ACTIVATION. Activation occurs at temperatures between 1,750º F and 1,850º F, with the required temperature profile and retention time depending on the starting material and the desired quality of the end product. At 1,750º F, steam is injected into the system to remove any remaining volatile components, yielding activated carbon.
