Abstract

The invention discloses a utilization method of catalytic slurry oil. The utilization method comprises following steps: by mass, 0.1 to 5.0% of a modifier is added into 95.0 to 99.9% of catalytic slurry oil, and stirring is carried out to obtain a modified catalytic slurry oil; the modified catalytic slurry oil and crude oil are mixed, and are introduced into a solvent deasphalting device for solvent extraction to remove light components and obtain deoiled asphalt, wherein the modifier is one or a mixture of a plurality of components selected from condensed aluminium phosphate and silicon phosphate curing agents. The method is capable of realizing full utilization of catalytic slurry oil, improving the poor temperature sensitivity and aging resistance of catalytic slurry oil, increasing the flashing point of deoiled asphalt, and realizing direct using of the deoiled asphalt as hard road asphalt or as a raw material used in blending road asphalt and waterproof asphalt.

Description

technical field [0001] The invention relates to a utilization method of catalytic oil slurry, in particular to a method for producing 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 commonly used technology is to mix oil slurry with crude oil for vacuum distillation to p...
