Abstract

The invention discloses a catalyzing and cracking slurry oil settling agent. The catalyzing and cracking slurry oil settling agent is prepared from raw materials including, by weight, 10.0-12.0% of polyoxyethylene and allyl polyethylene oxide block polymers, 7.0-8.0% of PPG (poly propylene glycol) 8000, 5.0-7.0% of dimethyl diallyl ammonium chloride homopolymers, 4.0-6.0% of polyoxyethylene sorbitan laurate and the balance of aromatic hydrocarbon oil. The invention further discloses preparation method and application of the catalyzing and cracking slurry oil settling agent. Attraction between the catalyzing and cracking slurry oil and solid catalyst powder can be lowered by the aid of the formulated settling agent, settling velocity and remove rate of the catalyst powder are increased, ash content is effectively reduced, and quality is further guaranteed for the catalyzing and cracking slurry oil settling agent.

Description

technical field [0001] The invention relates to the technical field of sedimentation agents, in particular to a catalytic cracking oil slurry sedimentation agent and its preparation method and application. Background technique [0002] Catalytic cracking (FCC) oil slurry is the heavy product at the bottom of the main fractionation tower of the FCC unit. Polycyclic aromatic hydrocarbons. FCC oil slurry has good economic value, it can be used as raw material for carbon black oil, needle coke and rubber extension oil, and can also be used as raw material for hydrocracking and FCC, but because FCC oil slurry contains 2000-9000ppm of catalyst solid powder As a result, its economic scale and value-added utilization are greatly limited. To make full and effective use of FCC oil slurry, the catalyst solid powder in the oil slurry must be removed. [0003] Existing technologies for removing catalyst solid powder include: natural sedimentation method, additive sedimentation method,...
