Comparative example 1
For illustrating the utility model high softening point bitumen and its continuous producing method and system.
High softening point bitumen continuous process system：Laser heating feed arrangement is not provided with, vertical response kettle is with reference to embodiment
1, difference lies in replace material conveying assembly, which includes axially setting along the vertical response kettle using agitating device
The supporting rod and the spiral-distributed stirring band of the circular supporting rod put；Actuating unit (motor) setting of the supporting rod
In the top of the vertical response kettle, in the upright projection of the vertical response kettle, the width of stirring band (helixangleβ is 75 °)
Degree (width for being located at supporting rod side) is the 1/2 of the vertical response kettle radius；
The continuous producing method of high softening point bitumen：Aforementioned asphalt stock is led to and is directly added in vertical response kettle,
Temperature is followed successively by 400 DEG C, 405 DEG C and 410 DEG C in three heating zones in vertical response kettle from top to bottom, and reaction pressure is
0.5MPa, the residence time of material is 8h, and the velocity of rotation for stirring band is 150rpm, obtains high softening point bitumen D1.
Test case
It will as follows be tested as the high softening point bitumen prepared by previous embodiment 1-3 and comparative example 1：
Softening point：With reference to method in ASTM D3104-2014, the softening point for measuring 5 points in high softening point bitumen is made even
Mean value；Softening point variance is to be calculated to obtain according to 5 points of aforementioned measurement；
Residual carbon content：With reference to JB/T 6774-2006 coal tar pitch fixed carbon assay methods；
Content of ashes：With reference to GB/T2295-1980 coal tar pitch ash determination methods；
Test result：As shown in table 1.
Table 1.
| A1 | A2 | A3 | D1 | |
| Softening point, DEG C | 300 | 280 | 290 | 295 |
| Residual carbon content, % | 82 | 76 | 81 | 80 |
| Content of ashes, % | 0.06 | 0.07 | 0.06 | 0.06 |
| Softening point deviation, DEG C | ±5 | ±6 | ±8 | ±20 |
By result in table 1 it is found that (being directly thrown into material asphalt particle vertical with comparative example 1 according to prior art
In reaction kettle) prepared by high softening point bitumen D1 compare, it is according to the present utility model
High softening point bitumen A1-A3 prepared by embodiment 1-3 not only can by softening point, residual carbon content and content of ashes
Reach, be even more than the effect of optimization of D1, moreover, the softening point deviation smaller of high softening point bitumen A1-A3, this represents basis
High softening point bitumen prepared by the utility model method has better uniformity, is more advantageous to improving high softening point bitumen
Stability, in favor of the subsequent applications of the high softening point bitumen.
The preferred embodiment of the utility model described in detail above, still, the utility model is not limited to this.At this
In the range of the technology design of utility model, a variety of simple variants can be carried out to the technical solution of the utility model, including each
Technical characteristic is combined with any other suitable method, these simple variants and combination should equally be considered as the utility model
Disclosure of that belongs to the scope of protection of the utility model.
