Abstract
A diesel oil using coal resources as its raw material is prepared from medium-temp coal tar oil, low-temp coal tar oil, light oil and washing oil through removing dregs, desalting, dewatering, catalytic cracking and rectifying.
Description
The present invention relates to a kind of is the necessity of raw material production Coalificat diesel oil with coal-tar middle oil, coalite tar, light oil, washing oil:
At present, the main source of China's diesel oil is with refining of petroleum, and China is the country of the few oil of a rich coal.The national statistics data showed in 1998, and the retained reserve of domestic coal is 10070.7 hundred million tons, and workable reserves is 7,650 hundred million tons; The oil prognostic resources is 94,000,000,000 tons, and workable reserves is 52.6 hundred million tons; In the explored reserves in the world, China's Oil accounts for 2.7%, and coal accounts for about 15%.Therefore, the exploitation coal resources are converted into the alternative oil of diesel oil has crucial meaning as automotive fuel.
At present, the crude oil in China import volume is increased sharply.According to the statistics from customs, only in January, 2003, the crude oil in China import volume up to 8,360,000 tons, increases by 77.7% on a year-on-year basis.It is predicted that China's Imported oil will reach 100,000,000 tons in 2005.Sophistication, continue energy-conservation, quicken the renewable energy source development and use and rely under the condition that market forces optimize allocation of resources, the still short energy 8% in 2010, to the year two thousand forty with shortage about 24%, wherein oil shortage may reach several hundred million tons.
The objective of the invention is to: with coal-tar middle oil, coalite tar, light oil, washing oil is raw material, produces the Coalificat diesel oil that meets national automobile-used standard.
The invention has the beneficial effects as follows: with coal resources is the raw material production Coalificat diesel oil, alleviates the undue dependence of vehicle fuel to petroleum products, reduces the import volume of oil.
Implementing method of the present invention is as follows:
Coalificat diesel oil
1. coal-tar middle oil, coalite tar 100%
Na
2CO
3 12％
NaOH 10％
Catalyzer
Wherein: described coal-tar middle oil, coalite tar are with Na
2CO
3Remove ammonium salt, remove phenates, behind the normal temperature dewatering,, get Coalificat diesel oil after the rectifying through catalytic pyrolysis with NaOH.
2. light oil, washing oil 100%
CH
3CH
2OH 10％
Benzoyl peroxide 2%
Wherein: described light oil, washing oil are the coal-tar heavy oil purified product, with CH
3CH
2OH removes benzene, coumarone, indenes, naphthalene, methylnaphthalene, dimethylnaphthalene, acenaphthene, biphenyl, fluorenes, dibenzofuran, quinoline, indoles, the phenol in light oil, the washing oil.With the benzoyl peroxide is that oxygenant is made with extra care, and gets Coalificat diesel oil after the rectifying allotment.
2. preparation method
Coalificat diesel oil:
A. (1) takes off slag, coal-tar middle oil, coalite tar is carried out three sections take off slag, makes dregginess be not more than 0.3％，
(2) the static evaporation of heating is adopted in dehydration, makes coal tar moisture reduce to 0.3％——0。5％，
(3) 12%Na is used in desalination
2CO
3Take off ammonium salt in the tar and 10% NaOH and take off phenates.After carry out catalytic pyrolysis, the gas oil after the cracking is added to obtains the finished product Coalificat diesel oil in the rectifying tower after the rectifying.
B. after light oil, washing oil being carried out oxidation distillation with benzoyl peroxide, use CH
3CH
2OH removes benzene, coumarone, indenes, naphthalene, methylnaphthalene, dimethylnaphthalene, acenaphthene, biphenyl, fluorenes, dibenzofuran, quinoline, indoles, the phenates in light oil, the washing oil.The back adds rectifying tower rectifying after modulation obtains the finished product Coalificat diesel oil.
Claims (2)
1. a Coalificat diesel oil is characterized in that taking off slag, dehydration, desalination, oxidation, cracking, rectifying, modulation with coal-tar middle oil, coalite tar, light oil, washing oil.Its raw material amount ratio is:
Coalificat diesel oil
Coal-tar middle oil, coalite tar 100%
Na
2CO
3 12％
NaOH 10％
Catalyzer
Wherein: described coal-tar middle oil, coalite tar are with Na
2CO
3Remove ammonium salt, remove phenates, behind the normal temperature dewatering,, get Coalificat diesel oil after the rectifying through catalytic pyrolysis with NaOH.
2. light oil, washing oil 100%
CH
3CH
2OH 10％
Benzoyl peroxide 2%
Wherein: described light oil, washing oil are the coal-tar heavy oil purified product, with CH
3CH
2OH removes benzene, coumarone, indenes, naphthalene, methylnaphthalene, dimethylnaphthalene, acenaphthene, biphenyl, fluorenes, dibenzofuran, quinoline, indoles, the phenol in light oil, the washing oil.With the benzoyl peroxide is that oxygenant is made with extra care, and gets Coalificat diesel oil after the rectifying allotment.
