Abstract

The invention relates to a deacidifying agent for base oil of crude lubricating oil and a preparation method of the deacidifying agent, and the deacidifying agent comprises a component A and a component B. The component A comprises the following components in parts by mass: 20-50 parts of aluminum oxide, 10-25 parts of calcium oxide, 2-5 parts of zinc chloride and 2-5 parts of magnesium chloride;the component B comprises the following components in parts by mass: 5-30 parts of ammonia water, 14-20 parts of caustic soda and 50-60 parts of water; wherein the NH3 content of the ammonia water isnot less than 20%; and the component C comprises the following components in parts by mass: 12-20 parts of activated carbon, 10-20 parts of modified montmorillonite and 5-10 parts of modified carclazyte. The invention is specially used for crude lubricating oil base oil regenerated and recovered from waste emulsion discharged in aluminum pop can production, so that the oleic acid value of regenerated lubricating oil base oil is reduced from 8-20 mg(KOH) / g to below 0.05 mg(KOH) / g, thereby reaching the technical standard of base oil; meanwhile, the deacidified base oil is clear and transparent and does not contain soap gel.

Description

technical field [0001] The invention belongs to the technical field of waste lubricating oil treatment, and in particular relates to a deacidifying agent for crude lubricating oil base oil and a preparation method thereof. Background technique [0002] Lubricating oil is composed of lubricating base oil plus detergent and dispersant, anti-oxidant and anti-corrosion agent, extreme pressure anti-wear agent, oiliness agent and friction modifier, viscosity index modifier, rust inhibitor, pour point depressant, anti-corrosion Additives such as foaming agents are mixed. When the lubricating oil is used for a long time, it will deteriorate and age due to water, air, dust, metal and other pollution. The rancidity of base oil produces petroleum acid (naphthenic acid), which increases the acid value of base oil from 0.03mgKOH / g to 8mgKOH / g or even 20mgKOH / g. [0003] The acid value of regenerated crude base oil is corrosive, so deacidification of crude base oil is an essential and i...
