  • Physical Activation Activated Carbon

Classification Introduction

Physical Activation. The production of Activated Carbon by a two-stage thermal process involving first, the carbonization of raw material followed by gasification in a controlled manner with an oxidising agent such as steam or carbon dioxide at elevated temperature (800 – 1100°C).This process leads to a well-developed porous structure with little or no chemical activation (pure carbon surface) and hence adsorbs rapidly and strongly. The physical activation process retains most of the natural pore structure of the precursor materials, while developing an extensive micropore and mesopore system. The process is “environmentally friendly” yielding a pure carbon product with very few chemical additives making it suitable for the highest purity applications requiring the natural adsorptive character of activated carbon. The product is useful in both liquid and gas phase applications where pure uncontaminated adsorption is necessary.

Product Advantages and Characteristics

  • Pure Carbon Surface Chemistry: This implies that there is little or no chemical leach resulting from tarry or other chemical residue from manufacturing of graphitised materials so that a ‘carbide’ surface is presented for adsorption without the possibility of possible contaminant displacement (?).
  • Well-Developed Microporous Structure: These have only a few, well-developed micropores (impossible to get large pores from micropores by gasification?) suitable for adsorbing small molecules and gas etc.
  • Environmentally Friendly Production: This is essential for a manufacturer not to employ chemicals so that the usual use of steam or CO2 is essential. Of course this reduces the environmental aspects of the method to a minimum.
  • Excellent Thermal Stability: Since these materials are activated at much higher temperatures, this should give an end-use product of high stability with maximum retention of adsorption at higher temperatures.

Relevant Application Scenarios

Water Treatment
Air / Gas Treatment
Food & Beverage
Medical

Water Treatment

 

Description: Physically activated carbon clarifies water through inherent adsorption and without chemical residues.

Drinking Water Treatment

free of chemical residues. Removes contaminating organic substances, taste, and odour.

Wastewater treatment

Removes organic substances and toxic pollutants from industrial wastes through natural adsorption.

Air / Gas Treatment

Classification Description: This pure carbon surface is particularly effective at capturing gases and vapours, but little kinetic display is observed in Chemical activity so it could be labelled as inactive for chemical purposes. Very useful for sensitive air treatment applications, etc.

Air purifying

Activated carbon is extremely effective at removing VOCs (volatile organic compounds) and other smells from indoor air in domestic, commercial and health establishments.

Biogas

It can be used to purify biogas (which if untreated would contain hydrogen sulphide and other contaminants), enhancing gas quality for other uses.

Food & Beverage

Description：High-purity PAC is used as an active ingredient in pharmaceutical products and treatments for its detoxifying properties.

Chemical-Free Purchase Control: To create food-safe environments for this product, we used only those methods to activate it that are free of all chemicals.

Decoloration of Food - Only used physical adsorption techniques to remove the dye from food oils and sugars with no risk of contamination from chemicals.

Medical

Types of classification: This category of the chemical has no chemical activators, so it is appropriate for use in medical products that are being manufactured to high purity levels.

Medicating

The chemical is utilised in the production of pharmaceuticals to allow for chemical-free purification and provide the safety and compliance of these products when manufactured.
