Abstract
The processing method of Pyrolysis gas oil PGO upgrading of the present invention is that a kind of catalyzer that utilizes improves the Pyrolysis gas oil PGO method for quality, is to add AlCl in diesel oil
3Make it to produce polyreaction, thereby reduce the proportion of the unsaturated hydrocarbons in the Pyrolysis gas oil PGO, again the oil product after the polymerization is carried out decolorizing and refining, carry out fractionation by distillation at last, draw the diesel oil and the measured base oil of matter of colorless and odorless good stability.The technical process of the inventive method is simple, saves the energy, and is free from environmental pollution, is widely used.
Description
The present invention relates to the oil Refining Technologies field, belong to the processing technology that improves diesel quality, be suitable for reprocessing Pyrolysis gas oil PGO.
The catalytic cracking diesel oil that in to Crude Oil Processing, produces, coker gas oil and thermally splitting diesel oil, quantity is big, quality is low, can not sell as formal product.Because this diesel oil is brownish black, frowziness, impurity such as contained unsaturated hydrocarbons and gum asphalt are more, and the oil product instability can not prolonged preservation, and is not popular with users.
In order to improve the quality of Pyrolysis gas oil PGO, scientific research personnel both domestic and external for many years relatively pays close attention to this problem, once there was the people in Pyrolysis gas oil PGO, to add multiple auxiliary agent abroad, in the hope of improving quality, domestic R﹠D institution adds multiple additives in Pyrolysis gas oil PGO, in the hope of improving diesel quality, all do not obtain positive effect.At present industrial in order to improve diesel quality, be the method that adopts hydrogenation, but the complex process of this method, need to operate under High Temperature High Pressure, danger is very big, tooling device is required high, catalyzer is also relatively more expensive, also sources of hydrogen must be arranged, and general refinery is difficult to realize.
The objective of the invention is the research and utilization catalyzer, make Pyrolysis gas oil PGO carry out polyreaction, improve the processing method of Pyrolysis gas oil PGO quality.
The processing method of Pyrolysis gas oil PGO upgrading of the present invention, realize by following flow process: earlier Pyrolysis gas oil PGO is sent into reactor, add the aluminum trichloride catalyst that accounts for diesel oil weight 2-5% again, under normal pressure, temperature is controlled between 80-150 ℃, the agitator revolution is not less than 90 rev/mins, after carrying out polyreaction 6-8 hour, stopped reaction, cooling sedimentation 5-8 hour, at the bottom of still, discharge aluminium residual oil then, again the oil after the polymerization is squeezed in the refining kettle, and put into the calcium hydroxide that accounts for diesel oil weight 2-3% and the atlapulgite that accounts for diesel oil weight 3-5%, under normal pressure, temperature is controlled between the 80-130, the agitator revolution is not less than 90 rev/mins, the refining time was not less than 1 hour, oil after will making with extra care with pump 7 is then squeezed in the pressure filter and is filtered, and filter residue is entered in the groove by filter bottom, and filterable oil flows in the treated oil liquid collecting jar below the filter by liquid level pressure, boost with pump 8 again and squeeze in the decompression still, in still, under the condition of vacuum tightness greater than 740mmHg, carry out underpressure distillation, diesel oil is separated with base oil, temperature is lower than 300 ℃ of time-division distillate diesel fuels, and temperature fractionates out base oil when being higher than 300 ℃.
The advantage of the processing method of Pyrolysis gas oil PGO of the present invention:
1, process design is reasonable, and is simple, and polyreaction is thermopositive reaction, need not heat and other conditions, saves the energy, helps normally carrying out of polyreaction.
2, utilize this processing method to make to account for the unsaturated hydrocarbons of Pyrolysis gas oil PGO weight 80-90% to carry out polyreaction, the residual amount of bromine valency is not more than 1% in the diesel oil, owing to adopted Ca(OH)
2Acid AlCL has neutralized
3, adopted atlapulgite to decolour, efficient height not only, comprehensive yield can reach 90-95%, and quality is good, and diesel oil becomes tasteless transparent liquid, greatly reduces condensation point, has improved 16 alkane values, and good stability can use in standing storage, and base oil is also better.
3, this processing method is applicable to the diesel oil that various cleavage methods produce, catalytic diesel oil, and coker gas oil and thermo-cracking diesel oil are widely used.
Accompanying drawing is the process flow sheet of Pyrolysis gas oil PGO upgrading.
Respond among figure still 1, refining kettle 2, pressure filter 3, liquid collecting jar 4, decompression still 5, A is that Pyrolysis gas oil PGO inlet, B are that diesel oil outlet, C are the base oil outlet behind the upgrading, and D is AlCl
3Inlet, E is Ca(OH)
2, carclazyte inlet.
One cover Pyrolysis gas oil PGO upgrading production line has been installed according to the method described above, has been dropped into 10 tons of coker gas oils, added catalyst A lCl
3500Kg, 110 ℃ of temperature stir 90 rev/mins of number of times, carry out polyreaction 6 hours, the oil product after the polymerization is squeezed into refining kettle, adds Ca(OH)
2300Kg, atlapulgite 500Kg, temperature is controlled at 120 ℃, stir 90 rev/mins of number of times, make with extra care and filter after 7 hours, squeeze into the decompression still again, vacuum tightness during distillation is not less than 740mmHg, and fore-running gets 6 tons of diesel oil below 300 ℃, distillation temperature is greater than 300 ℃, get 3 tons of base oils, diesel oil water white transparency, tasteless, 16 alkane values, condensation point all improve, steady quality, but standing storage.
