Production raw materials and process analysis of powdered activated carbon

Powdered activated carbon: raw materials for production

For example, the activated carbon is prepared from rice husks, the flammable gas, carbon and tar are prepared from waste plants, and the activated carbon is used to prepare activated carbon. The chemical department of our school has also produced a large amount of activated carbon from local resources, wheat straw and corn stover instead of wood. In the research work, the subject has been judged by the provincial level in 1999. In addition to this, it is also reported that sugar cane bagasse, organic industrial waste, etc. are used as raw materials for the preparation of activated carbon.

Powdered activated carbon: production equipment

The activation furnace is the main key equipment for the production of activated carbon. Although the rotary furnace has simple operation, low labor intensity, uniform material activation and stable product quality, due to the high temperature of the flue gas, some zinc chloride in the gas phase is brought in to increase the consumption. If the grid furnace is used, although the power is low, Occasionally, there is a disadvantage of inequality in carbonization activation, but the operation flexibility is large and the pollution is easy to handle. How to weigh the two, experts are exploring this, I believe that in the near future there will be a small-scale, high degree of mechanization, product quality and stable high-efficiency activation furnace.

Powdered activated carbon: production process

Following the enhancement of people's awareness of environmental protection, the physical activated carbon process will gradually be paid attention to by people. In order to improve the adsorption function of physical activated carbon, various production units have tried many times, for example, changing the high-temperature steam activation process twice. Significantly improve the decolorization of the product.

Powdered activated carbon production method: zinc chloride method and physical method production;

Characteristics of powdered activated carbon: It has developed mesoporous structure, large adsorption capacity and fast filtration.

Powdered activated carbon applicable fields: mainly suitable for various high-pigment solutions such as phenol absorption industry, amino acid industry, refined sugar decolorization, monosodium glutamate industry, glucose industry, starch sugar industry, chemical additives, dye intermediates, food additives, pharmaceutical preparations, etc. Decolorization, purification, deodorization, and impurity removal.
