Method for producing mesophase pitch

FIELD: oil and gas industry. SUBSTANCE: invention relates to production of raw material for production of isotropic dense graphitized structural materials and can be used in oil refining industry. To obtain mesophase pitch, the raw material is heated and subsequently carbonized with raising temperature at a rate of not more than 20 °C per hour to temperature of carbonization and formation of mesophase. When this temperature is reached, conditions which stimulate growth of the number and size of mesophase particles are maintained. By raising the temperature, the formed mesophase matrix is fixed. As raw materials there are used asphaltenes obtained as a result of rectification heated from 300 to 320 °C from commercial heavy high-viscosity oil in vacuum column with top temperature of not less than 125 °C, bottom temperature of not less than 350 °C and an absolute top pressure of 8 kPa with subsequent deasphalting of the tar removed from the bottom of the column. Material is heated from carbonation beginning temperature of 530–550 °C to the temperature of completion of formation of mesophase 630–650 °C and fixation temperature of mesophases 780–800 °C at rate of 20 °C per hour. Pyrolysis of the feedstock is carried out in an inert atmosphere at pressure of 5 to 8 MPa to obtain mesocarbon microspheres, which are directed for further processing, and a loose coke residue, which is sent for demetallization.

ABSTRACT OF THE DISCLOSURE Depending on requirements and intended use crude pitches are mixed from coal-tar-pitch fractions obtained by extraction with an above-critical gas and an entraining agent from the above-critical solution by gradually changing the pressure and the temperature. Ash-free as well as QI-free and TI-free fractions are obtained. Primarily low-boiling aliphatic and olefinic hydrocarbons are used as extracting agents and aromatic hydrocarbons as entraining agents. The crude pitches are used, for example, for producing carbon black and for producing carbon mouldings.

Production of methylnaphthalenes and tar bases including indole

ABSTRACT Methylnaphthalenes, indole and other tar bases are recovered from a base-extracted coal tar distillation fraction. In one form, an aqueous salt solution of pH 0.5-3 extracts other tar bases from the starting material, and thereafter both products are recovered from the raffinate by several alternate methods including ethylene glycol extraction and extractive distillation. In other forms, the starting material is extracted with ethylene glycol and the extract is distilled to recover several products including indole. The raffinate of ethylene glycol extraction contains methylnaphthalenes and other hydrocarbons and can be purified to solvent-grade material.

Device and method for preparing chemicals by fractions in coal tar

OF THE DISCLOSURE A device and method for preparing chemicals by reaction, separation and reaction of fractions in coal tar are disclosed. Single components of polycyclic aromatic hydrocarbons (bicyclic, tricyclic and tetracyclic) in the coal tar are used as a core, and coal tar distillate oil, with rich polycyclic aromatic hydrocarbons, of the coal tar after fraction cutting is subjected to dealkylation to be normalized, thereby effectively enriching the single components of the polycyclic aromatic hydrocarbons in the coal tar, and remarkably reducing separation difficulty and energy consumption in a separation section. A large difference of freezing points of the polycyclic aromatic hydrocarbons (bicyclic, tricyclic and tetracyclic) is used for separating the polycyclic aromatic hydrocarbons by means of constant temperature condensation and centrifugal filtration. A separation process is carried out at a normal pressure and a low temperature, thereby effectively reducing the energy consumption of the separation section. Aiming at improving high value-added utilization of the polycyclic aromatic hydrocarbons in the coal tar, a high-purity fraction obtained by means of a polycyclic aromatic hydrocarbon separator can be further processed into a partially-hydrogenated polycyclic aromatic hydrocarbon chemical with a higher added value by means of a hydrogenation reaction. 1/3 Aromatic Hydrodealky - - hydrocarbon fraction atio separation/purification |DistillationI and Selective Single component of Chemical 4 purification hydrogenation polycyclic aromatic unit hydrocarbon FIG. 1 Secondary product Gas4 7 2L 15 distillate C 4 7t2 PrimarGy product FIG. 2

Distillation apparatus and additive manufacturing equipment comprising same

The present invention relates to a distillation apparatus for fractionating impurities from a raw material by a fractional distillation method using a boiling point difference to modify the raw material, the distillation apparatus comprising: a reactor having an internal space capable of heat treating the injected raw material and moving the separated impurities; and an impeller installed in a lower part of the reactor and including a blade rotating while supplying hot air into the reactor. Thus, according to an embodiment of the present invention, since the hot air is supplied while the impeller is rotating, the hot air, which is a heat source, can be uniformly transferred to the inside of the distillation apparatus. As a result, the raw material, which is an object to be treated, uniformly contacts the hot air, which is a heat source, thereby improving the separation efficiency of impurities. Therefore, since the content of impurities is low, a high-quality additive can be manufactured.

Patent BE448809A

Pitch production, fractionation and high softening point pitch

A process for thermally polymerizing a liquid hydrocarbon pitch precursor, or fractionating a crude pitch, by direct contact heating with an immiscible molten fluid, preferably molten metal, is disclosed. A crude pitch, which may contain water, contaminants and/or distillables, or a liquid hydrocarbon feed such as FCC slurry oil, is heated by direct contact heat exchange with molten fluid, preferably a molten metal bath, operating at a temperature of 100 to 6000C. The bath is maintained at a temperature and pressure sufficient to induce thermal polymerization of a pitch precursor and/or vaporize a desired amount of contaminants or volatile material from a crude pitch to produce a pitch product having a desired softening point. New pitch compositions having a high softening point are also produced.
