うなビチューメンを製造できれば有利なことになる。Bitumen is used in road construction, roofing, pipeline coatings, and is widely used as a binder for briquettes. Bitumen is often mixed with aggregates and/or fillers that provide strength to the resulting mixture. For example, in road construction, bitumen is mixed with sand and stones and this mixture is used as road asphalt I-. Needless to say, road asphalt I.
must have sufficient abrasion resistance and micro-abrasion (iB) resistance. It would therefore be advantageous to be able to produce bitumen that exhibits greater microwear resistance when mixed with fillers and/or aggregates.

ことからなるビチューメン製造方法を提供する。Therefore, the present invention provides for subjecting a residue fraction of a pyrolyzed hydrocarbon feedstock to vacuum distillation at a maximum distillation temperature corresponding to the vacuum boiling point of hydrocarbons with an atmospheric boiling point of 455 to 540°C, and at least a portion of the distillation residue Provided is a method for producing bitumen, which comprises recovering bitumen as bitumen.

The boiling point obtained by converting the boiling point under reduced pressure according to the relational expression M'axu+ellBonnell described in 6 is used. In practice, the boiling point of hydrocarbons is measured under reduced pressure, and since different boiling points are obtained depending on different reduced pressures, those skilled in the art prefer to use the defined normal pressure boiling point in terms of conversion.

合性の問題を生じ得る。The maximum distillation temperature is for hydrocarbons with a normal pressure boiling point of 455℃ (455℃
The temperature must be higher than the boiling point of /baru hydrocarbon) = 4-. Otherwise, the relatively light hydrocarbons will not be sufficiently removed, resulting in the formation of a relatively unstable and rapidly aging bitumen as described in Fue 1, supra. On the other hand, the maximum distillation temperature is 54
Above the 0° C. 7 bar hydrocarbon boiling point, the resulting residue becomes too hard to be used, for example, in road asphalt, and can give rise to incompatibility problems when used in bituminous mixtures.

At temperature levels of 0° C., long chain hydrocarbons become unstable and break into smaller molecules of various sizes and types. The feedstock that is pyrolyzed typically consists of a complex mixture of heavy hydrocarbons remaining as a result of atmospheric or vacuum distillation of crude oil. His-breaking, ie, the operation of reducing viscosity by breaking molecules, is an important applied operation of pyrolysis. This is because this operation significantly reduces the viscosity of the residue obtained as a result of pyrolysis. To perform a Vispray kink, a suitably preheated material is first heated to decomposition temperature in a furnace. This material is then sent to a soaking device downstream of the furnace where the bulk of the cracking process occurs. Advantageously, the soaking device has internal baffles to avoid excessive pack mixing. The products are gases, distillates and residues. This residue has a lower viscosity than the raw material. Such residues, ie residues of visbroken hydrocarbon feedstocks, are preferably used as residue fraction in the process of the invention. Suitable visbreaking operating conditions are a pressure of 2 to 30 bar, a temperature of 400 to 500° C. and a residence time of 5 to 60 minutes.

ューメンとして回収される。The residue fraction is distilled under reduced pressure. In this case, if the conditions regarding the maximum distillation temperature are met, the residue fraction is treated with conventional vacuum distillation. However, it is preferable to use flash distillation. In flash distillation, the residue fraction is heated to a temperature within the lower pressure boiling range of the liquid and introduced into a vacuum flash zone to recover the distillate and residue. This residue is recovered, at least in part, as bitumen.

This is because if the temperature is kept below 400°C, the carbon = 7-hydrogen (Misaki) reaction in the residue, such as a decomposition reaction, is almost avoided. Therefore, the actual distillation temperature is preferably set to a lower value, especially 310 to 370°C.In order to meet the conditions regarding the boiling point of hydrocarbons, the pressure of vacuum distillation is set to 2 to 120 mm/g (0.27 to 1 g, 6,0

ある。The bitumen produced by the method of the invention has good ashing properties and stability. To further improve oxidative stability, it is preferred that the bottom fraction of the distillation is at least partially subjected to blow ink before recovery as the desired bitumen. This blow ink treatment is usually carried out continuously by introducing liquid bitumen into the blow ink column and keeping the liquid level therein approximately constant by removing bitumen near the bottom. Air is blown into the liquid via a distributor at the bottom of the column. A suitable blow ink temperature is 170-320'C1, especially 220-275C.

分解処理の間にも新たなアスファルテンが形成される。It is well known to those skilled in the art to mix different bitumens to obtain bitumen compositions exhibiting desired properties. The invention also relates to bituminous compositions comprising bitumen produced by the method of the invention. However, such bituminous compositions must not contain excessive amounts of asphaltenes. This is because in that case, heterogeneity may occur. The use of pyrolyzed residues as mixture components can lead to excessive asphaltene content. This is because the asphaltene content of pyrolyzed residues is quite high, as described, for example, in the above-mentioned Fue 1 journal. This means that heavy hydrocarbon oils are converted to lower boiling point compounds during pyrolysis, but asphaltenes are in the residue? This is due to the reduction in FA. In addition,
New asphaltenes are also formed during the decomposition process.

てもよく、フラックス油を含んでも含まなくてもよい。By shifting the maximum distillation temperature of the process of the invention below 540° C./bar hydrocarbon boiling point, preferably below 510° C./bar hydrocarbon boiling point, the risk of excessive amounts of asphaltenes is largely avoided. The bitumen composition contains 5 to 60% by weight of bitumen produced by the method of the present invention and 95 to 40% by weight of at least one other bitumen component.
It is appropriate to include. Other bituminous components may be selected at will by those skilled in the art. Suitable other bitumen ingredients include straight run bitumen, propane bitumen, flight stock extracts such as furfural extracts. These components may or may not be applied to the blow ink, and may or may not include flux oil.

As is evident from the comparison of the results for ΔR&B, 'C1456 residues I and TI, the bitumen formed by the method of the present invention has higher penetration retention and therefore improved knee zinc properties and lower resistance during heating. There is no loss and the softening point change is small. Residues II and III
A comparison of the results shows that similar properties can be obtained by sequentially applying a gentler flush and blowing ink.
