Description
Technical field
The present invention relates to environmental technology field, more particularly to waste mineral oil regeneration reducing method.
Background technology
Waste mineral oil is mainly derived from the productions such as the m of e processes such as machinery, power, transport, and industrial and mining establishment
The waste hydraulic oil of generation, used oil, waste lubricating oil, waste diesel, useless gear oil etc. in business process.Mineral oil is due to by external miscellaneous
The factor impacts such as matter is polluted, absorbs water, thermally decomposed, oxidation, lose original process based prediction model, form waste mineral oil, and it gives up
Liquid usually contains the impurity such as water, metal filings, dust, gravel, fibrous matter.Waste mineral oil contains multiple noxious substance, with
Meaning is toppled over and can be polluted air, water source and soil, destroys ecological environment, serious threat health safety.In the face of current
Global energy crisis, reclaims waste mineral oil, Reclaimed Base Oil, modulates all kinds of oil product, meets environmental protection and circulation warp
Ji demand for development, can create huge economic and social profit.
In prior art, mineral waste oil handling technique is mainly had pickling-hargil method, distillation-hargil method, distillation-add
Hydrogen method and membrane separation process etc..And using the conventional regeneration techniques such as hargil method, it is poor that early stage settles the pretreating effects such as remove impurity, regeneration
Oil loss is high, yield is low, and produces acid sludge, spent bleaching clay etc. and cause secondary pollution.And the forward position regeneration techniqueses such as membrane separation process, right
Oil requires harshness, and cost of investment is high, and treating capacity is little, it is impossible to meet large-scale production requirement.Thus, it is provided that one can be deep
The method and system of the oil products such as degree remove impurity, reclaiming one line, two wires base oil is the most necessary.
Summary of the invention
The technical problem to be solved in the present invention is to overcome drawbacks described above, it is provided that a kind of to environment without any pollution, and can be again
The waste mineral oil regeneration reducing method of the raw former index oil product being reduced to high-quality.
For solving the problems referred to above, the technical solution adopted in the present invention is:
Waste mineral oil regeneration reducing method, comprises the following steps:
A, distillation, isolate moisture, gasoline component, diesel component, base oil, heavy oil；
B, prepare molecular sieve catalyst, choose Y-type zeolite molecular sieve, 4A type zeolite molecular sieve and lewis acid, its quality
Ratio is: (1.6-2.5): (2.0-3.0): (5.0-6.0), by the Y-type zeolite molecular sieve chosen, 4A type zeolite molecular sieve and Louis
This acid is baking mixed, sintering temperature 400 DEG C to 600 DEG C, roasting time 5 hours to 7 hours；
C, go the removal of impurity, base oil adds molecular sieve catalyst, malonic anhydride and purity titanium tetraethoxide at normal temperature and pressure
Under be sufficiently mixed 2 hours to 3 hours, the mass ratio of base oil, molecular sieve catalyst, malonic anhydride and purity titanium tetraethoxide is: 100
∶(1.5-2.5)∶(0.8-1.5)∶(1.0-2.0)；
D, filtration, separate the molecular sieve catalyst in step C product, it is thus achieved that finished product base oil；
E, storage, store the finished product base oil obtained in step D.
Improve as one: the molecular sieve catalyst filtered to isolate in step D is purged, by molecular sieve catalyst
In duct, attachment separates.
Improve as one: use hot nitrogen purging molecular sieve catalyst, by attachment band in molecular sieve catalyst duct
Enter in water, collect and dry.
Owing to have employed technique scheme, the present invention has the following advantages
1, waste mineral oil regeneration reducing can become the base oil index used by original mineral oil product, oil quality is high；
2 and do not have refuse to discharge in implementation process, each step products all be capable of recycle；
3, major part step is carried out at normal temperatures and pressures, it is not necessary to the equipment of capital intensive, and energy resource consumption is also few.
Below in conjunction with embodiment, the invention will be further described.
