Abstract
The invention discloses a method for avoiding the coking while desulfurization of petroleum coke. The method comprises the steps of burning solid fuel particles, quartz sand and lime stone in a high-speed fluidized bed; regulating the distribution of a heating surface, and controlling the temperature in a furnace to be 850-900 DEG C so as to play sulfur fixation and coking prevention roles. According to the method, the desulfurization rate of the petroleum coke in the fluidized bed can be improved, coking can be reduced, and further the production efficiency can be improved.
Description
Technical field
The present invention relates to industry manufacture field, the method for coking is avoided in the desulfurization that relates in particular to a kind of refinery coke simultaneously.
Background technology
Refinery coke is one of Main By product of petroleum refining industry, and it is to prepare the particularly main raw material of pre-baked anode for aluminum (be also called carbon anode, be called for short anode) of carbon material.According to the difference of sulphur content, refinery coke is divided into Behavior of High-sulfur Petroleum Coke (S content is not less than 3%) and low-sulfur burnt (S content is not higher than 2%).The content of sulfur in petroleum coke has determined the end-use of refinery coke, and Behavior of High-sulfur Petroleum Coke is mainly used to do fuel.As raw material refinery coke, need to improve its physicochemical property and electrical property through calcining, meet the requirement that carbon anode is produced.The behavior of the quality antianode of refinery coke in electrolyzer and the business performance of anode production have important
Refinery coke is a kind of low ash content, and the fuel that sulphur content is high, in order to form enough recycle stocks and the requirement of desulfurization in fluidized-bed, need to add a large amount of Wingdales as bed material and sweetening agent in circulating fluidized bed.The limestone particle of porous can absorb the SO in flue gas
2, form CaSO
4macromole shell, and kernel is still non-switched limestone particle.Now, the CaSO of shell
4also can continue to increase, between particle, be in contact with one another and can rapidly intergranular gap be filled up, particle is bonded together and stop CaO and the SO of internal layer
2react.Along with particle expands constantly, final particle bond together, causes the generation of coking.
For firing the circulating fluidized bed of refinery coke, with quartzy sandstone, replace traditionally containing magnesium absorption agent, can effectively prevent adhesion between particle, also have splendid economy simultaneously.
Summary of the invention
For this reason, a kind of method that object provided by the invention is to provide desulfurization of refinery coke to avoid coking simultaneously, improves the desulfurization degree Jiao of fluidized-bed PetroChina Company Limited., reduces coking simultaneously and occurs, and then enhance productivity.
For achieving the above object, the method for coking is avoided in the desulfurization that the invention provides a kind of refinery coke simultaneously, and the method adopts solid fuel particle, quartzy sandstone and Wingdale, in high-velocity fluidized bed internal combustion.Adjust heating surface simultaneously and arrange, control temperature in stove and, at 850～900 ℃, can play the effect of the anti-coking of solid sulphur.
Further, wherein, described solid fuel particle is coal particle, base low heat value be not less than 6000 kilocalories/kilogram, granularity is 4～10mm.
Further, wherein, described limestone particle degree should be interval at 0.5～1.0mm.
Further, wherein, the granularity of described quartzy sandstone must be lower than the granularity of Wingdale.
