The difference between reactive black and fluidized black

1. reactive black and fluidized black sources and production process

Reactive black is mainly produced by the coking process of coke, mainly formed in the fixed bed coking process. Coke burns at high temperature, and its internal carbides decompose at high temperature to generate black coke, which is the main source of active black. The formation process of reactive black depends on the quality of coke and the regulation of coking process, so its quality characteristics are closely related to the source of coke.

The production method of fluidized black is different from that of active black, and it is mainly produced by fluidized bed technology. Fluidized bed technology forms gasification reaction at high temperature by mixing pulverized coal and combustion improder. Through the structural design of the fluidized bed, the pulverized coal is evenly distributed in the bed, so as to realize more efficient combustion and carbonization reaction. The production process of fluidized black is more continuous and automated, the production efficiency is higher, and the energy consumption is relatively low.

2. REACTIVE BLACK AND FLOW BLACK QUALITY CHARACTERISTICS

There are significant differences in physical and chemical properties between reactive black and fluidized black. Reactive black is mainly composed of carbonaceous material, has a large specific surface area and the aggregation of black particles. This characteristic makes it have an important adsorption effect in coal chemical industry, which can effectively remove sulfur, nitrogen and other impurities, and is an efficient and environmentally friendly adsorption material.

In contrast, the particle structure of fluidized black is more uniform, and its apparent density and particle distribution are more ideal, which is suitable for different application fields. The composition of fluidized black not only contains carbonaceous materials, but also contains a small amount of sulfur and impurities, so it needs to be properly screened and treated when used.

, Reactive black and fluidized black applications

Reactive black is mainly used for desulfurization and ash removal system in coal chemical industry. Because of its efficient adsorption characteristics, it has become a standard product in coal chemical industry at home and abroad. In industry, reactive black is widely used in coking, pet-coating, coal tar processing and other fields, playing an irreplaceable role.

The application of fluidized black is more extensive, especially in pet-coating and coal tar processing. With uniform particles and high apparent density, fluidized black is a multifunctional coal chemical material, which is suitable for the application of various fillers and catalysts.

4. reactive black and fluidized black safety and environmental protection characteristics

Reactive black requires high temperature treatment in the production process, which puts forward higher requirements for the health of operators and the use of equipment. Reactive black has a certain adsorption in use, which may cause certain pollution to the environment. Therefore, it is necessary to pay attention to environmental protection measures in the production process, and take appropriate decolorization technology and wastewater treatment measures.

The production process of fluidized black is relatively mild, the impact on equipment and operators is small, and the production energy consumption is relatively low. It is a more environmentally friendly production method. The fluidized black has high stability and less pollution to the environment in the process of use, which is a kind of coal chemical material worthy of promotion.

5. Reactive Black and Flow Black Development Trend

Reactive black and fluidized black are two important coal chemical materials, and the future development trend will be in the direction of high efficiency, environmental protection and multi-function. Reactive black has irreplaceable advantages in desulfurization and ash removal, while fluidized black has significant advantages in particle uniformity and application range. In the future, with the progress of science and technology, the production process of reactive black and fluidized black will be more optimized, and its application in coal chemical industry will be more extensive and in-depth.

6. conclusion

Reactive black and fluidized black as two important coal chemical materials, although there are significant differences in the source, production process, quality characteristics and other aspects, but in the environmental protection, economic and social benefits have important value. Reactive black has unique advantages in desulfurization and ash removal, while fluidized black has significant advantages in particle uniformity and versatility. In the future, with the development of science and technology, active black and fluidized black will play a more important role in coal chemical industry and make greater contributions to industrial development and environmental protection.

Through the detailed analysis of this article, we hope to help readers better understand the difference between active black and fluidized black, so as to make a more informed choice in practical applications.
