Abstract
The invention relates to additive LT which is prepared from 54 to 60g of triethylenetetramine, 24 to 32g of propylene oxide and 12 to 18g of 202 anti-oxidation and anti-corrosion agent which react at 120 to 130 DEG C. The acid value of recyclable oil 320 is reduced to 0.12mgKOH/g, and the tribology functions thereof are recovered and significantly better than those of original novel oil.
Description
Technical field
The present invention relates to the regeneration of waste lubricating oil, particularly a kind of additive LT of reclaiming waste oil film bearing oil 320.
Background technology
For reducing friction and wearing and tearing, China's consumption of lubricating oil reached 4,400,000 tons in 2003, was second-biggest-in-the-world country of consumption, estimated will reach 5,300,000 tons in 2010. and the ratio of estimating waste lubricating oil can not be lower than 45% of its consumption.From Sustainable development and environment protection meter, the .1935 that must regenerate rises, and generally adopts purifying method more both at home and abroad; But must not approve that so far it is not virgin state and a performance of recovering waste lubricating oil, and just recovers base oil virgin state and performance; Though it is not high that its requirement seems, its process is long, and expense is high; Can only recover the value of base oil at most, ensure and subsidy almost do not have economic and practical if can't restrain. do not find a kind of effective regeneration technological line and technology and theoretical thereof that can lower refining expense again and improve again the refining quality of lubrication oil so far as yet. purifying method is that all kinds of waste lubricating oils are focused on again. the present invention then replaces concentrating with classification; Replace refining again to add regenerated additive; Key is the exploitation regenerated additive, and this type of regenerated additive is wanted and can be worked in coordination with remaining chemicaladditives in the waste lubricating oil, produces the tribology effect jointly; Can interact with remaining aging by product in the waste lubricating oil again, eliminate its disadvantageous effect tribological property and other lubricities.
Kelmet oil 320 useless because of: acid number rises to 0.66mgKOH/g, severe overweight, the tribology function reduces bigger.
Summary of the invention
For the tribology function of recovering waste oil film bearing oil 320 with overcome the acid number severe overweight; The present invention proposes a kind of additive LT of reclaiming waste oil film bearing oil 320; It is characterized in that with triethylene tetramine 54-60g propylene oxide 24-32g and 202 oxidation and corrosion inhibitors (unified code name is that T202-sees: Sinopec's product complete works is P.440) 12-18g is reacted at 120 ℃-130 ℃. press in the reclaiming waste oil film bearing oil 320; Containing the weight of anhydrating with the waste oil film bearing of slag oil 320 is 97%; The weight that contains additive LT is 3% mixed, and stirring at room 20min can make waste oil film bearing oil 320 obtain regeneration.
The acid number of the waste oil film bearing oil 320 after the regeneration is reduced to 0.12mgKOH/g by 0.66mgKOH/g; Its tribology function has not only obtained recovery simultaneously; But also significantly be superior to former fresh oil, thereby broken through the performance of countries in the world base oil that generally adopt, that can only recover waste lubricating oil so far first and under best situation, can only recover the regeneration usefulness of purifying method again of the value of base oil. simultaneously, also broken through and invested in integrated mill; Adopt the mode of large-scale regeneration specific equipment regeneration waste lubricating oil; Because the process with regenerated additive regeneration waste lubricating oil is very simple, both need not large-scale special equipment, again non-environmental-pollution; Thereby user's waste lubricating oil of can regenerating voluntarily, thereby can directly a large amount of reuse waste lubricating oils with cut down expenses.
Embodiment
Following examples but the invention is not restricted to following examples in order to explanation the present invention.
Embodiment 1.
With triethylene tetramine 57g, propylene oxide 28g and 202 oxidation and corrosion inhibitors (unified code name is that T202-sees: Sinopec's product complete works P.440) 15g is reacted into additive LT at 125 ± 2 ℃; Press then in the reclaiming waste oil film bearing oil 320, containing the weight of anhydrating with the waste oil film bearing oil 320 of slag is 97%, and the weight that contains additive LT is 3% mixed; Then at stirring at room 20min; Can make waste oil film bearing oil 320 obtain regeneration, the acid number of waste oil film bearing oil 320 is reduced to 0.12mgKOH/g from 0.66mgKOH/g; The tribology function has not only obtained recovery; And significantly be superior to former fresh oil: frictional coefficient has reduced 9.62% than former fresh oil, and wearing and tearing have reduced 41.83% than former fresh oil, and supporting capacity (PB) has improved 86.89% (seeing the tribological property table of fresh oil, waste oil, recovered oil for details) than former fresh oil.
The tribological property of fresh oil, waste oil, recovered oil relatively
Annotate: waste oil has anhydrated and slag
