Abstract

The invention provides a residual oil desulfurization method, a petroleum coke preparation method and production equipment, and relates to the technical field of petroleum coking. The residual oil desulfurization method comprises the following steps: S1) providing residual oil as a reaction raw material, and combining the residual oil with the pre- Mixing the treatment agent to pretreat the residual oil; wherein, the pretreatment agent includes metal alkali and / or metal carbonate; S2) placing the pretreatment mixture obtained in step S1) in an electrostatic field for electrostatic adsorption desulfurization treatment, and then completing Desulfurization of residual oil to obtain residual oil with low sulfur content. The residual oil desulfurization method can alleviate the technical problems of high process difficulty, high cost and poor desulfurization effect in desulfurization of petroleum coke in the prior art, and desulfurization from raw materials can reduce the difficulty of desulfurization and improve the desulfurization effect.

Description

technical field

[0001] The invention relates to the technical field of petroleum coking, in particular to a residual oil desulfurization method, a petroleum coke preparation method and production equipment. Background technique

[0002] Petroleum coke is a kind of coke made from residual oil through delayed coking. At present, most of my country's petroleum coke products are high-sulfur petroleum coke (sulfur content is higher than 3%). The use of high-sulfur petroleum coke will not only cause corrosion of equipment, increase the production cost of enterprises, but also cause serious pollution to the environment. With the country's emphasis on environmental protection in recent years and the gradual upgrading of environmental protection levels, the demand for high-quality low-sulfur petroleum coke will increase in the future, so it is imperative to reduce the sulfur content in petroleum coke.

[0003] At present, in order to obtain low-sulfur petroleum coke, high-sulfur pe...
