Description
Technical field
The present invention relates to waste lubricating oil and process recovery technology field, particularly relate to a kind of preparation method of wilkinite lubricating oil flocculation agent.
Background technology
Petroleum products in use usually produces some waste lubricating oils, mainly the waste lubricating oil changing in power lubrication process, as the waste hydraulic oil of changing on the devices such as transmission, cooling, thermal treatment, transformer oil, quenching oil and a large amount of filthy wet goods of starting a machine and washing parts.The refuse that these waste oil Chang Zuowei is useless is outwelled or is treated as fuel and burns, and not only the energy is caused to significant wastage, but also environment is caused to severe contamination.Therefore waste lubricating oil being regenerated and had very important meaning, is first save energy, turns waste into wealth, and is conducive to making full use of of petroleum resources, is to be secondly conducive to prevent the pollution of the environment, and avoids soil, waters is contaminated and maintaining ecological balance etc.In fact, from lubricating oil degradation mechanism, analyze, the so-called waste lubricating oil of the overwhelming majority is not really scrapped, the wherein part hydro carbons that goes bad just of oil product, accounts for 10%～25%, and all the other most of hydrocarbon compositions are still main viscosity carrier and the effective constituent of lubricating oil, method by physics or chemistry is removed waste oil mesometamorphism dirt and impurity, just waste lubricant oil regeneration can be become to the satisfactory base oil of quality, after allotment additive, just can obtain superior in quality processed oil.
Waste lubricant oil regeneration is the means of a kind of save energy of being widely adopted, and rotten lighter lubricating oil is as long as can recover its original quality through physical cleaning processes such as precipitation, filtration, dehydrations; Rotten serious lubricating oil, needs to remove the acids, phenols and the colloid that generate after rotten, bituminous matter etc. through chemical refining, then supplements the additive of some amount, also can become the lubricating oil reusing.If purifying regeneration processing condition are proper, the waste lubricant oil regeneration with crossing can be become to quality completely and approach or reach new oil standard and well behaved lubricating oil.
The waste lubricating oil treatment process of prior art all produces a large amount of acid sludges and waste water, reach the object of clean regeneration, will reduce the generation of acid sludge, or acid sludge is fully utilized.
Bentonitic essential mineral composition is montmorillonite.The crystalline structure of montmorillonite belongs to 2:1 type, i.e. each one deck silicon-oxy tetrahedron up and down, and therebetween one deck alumina octahedral, interlayer connects by Van der Waals force, and water molecules easily enters in structure cell.In silicon-oxy tetrahedron and alumina octahedral, silicon ion and aluminum ion can be by other ion exchanges at a low price, thereby produce permanent negative charge, cause wilkinite surface charging, and there is stronger adsorptivity and cationic exchange, for bentonitic sodium, organic-treating provide condition.
