Embodiment 1

[0029] Heat the catalytic oil slurry to 190°C, add powdered condensed aluminum phosphate (aluminum tripolyphosphate, fineness 800 mesh) into the catalytic oil slurry, of which the catalytic oil slurry accounts for 98.7wt% of the total, and the condensed aluminum phosphate accounts for the total The amount of 1.3wt%, at 190 ℃, with ordinary stirring and mixing reaction for 240min, and then the modified catalytic oil slurry was obtained.

[0030] The modified catalytic oil slurry is subjected to vacuum distillation to distill out the light fraction <420°C, and the yield of the light fraction is 30wt%, to obtain the topped modified catalytic oil slurry. Heat the base asphalt to 155°C to melt, add the above-mentioned modified catalytic oil slurry to the base asphalt, wherein the base asphalt is a vacuum residue with a penetration of 55 1 / 10mm at 25°C and a softening point of 49.2°C. Accounting for 85wt% of the total, the above-mentioned topping modified catalytic oil slurry accoun...

Embodiment 2

[0032] Catalytic oil slurry accounted for 95.0wt% of the total, condensed aluminum phosphate (aluminum dihydrogen phosphate, fineness 800 mesh) accounted for 5.0wt% of the total, and other conditions were the same as in Example 1 to obtain modified catalytic oil slurry.

[0033] The conditions for the vacuum distillation of the modified catalytic oil slurry and the process conditions for preparing road asphalt by mixing with base asphalt are the same as in Example 1. The properties of road asphalt are shown in Table 2.

Embodiment 3

[0035] The catalytic oil slurry accounted for 99.8wt% of the total amount, and the condensed aluminum phosphate accounted for 0.2wt% of the total amount. Other conditions were the same as in Example 1 to obtain a modified catalytic oil slurry.

[0036] The conditions for the vacuum distillation of the modified catalytic oil slurry and the process conditions for preparing road asphalt by mixing with base asphalt are the same as in Example 1. The properties of road asphalt are shown in Table 2.

Abstract

The invention discloses a modified catalytic oil slurry and a method for preparing a road asphalt by using the modified catalytic oil slurry, wherein the modified catalytic oil slurry comprises 95.0-99.9% of catalytic oil slurry and 0.1-5.0% of a modifier, and the modifier is one or a plurality of materials selected from condensed aluminum phosphate and a silicon phosphate curing agent. Accordingto the present invention, the temperature-sensing property and the anti-aging property of the road asphalt obtained by blending the modified catalytic oil slurry and matrix asphalt are significantly improved.

Description

technical field [0001] The invention relates to a modified catalytic oil slurry and a method for preparing road asphalt. Background technique [0002] Heavy oil catalytic cracking is one of the important secondary processing methods in petroleum processing. In order to reduce catalyst carbon deposition and prolong its life, a certain proportion of oil slurry is usually thrown out of the catalytic cracking unit, most of which are used to produce fuel oil or mixed with residual oil for further processing. Coking unit, however, due to the presence of catalyst particles in FCC oil slurry, its combustion performance will be affected. In addition, from the principle of benefit maximization, it is not the best way to use it. [0003] In order to improve the utilization value of FCC oil slurry, some enterprises began to use oil slurry for asphalt production. The most used technology is to decompress the oil slurry, return the light component to the secondary processing device, and ...
