Introduction to Activated Carbon Activated carbon (sometimes called as activated charcoal) is a processed carbon-based material to maximize its adsorptive properties, yielding a superior adsorbent material. Physical and chemical properties of activated carbon varies significantly depending on the source material, and the processing methods used. There are three main types of activated carbon produced: powdered, granular and pelletized or extruded. Activated carbon is generally produced through a two stage process: carbonization and activation. During carbonization the raw material is thermally treated (pyrolysis) in inert environment to remove oxygen, hydrogen, nitrogen, sulfur etc. from the source material. During activation, carbonized materials is oxidized, or treated with oxygen, either by exposure to CO2or steam (physical) or by an acid-base chemical treatment. While selecting an activated carbon for a particular application, variety of characteristics are considered like pore structure, hardness/abrasion, adsorptive properties, apparent density, ash content, pH value, and particle size. The ability to adsorb components from a liquid or gas makes activated carbon useful in water purification, air purification, recovery of precious metals such as gold and silver, electrodes in super capacitors, and such other myriad of applications. 3 For sources of information, please refer to Appendix 1
Growth Prospects The global activated carbon market size was estimated at USD 4.72 billion in 2018 and is expected to expand at a CAGR of 17.5% during the period 2019-2025 with increasing demand in super capacitors, water treatment, and sewage treatment applications to be key growth drivers. Activated carbon is extensively used in water and sewage treatment owing to its ability to remove particulate and dissolved impurities. It also eliminates certain organic impurities and removes chlorine from water. The United States Environmental Protection Agency (EPA) and government regulatory agencies have recommended activated carbon as the best available material for removing chemical impurities such as mercury. It is a critical time to understand the global competitive environment of activated carbon from a patent perspective, and in-depth patent analysis of key technologies & players can help anticipate changes, detect business opportunities, mitigate risks, and make strategic decisions to strengthen one s market position and maximize return on one s IP portfolio. Some of the prominent participants in the global market of activated carbon are Cabot Corporation, Jacobi Carbons AB, Calgon Carbon Corp., Osaka Gas Chemical Co. Ltd., and Evoqua Water Technologies LLC. 4 For sources of information, please refer to Appendix 1
