Description
Technical field
The present invention relates to a kind of method that civilian clean coke is produced using coal directly-liquefied residue
Background technology
Based on the special primary energy natural endowment structure of China's " rich coal, oil-poor, few gas ", coal is at present or even future very long one
It is still the indispensable significant energy source of China's production and living in the section time.For coal as primary energy, its is direct or indirect
Burning is essential process.China is coal-fired every year, and particularly civilian dissipate combusts coal, have coal consumption it is big, using wide, dirty
The characteristics of thing is in line is contaminated, serious harm is caused to ecological environment, particularly atmospheric environment.Therefore, prepare environment-friendly
Domestic fuel burns the important channel that raw coal is improvement atmospheric environment to substitute to dissipate.
The carbonated starting material of the mesh of granularity≤80 is proportionally added into and mixed into as-fired coal by patent of invention CN103880592A
Load destructive distillation stove heat afterwards, be then down to normal temperature through quenching, then after screening, solid cleaning fuel is prepared.Patent
Red mud compound additive is added in mixed coal by CN105733726, air heating is completely cut off in gas retort, under assigned temperature
Destructive distillation special time, normal temperature is down to through quenching process after red heat furnace charge is come out of the stove, is obtained after screening containing red mud compound additive
Domestic coke.Domestic coke obtained by foregoing invention produces gained, it is firing by adding auxiliary agent in mixed coal after destructive distillation
Pollutant discharge amount substantially reduces during burning, can be used as and dissipate the purifying alternative fuel of coal improvement.However, due in civilian cleaning
It is difficult to break away from the dependence to coking coal resource in coke production, causes civilian clean coke production cost to remain high, pole
The earth limits domestic coke and promotes and apply.
Direct coal liquefaction technology can provide abundant chemicals, but can produce simultaneously account for liquefaction raw coal total amount 20%~
30% liquefied residue.Liquefied residue is the mixture of a kind of high-carbon, high ash and high-sulfur, and is listed in《National Hazard waste name
Record》(2016 editions), how green, efficiently handle this dangerous waste thing of liquefied residue the problem of being worth thinking deeply about.Liquefied residue
By organic components such as Residual oil and asphaltenes, it is difficult to be dissolved in inorganic mineral and addition in the unconverted coal and coal of organic solvent
The three parts such as catalyst form.Because asphaltene is the solvable macromolecule organic mixture of a kind of toluene or benzene, its have compared with
