Description
Technical Field
The invention relates to modified catalytic slurry oil and a method for preparing road asphalt by using the same.
Background
The catalytic cracking of heavy oil is one of the important secondary processing means in petroleum processing, and in order to reduce the carbon deposition of the catalyst and prolong the service life of the catalyst, a certain proportion of oil slurry is thrown out from a catalytic cracking unit, and is mostly used for producing fuel oil or mixed with residual oil to a coking unit, but the combustion performance of the FCC oil slurry is affected due to the existence of catalyst particles in the FCC oil slurry, and in addition, the catalytic cracking of heavy oil is not the best utilization way in terms of the principle of maximizing the benefit.
In order to increase the value of the FCC slurry oil, some companies have begun to use the slurry oil for the production of bitumen. The more used technology is to carry out decompression and topping on the oil slurry, return the light components to a secondary processing device, and blend the heavy oil slurry and the deoiled asphalt or the decompression residue oil to produce the asphalt product. However, because the oil slurry contains more double bond components, catalyst particles and the like, the catalytic oil slurry has the characteristics of poor high-temperature performance, poor temperature sensitivity and poor aging resistance, which are shown in that the softening point, the dynamic viscosity at 60 ℃, the penetration index and the properties after an aging test of the blended asphalt are poor, and the change is more obvious along with the increase of the addition amount of the asphalt. As a result, either lower grades of road asphalt can be produced or the quality and performance of the original grade asphalt is reduced, and the addition of too much asphalt can affect a series of problems in the process of sale and use.
CN1302841A discloses a method for treating catalytic slurry oil, wherein the catalytic slurry oil needs to be subjected to reduced pressure distillation, and the obtained heavy component is mixed with solvent deoiled asphalt, slag-reduced after oxidation or mixed with reduced pressure residual oil and then oxidized to produce qualified road asphalt.
CN102559250A discloses a method for producing asphalt blend oil by catalyzing atmospheric distillation of slurry oil. Adding a certain amount of steam partial pressure regulator and peroxide into oil slurry, heating the mixture to 360-420 ℃, and introducing the mixture into a fractionating tower for fractionating to obtain heavy fraction at the bottom of the tower, which is higher than 360 ℃, as asphalt blending oil. The method can obtain the asphalt blending component by adopting an atmospheric distillation method, but does not mention the improvement of the temperature sensitivity and the ageing resistance of the produced road asphalt, and the increase of the viscosity of the heavy oil slurry, namely the blending oil at 100 ℃ after oxidation is mainly caused by distilling out light fractions.
CN 105273421A discloses a catalytic slurry oil utilization method, which comprises the steps of adopting bottom reducing residue oil obtained by vacuum distillation of catalytic slurry oil as a raw material, adding a cross-linking agent into the bottom reducing residue oil to carry out cross-linking condensation reaction to prepare condensed slurry oil, and blending the condensed slurry oil and matrix asphalt to obtain road asphalt, wherein the cross-linking agent is one or more of a peroxide cross-linking agent, a sulfur and sulfide cross-linking agent and a metal oxide. The method utilizes the improved catalytic slurry oil as a modifier for the base asphalt, but specific improvement effects cannot be known from the patented method.
