Description
Technical field
The present invention relates generally to contain high quality asphalt (asphalt) of pitch (pitch) and preparation method thereof, described pitch makes as the by product of solvent deasphalting process, more particularly, the present invention relates to wax content and thin film oven test ductility afterwards and obtain improved high quality asphalt, described improvement is to mix with pitch by the vacuum residuum with routine to reach, described pitch has the chemical constitution of control, by using solvent deasphalting unit, make with the mixture that is similar to the petroleum distillate of long residuum by comprising long residuum, the invention still further relates to the method for the described high quality asphalt of preparation.
Background technology
According to using vacuum distillation plant as shown in Figure 1 to prepare the bituminous ordinary method, the long residuum that uses crude unit to make is carried out vacuum distilling to be handled, have controlled infiltrative vacuum residuum with separation, then this vacuum residuum is directly made pitch.
The pitch that makes like this is as pavior.Should consider the bituminous important properties equally, for example the ductility after perviousness, penetration index, softening temperature, viscosity, wax content and the thin film oven test.In these character, the metric perviousness as pitch hardness should fundamentally satisfy, so that pitch is used as pavior.In addition, when estimating the bituminous quality, mainly consider wax content and thin film oven test ductility afterwards.For this reason, along with reducing and thin film oven test ductile increase afterwards of wax content, think that the bituminous quality improves.
When vacuum residuum is directly made bituminous, to be suitable for preparing bituminous crude oil group selection combine, provide it to crude unit then, use vacuum distillation plant to control the separation temperature of vacuum residuum then, to obtain required perviousness.In addition, other main character can be depending on the crude oil that is conveyed in the crude unit.Therefore, have high ductility after the test of low wax content and thin film oven, must carry out appropriate selection the group of the crude oil in crude unit, handled in order to prepare.Yet,, may cause the undesirable negative impact of people to economic benefit because the price of crude oil accounts for a big chunk of refining plant technology cost.
In addition, directly prepare high quality asphalt by vacuum residuum and also can suffer following defective: because the vacuum gas oil that uses described vacuum distillation plant to make with vacuum residuum is used as the raw material of high value technology (for example hydrocracking and fluid catalytic cracking), therefore operating vacuum distillation plant with when guaranteeing asphalt quality, can make that comparatively the quality or the productive rate of expensive vacuum gas oil are very low, this be people do not wish to occur.About this point, the U.S. discloses and has disclosed a kind of use vacuum residuum or long residuum for 2004-163996 number as feedstock production bituminous method.
Simultaneously, the concrete chemical structure of considering to be used for directly preparing bituminous vacuum residuum, the chemical structure of described long residuum and vacuum residuum is made up of saturated compound, aromatic substance, resin and bituminous matter.To this, when the content of known saturated compound is very low, can obtain low wax content, when saturated compound with asphalt content is very low, when the content of aromatic substance and resin is very high, can obtain the ductility after the high thin film oven test.In vacuum distilling, because vacuum gas oil and vacuum residuum are separated from each other according to their separation temperature, so angle from chemical structure, be difficult to optionally to increase the amount of aromatic substance and resin in the vacuum residuum, to improve the ductility after the test of wax content and thin film oven.In addition, the chemical structure of described vacuum residuum can not only depend on crude oil.
Summary of the invention

A target of the present invention provides has good wax content and thin film oven test ductile high quality asphalt afterwards.
Another target of the present invention provides the method for this high quality asphalt of preparation.
Technical scheme
In order to finish above-mentioned target, the invention provides high quality asphalt, it comprises pitch, and described pitch is to make by the mixture that comprises first vacuum residuum and first petroleum distillate is carried out solvent deasphalting.
In addition, the invention provides a kind of method for preparing high quality asphalt, this method comprises carries out crude distillation and vacuum distilling, make and be used to prepare bituminous vacuum residuum, this method is used and is carried out the pitch that solvent deasphalting makes by the mixture to following component: vacuum residuum, and it makes by vacuum distilling; And first petroleum distillate, it is lighter than described vacuum residuum, comprises high-load aromatic substance and resin.
Description of drawings
In conjunction with the accompanying drawings, can more be expressly understood above-mentioned and other target of the present invention, feature and advantage by following detailed description, among the figure:
Fig. 1 is to use the vacuum residuum that is made by vacuum distillation plant to prepare the synoptic diagram of the ordinary method of straight-run pitch;
Fig. 2 is according to of the present invention, uses the mixture of the pitch that makes by solvent deasphalting and lightweight overhead product to prepare the synoptic diagram of the method for high quality asphalt.
Embodiment
To describe the present invention below.
According to above-mentioned preparation bituminous ordinary method, pitch is directly made by vacuum gas oil (VGO) and vacuum residuum (VR), described vacuum residuum (VR) is by using vacuum distillation plant (VDU), and the long residuum (AR) that uses crude unit (CDU) to make is carried out making after the vacuum distilling.Referring to Fig. 1, vacuum gas oil is carried out hydrocracking and fluid catalytic cracking, thereby be refined into kerosene and gas oil, and gasoline, described vacuum residuum is directly made pitch.
Yet, pitch according to the present invention comprises pitch, described pitch is by first petroleum distillate and first vacuum residuum are mixed, then this mixture being carried out solvent deasphalting (SDA) makes, described first petroleum distillate comprises the long residuum (atmospheric reside) that uses crude unit to make, and described first vacuum residuum is to use described vacuum distillation plant to make.Preferably, in order to control perviousness, described pitch and second vacuum residuum and/or second petroleum distillate are mixed, thereby make pitch.The pitch that makes like this has the ductility after splendid wax content and the thin film oven test.
Fig. 2 has shown a kind of method for preparing high quality asphalt of the present invention.As shown in Figure 2, first vacuum residuum that uses vacuum distillation plant to make is suitably mixed with first petroleum distillate that comprises described long residuum, then this mixture is carried out solvent deasphalting, obtain deasphalting oil and pitch.Described deasphalting oil carries out refining by hydrocracking and fluid catalytic cracking, and the described pitch and second vacuum resid and second petroleum distillate mix, and control its perviousness, thereby makes pitch of the present invention.
The ratio of mixture of described first vacuum residuum and first petroleum distillate is preferably 10-90 weight %.If this ratio is less than 10 weight %, then the effect of aromatic substance that comprises in first petroleum distillate and resin is very low.On the other hand, if this ratio surpasses 90 weight %, then deasphalting the time, the content of light oil can increase in the pitch, thereby makes the bituminous degradation.
In the present invention, for will mix with vacuum residuum, as the petroleum distillate of the raw material of solvent deasphalting process and final blending process, it also comprises the slurry oil (SLO) that the middle distillate vacuum gas oil (HCVGO) that makes by vacuum distilling and/or fluid catalytic cracking make except above-mentioned long residuum.
According to the present invention, should carry out solvent deasphalting in one way, make the perviousness similar (almost equal) of the perviousness of the pitch that makes by solvent deasphalting and vacuum residuum or a little less than the perviousness of vacuum residuum, thereby with described pitch itself, perhaps the mixture of pitch and vacuum residuum and/or petroleum distillate is converted into pitch.When blended bituminous perviousness is substandard, can further control perviousness by adding the cut lighter than vacuum residuum, for example can add long residuum, middle distillate vacuum gas oil, and/or slurry oil.
Mainly with C
3-C
6N-paraffin (paraffin) or isoparaffic solvent are as the solvent that is used for solvent deasphalting process.In addition, in order to control the perviousness of pitch, preferably use C
3-C
4Paraffin solvents or its mixture.In addition, the productive rate of pitch is along with long residuum and the ratio of vacuum residuum and the variation of operational condition as raw material, and this productive rate is about 10-90 volume % usually.When the pitch productive rate is very high, make and have the infiltrative soft work in-process product of high pitch, deasphalting oil properties obtains to improve.When the carbon number of solvent is very low, and the service temperature of solvent deasphalting process is very high the time, and the productive rate of pitch increases, so the absolute content of aromatic substance and resin is very high.Yet if the productive rate of pitch is too high, the infiltrative standard of asphaltic products. will be difficult to satisfy.In addition, the content of lightweight overhead product is very big, so the ductility after the thin film oven test may be because the promotion of the oxidation when carrying out the ductility measurement after the thin film oven test and variation.Therefore, it is important suitably to control the productive rate of pitch according to the raw material properties of described solvent deasphalting method.
In the present invention, test ductility afterwards and reduce wax content in order to improve thin film oven, solvent deasphalting process is preferably in the presence of n-propane, under 43-93 ℃ pitch extraction temperature, carry out, perhaps in the presence of normal butane/Trimethylmethane, under 115-150 ℃ temperature, in the 30-46 kg/cm
2The pitch of gram extracts under the pressure and carries out.
Following table 1 has shown the long residuum (AR) as raw material and the character of vacuum residuum (VR), and the deasphalting oil (DAO) that makes by the solvent deasphalting method, by above-mentioned mixtures of residua and the character of pitch.Can be clear that very that from table 1 because the saturated compound content of pitch is less than vacuum residuum, it should contain low wax component.In addition, the content of described aromatic substance and resin is very high, has realized good thin film oven test ductility afterwards.This is to be based on paraffinic hydrocarbons owing to be used for the solvent of solvent deasphalting, therefore has high chemically compatible saturated compound slightly by deasphalting separating of oil, aromatic substance and resin compound component with low affinity are insoluble to solvent, are transferred to pitch.
Therefore, according to the present invention, not only long residuum but also other petroleum distillate of comprising high-load aromatic substance and resin all with vacuum residuum as raw material, make saturated compound remove with the form of deasphalting oil, and aromatic substance and resin transfer are to pitch, make in bituminous character, obtain useful wax content and thin film oven test ductile cut afterwards.
