after the regeneration of waste lubricating oil includes 80% to 85% of organic alkalis, 1% to 5% of inorganic alkalis, and 5% to 10% of caking Dispersant, 1% to 5% of adsorbent and the balance of co-solvent.
Embodiment 2
[0021] Embodiment 2, the auxiliary agent for improving the finished product quality after the regeneration of waste lubricating oil comprises 80% or 85% of organic bases, 1% or to 5% of inorganic bases, 5% or 10% of caking Dispersant, 1% or 5% adsorbent and the balance of co-solvent.
[0022] Organic bases and inorganic bases are blended, bonded and interacted to effectively reduce the content of unsaturated substances such as olefins and alkynes in waste engine oil. It can neutralize acidic substances in waste engine oil, such as a small amount of mercaptans, aldehydes, ketones and other acidic substances in waste engine oil, so that the acid value of the finished base oil can be effectively reduced, and a small amount of adsorbent can be added to effectively absorb colloids in waste engine oil , asphaltene and other organic impurities, reduce the oil cracking reaction caused by colloids and asphaltene in waste engine oil during processing, and eliminate the production of lig...
Embodiment 3
[0024] Embodiment 3, as the optimization of embodiment 1 and embodiment 2, organic bases are quaternary ammonium bases; or / and, inorganic bases are inorganic sodium alkali salts or inorganic potassium alkali salts; or / and, bonding dispersion The agent is modified bentonite or activated bentonite; or / and, the adsorbent is activated carbon or activated clay; or / and, the cosolvent is carbonamide. The solubility and alkali value of quaternary ammonium base are the best, which is most suitable for the present invention; modified bentonite and activated bentonite have large pore size, and fine particles are easy to suspend; activated carbon and activated clay both have large pore size and fine particle characteristics, and the adsorption effect Good; carbonamides have good hydrophilicity and lipophilicity.
