Process Technologies
High surface area activation
Technology
Innovative in-house capabilities to manufacture coconut shell activated carbon products with surface areas of 1600 m²/g, 2000 m²/g, and 2500 m²/g with selection of precise preparation of raw materials and activation technology
High Purity acid washing
Technology
Our in-house technical innovations include advanced washing technologies designed to obtain ultra-pure products required for Energy Storage Applications. This innovative process removes impurities to less than 500 ppm levels.
Surface modification
Technology
Our innovative technologies are designed to modify the surface functional groups and surface chemistry of the carbon as applicable to supercapacitor and Si-C composite carbon. In addition, there are some other types of special surface modifications which can be incorporated to create catalytic activity, hydrophobic and hydrophilic properties to the surface chemistry. This enables selective adsorption of target contaminants.
Impregnation Technology
Impregnated activated carbon undergoes a unique chemical treatment to develop specific properties. This treatment methodology include changing the surface nature with of activated carbon and enhancing the affinity to various contaminants in air and liquids with catalytic activity by using different treatment conditions.
Precision sizing Technology
To ensure precision particle sizing of granular, fines, and powdered activated carbon, we utilize specialized processes that consistently achieve narrow size distributions as required in energy carbon applications. We have developed advanced processes to effectively remove micron or submicron particles.
Regeneration Technology
Haycarb Activated carbon regeneration is a cost-effective and environmentally friendly technology that restores used carbon to 97% of its original adsorption capacity, allowing multiple reuses. This process involves transporting spent carbon to a regeneration facility, where it undergoes thermal regeneration to eliminate contaminants, mimicking the initial manufacturing process. The regenerated carbon, supplemented with some virgin material to offset processes and handling losses, is then returned to the customer. Haycarb supports this with technical advice and onsite system installation, ensuring that regenerated carbon delivers performance on par with new material. This method is especially effective for high-volume, long-term applications like solvent recovery.
Green Charcoaling Technology
Eco-Friendly Charcoaling Pit construction is designed to produce coconut shell charcoal using green technology through the “Haritha Angara” program. We provide technical know-how and financing to our charcoal suppliers to help them transition to environmentally friendly charcoaling methods. In addition to this, our in-house patented technology ‘RECOGEN’ produces coconut shell charcoal in a closed system enabling the combustion of harmful gases released during the production process. The heat generated in this process is used to operate a boiler/steam turbine to generate electricity which is supplied to the National Grid.
