Step 4 : Pyrolysis and Activation
The word pyrolysis originates from the Greek-derived elements pyro “fire” and lysis “separating”.
Pyrolysis is a conversion technology involving the thermal decomposition of organic matter at atmospheric pressure with temperatures ranging from 300˚C to 600˚C in the absence of oxygen within a heat transfer reactor. At NewCarbon we follow an innovative continuous production process.
Bio-carbon is physically activated by introducing oxygen and/or flue gas at temperatures above 700˚ C. Activation produces Powdered Activated Carbon (PAC) and Granular Activated Carbon (GAC) that cannot be produced under standard pyrolysis conditions. Applications are in niche markets such as water purification, the food, beverage, and pharmaceutical industries, and animal feed. It is of high value because of the complexity of the production process and level of product engineering required.
