Embodiment 1

[0028] Add 20% anthracene oil in a mass ratio (that is, the mass ratio of the total raw material, the same below) to a reaction kettle at 160°C, turn on the stirring paddle, control the speed at 10r / min, and add high-temperature asphalt with a mass ratio of 7.5% After stirring for 15 minutes, add the same amount of high-temperature asphalt for 4 times and repeat the above steps;

[0029] Then adding mass ratio of 15% wash oil to continue stirring, the speed is controlled at 5r / min, after stirring for 10min, the mass ratio of 7.5% high-temperature asphalt (softening point 95-100 ° C, the same below) is added to the reactor, the speed Control at 10r / min, after stirring for 15min, add 2 equal amounts of high-temperature asphalt and repeat the above steps;

[0030] Then add phenol oil with a mass ratio of 5%, control the rotation speed at 5 r / min, continue stirring for 2 hours, and transport the homogenized active carbon special binder to the storage tank. The asphalt content of ...

Embodiment 2

[0032] Add anthracene oil with a mass ratio of 30% to the reactor at 160°C, turn on the stirring paddle, and control the rotation speed at 8r / min, add high-temperature asphalt with a mass ratio of 6.88% into the reactor, stir for 15 minutes, and then add 4 Repeat the above steps for the high-temperature asphalt of the next equal amount;

[0033] Then add the washing oil with a mass ratio of 12% and continue to stir, the speed is controlled at 4r / min, after stirring for 10min, the high-temperature asphalt with a mass ratio of 6.88% is added to the reactor, the speed is controlled at 8r / min, after stirring for 15min, Then add 2 equal amounts of high-temperature asphalt and repeat the above steps;

[0034] Then add phenol oil with a mass ratio of 3%, control the rotation speed at 5 r / min, continue stirring for 2 hours, and transport the homogenized active carbon special binder to the storage tank. The asphalt content of binder 2# was detected to be 57wt%.

Embodiment 3

[0036] Add anthracene oil with a mass ratio of 40% into the reactor at 160°C, turn on the stirring paddle, and control the rotation speed at 8r / min, add high-temperature asphalt with a mass ratio of 6.25% into the reactor, stir for 15 minutes, and then add 4 Repeat the above steps for the high-temperature asphalt of the next equal amount;

[0037] Then add the washing oil with a mass ratio of 8% and continue to stir, the speed is controlled at 4r / min, after stirring for 10min, the high-temperature asphalt with a mass ratio of 6.25% is added to the reactor, the speed is controlled at 10r / min, after stirring for 15min, Then add 2 equal amounts of high-temperature asphalt and repeat the above steps;

[0038] Then add phenol oil with a mass ratio of 2%, control the rotation speed at 5 r / min, continue stirring for 2 hours, and transport the homogenized active carbon special binder to the storage tank. The asphalt content of binder 3# was detected to be 51wt%.

Abstract

The invention discloses a binder special for coal-based activated carbon and a preparation method of the binder. The binder comprises the following components in parts by weight: 45-65 parts of high-temperature asphalt; 15-45 parts by weight of anthracene oil; 8-15 parts by weight of carbolic oil; and 2-5 parts by weight of washing oil. The binder is prepared by a preparation process researched and developed by the invention. The binder is simple in preparation process, and the produced activated carbon product is high in strength, smooth in surface, less in floating ash and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of coal-based activated carbon, in particular to a special binder for coal-based activated carbon and a preparation method thereof. Background technique [0002] In the preparation process of coal-based granular activated carbon, the kneading section has a great influence on the strength, appearance and yield of the final product of granular activated carbon. The process is to mix coal powder with a certain proportion of binder and water in the equipment Fully mixed at a certain temperature, so that the added binder, water and coal powder are fully infiltrated, infiltrated and dispersed uniformly, and the coal powder will produce interfacial chemical coagulation in the presence of binder and water to form a loose bulk material, which has the characteristics of extrusion Plasticity of compression deformation, easy to form and improve product strength. [0003] The role of adding binder in the kneading moldin...
