Abstract

The invention discloses a treatment technology for producing needle-shaped coke raw material oil by using catalytic slurry oil filtration. The technology comprises the processes of pretreatment, liquid-solid separation treatment, reheating treatment, pressure reduction distillation treatment and the like. According to the treatment technology, catalytic slurry oil which is originally difficult totreat and low in economic value has the capacity of being regenerated into high-quality raw material oil required by production of oil-system needle-shaped coke, catalytic slurry oil low in economic additional value is filtered to obtain the needle-shaped coke raw material oil high in economic value, and the problem is solved that since the ash content of a catalytic slurry oil solid is high, slurry oil filtration devices and pipes are easily damaged; the economic benefit of oil refining enterprises is directly improved, the operation and maintenance cost of the devices is lowered, and the technology has high economic benefits.

Description

technical field [0001] The invention relates to the technical field of catalytic oil slurry filtration and oil slurry refining of heavy oil in petroleum refining, and in particular relates to a treatment process and a system for producing needle coke raw material oil by utilizing catalytic oil slurry filtration. Background technique [0002] Needle coke is a high-quality carbon raw material developed in recent years. Its carbon products made after calcination and graphitization have wide application prospects in industry, medical treatment, aerospace, national defense and atomic energy. The carbon produced has the characteristics of high crystallinity, low ablation amount, and low thermal expansion coefficient; the graphite electrode made of it has the characteristics of good heat resistance, high mechanical strength, good oxidation resistance, etc., and has extremely high economic value. [0003] Needle coke is divided into coal-based needle coke and oil-based needle coke a...
