Gas processing

The raw materials of the active carbon used for wasted gas processing are the charcoal from Shanxi, and the carbon is manufactured after the strict technique such as shattering, carbonization, activation and refining. It has the features of large surface area rate, developed pore structure, rational pore distribution, strong absorption capability, even particle distribution and large abrasive resistance. It is used in the purification of the gas for raw materials of chemical industry, chemically synthesized gas, gas for pharmacy industry and carbon dioxide for beverages, as well as hydrogen, nitrogen, chlorine, hydrogen chloride, acetylane, ethane, cracking gas and inert gases, as well as the purification of the gas emitted from the atomic facilities. It is also used in eliminating the pollutants in the air as well as the isolation and purification of the mixed gases.


The processing of the polluted water

The active carbon used for processing the polluted water uses the fine charcoal as the raw material, and it is manufactured with the technique of shattering, carbonization, activation and refining. It can purified the living sewage and sewage for chemical industry effectively.


Desulfuration and denitration

The desulfuration and denitration are the cylinder-shape particle and it is dark black; it uses the fine carbon as the raw material and it is manufacturing by the procedures of fine selection, matching, shattering, formulating, drying, carbonization, activation and deep processing with the adhesive and catalyst of a certain proportion added. It has the features of high activation, large poreness, large capacity of sulfur, high efficiency of desulfuration, high mechanical strength, good waterproof, small gas resistance, being easy to regeneration and not being easy to shatter under high pressure. This product is mainly used in the elimination of H2S of various kinds of methane, water gas, semi-water gas, coke-oven gas, natural gas, carbon dioxide, urban gas, synthesized ammonia and the gas in the raw materials for chemical industry.


Solvent recycling

The active carbon used for the solvent recycling and processing uses the fine natural charcoal as the raw material and it is manufactured by the method of physical activation; it is the black particles and has no toxicity and odor. It has developed pores and rational distribution of three kinds of holes, as well as strong absorption capability. Under the wide range of temperature, it can strongly absorb the vapor of most organic solvents, and it is widely applied in the recycling of the organic solvents such as benzene, ether, xylene, alcohol, acetone, gasoline, trichloromethane and carbon tetrachloride.


Ammonia preparer/air isolating equipment

The PSA active carbon specially used for the ammonia preparer uses the fine charcoal as the raw material, and it is manufactured after the working sequences of shattering, grinding, mixing, formulation, carbonization and activation. It has the features of high mechanical strength, regulated shape, even particularity, large surface area rate and few surface dust. The amount of large pores, mediate pores and micro pore is proper; its absorption speed is fast and the bed resistance is very low, and it is suitable for the direct deoxidization of nitrogen, argon, chlorine, carbon monoxide, carbon dioxide and inert gases. It is widely applied in the nitrogen purification equipment and air-isolating nitrogen manufacturing equipment and it is specially used in the post purification and oil absorption for the nitrogen preparation by the method of absorption under high pressure.


The kinds of column-shape active carbon

It mainly includes the charcoal-based column-shape active carbon and the wood-based column-based active carbon (the wood-based active carbon includes coconut shell)


The column-shape active carbon

The wood-based column-shape active carbon uses the fine wood crust and coconut shell as the raw materials and it is manufactured by the procedures of shattering, mixing, pressing, formulating, drying, carbonization and activation. It has the lower ash content than that of the traditional charcoal-based column-.shape carbon; it has fewer impurities and the CTC has the absolute advantages.

It is mainly used in: 1 the gaseous phase absorption, 2. The recycling of the organic solvents (such as benzene-containing gases, methylbenzene and xylene, and the recycling of acetone in the industry of cellulose acetate fiber, and the recycling of carbon disulfide in the production of short adhesive fibers), 3 the elimination of the impurities and harmful gases. This technology ranks the first in China.

The absorption rate of the common 4mm active carbon to CTC is only 60% and it doesn’t exceed 70%; while the absorption rate of the produced 4mm wood-based column-shape active carbon to CTC is 100% and it has made up for the shortcoming of the domestic products on the low absorption rate to CTC. The product has reached the first-rank level in the world and it can totally replace the imported products.

The charcoal-based column-shape active carbon uses the anthracite as the raw material, and it is fine processed with advanced technique. Its outlook is black column-shape particle, and it has the features of rational pore structure, good absorptive performance, high mechanical strength, being easy to regenerate and low cost. It is used in the aspects of purification of toxic gases, water gas processing, purification of the water for production and living and solvent recycling, etc.


Feature

The advancement of the column-shape active carbon

Because it uses the fine wood crust and coconut shell as the raw material, its ash content is lower than that of the traditional charcoal-based column active carbon, it contains fewer impurities and its gaseous phase absorption values and CTC are absolutely advantageous.

The charcoal-based column-shape active carbon has the advantages of developed pore structure, large surface area rate, strong absorption capability, high mechanical strength, low bed resistance, good chemical stability, being easy to regenerate and being enduring.

The products have rationally distributed pores and the maximum absorption and desorption can be realized, therefore the service life of the product can be enhanced largely (the average service life is 2-3 years). The service life is 1-4 times of that of the common charcoal-based carbon.


The application of the column-shape active carbon:

1.The gaseous phase absorption.

2.The recycling of the organic solvent (the benzene-containing gas, methylbenzene, the acetone recycling in the industrial of the cellulose acetate fiber)

3.Eliminating the impurities and harmful gases, and the wasted gas recycling

4.The recycling of the excessive gasoline in the oil refinery plant, gas station and oil tank.

5.All the catalysts for the active carbon are tetrachloroethane and trichloro ethylene.
