Description
Technical field
The present invention relates to coal chemical technology, the production method of specially high bitumen content fuel oil.
Background technology
It is coal tar pitch to have about 55% after coal tar processing, in recent years, due to by aluminium metallurgy and electric furnace steel making row
The restriction of industry carbon material consumption, pitch demand are in saturation state.Preparation of fuels oil, carbon black oil
It is effective way that coal tar pitch is utilized, but is affected by requirements such as the quality index such as viscosity and proportionings, consumption
It is restricted.Typically fuel oil is configured to by pitch and carbolineum, about 35% carbolineum need to be allocated into, remaining 65%
For pitch, and carbolineum price is far above the price of fuel oil.Therefore carbolineum consumption should be reduced as far as possible,
Improve pitch allocation ratio.
Qu Xiuzhen etc. (with maltha and carbolineum preparation of fuels oil. fuel and chemical industry, 2000, (3)：
142) there is unsalable situation for reply pitch, with maltha and carbolineum preparation of fuels oil, substitute open hearth and
The heavy oil of steel rolling.The method production for converting the less carbolineum of viscosity is returned from 40 DEG C of maltha of softening point
Fuel oil.The dress tar 20t per kettle, carbolineum amount of allocating when joining fuel oil are 1.8t.Softening when pitch
During o'clock more than 40 DEG C, it is the quality for ensureing fuel oil, asphalt softening point often increases by 1 DEG C, the converting of carbolineum
People's amount just need to accordingly increase 1OOkg.The method will need to use more anthracene when asphalt softening point is high
Oil.Chinese patent " a kind of blending technology of coal-tar fuel (CN200610134968.9) " takes coal tar
Raw material is filtered and goes removing glue through 10 mesh, 20 mesh, 40 mesh, 60 mesh, the multistage selected formula filter of 80 mesh
Matter, asphalitine and ash impurities composition are input in gun barrel, and being heated to more than 70 DEG C carries out oil
Water is separated, and is then sent into the feedstock oil after dehydration after mixing with a certain proportion of combustion adjuvant in storage tank,
Again through 80 mesh filters filtration after product.The technique coal tar is directly allocated after filtering, focusing
In oil, the resource such as benzene class, phenols and naphthalenes does not make full use of, and easily causes pollution.Chinese patent
" from coal tar production chemicals and the method (CN200410012455.1) of fuel oil " is by coal tar
Be fractionated into light, weigh two fractions.The hydrogenated refined or modification production light-end products of light fraction.Tar is dripped
Blue or green processing is combined with coke oven or is combined with delayed coking, the more chemical products phenol of production, naphthalene and
Gasoline, diesel oil or light Fuel etc..The invention mainly reclaims cut therein or combustion using coking process
Material oil, complex process.
Content of the invention
The present invention is intended to provide a kind of production method of high bitumen content fuel oil.
To achieve these goals, technical scheme is as follows：
A kind of production method of high bitumen content fuel oil, which comprises the steps：
After carbolineum and pitch are mixed in the molten state, thinner and stabilizer is added, 90～180
After being sufficiently mixed at DEG C, sample analysis, collect after product is qualified.By measuring tank or metering
Table pump adds thinner and stabilizer from trench bottom is prepared, and it is 200～500mm to add height, from 4
The 20 side aperture of Ф of individual different directions flows out (bottom end closure), reduces flow velocity, prevents electrostatic.

Preferably, the weight ratio of the carbolineum and pitch is (5～25)：(70～75).Pitch
Ratio is suitable, too low high cost, too high easy plug nozzle.
Preferably, the addition of the thinner is the 5～20% of carbolineum and pitch gross weight.
Thinner adds very few viscosity reducing effect poor, and adding can excessively affect the flash-point of fuel oil (to require >=120
℃)
Preferably, the thinner be tar, 150～250 DEG C of cut by-product in benzene processing
Thing.Cause bumping for preventing water from entering in high temperature groove, should also control the water content of thinner must not
More than 1.0%
Preferably, the reduction stick be dephenolize oil, heavy benzol, in methyl naphthalene Residual oil at least
A kind of.
Preferably, the addition of the stabilizer is the 0.03% of carbolineum and pitch gross weight.
Preferably, the stabilizer is naphthalenes sulfonated polycondensation macromolecular compound or anthracene class sulfonation
Polycondensation macromolecular compound.Such stabilizer can prevent particulate matter from precipitating.
Preferably, in order to ensure allotment safety, prevent low boiling material from entering punching in high temperature groove
Material or volatilization loss, and prevent low-flash material from meeting the danger that high temperature occurs fire, it is necessary to control is adjusted
The temperature of timing.It is different according to flash-point,
When the thinner is dephenolize oil, well-mixed temperature is 100～120 DEG C；
When the thinner is heavy benzol, well-mixed temperature is 90～100 DEG C；
When the thinner is methyl naphthalene Residual oil, well-mixed temperature is 120～180 DEG C.
Preferably, the index of the fuel oil is：Moisture≤0.5%, sulfur content≤1.0%,
Calorific value >=37.7MJ/Kg, ash content≤0.3%, flash-point >=120 DEG C, grace formula viscosity≤15 at 100 DEG C,
Density≤1.23g/cm at 20 DEG C3.
The advantage of the present invention is：
The present invention is that price is relatively low using the accessory substance in coking process, replaces part price relatively
High carbolineum, is configured to proper fuel oil with the pitch compared with high mixture ratio, had both improve calorific value and can
Combustion property, reduces the cost of preparation of fuels oil again.Compared with the fuel oil being formulated conventionally, its pitch
Consumption increased 10%, and the consumption of carbolineum reduces 30%.
