    Envirocarb 207C 4X8 AND 6X12: Coconut Based Granular Activated Carbons

    Uploaded by

    Alfonso Blanco
    This document provides information on Envirocarb 207C granular activated carbons for general air treatment applications. It describes the products as high activity carbons manufactured from coconut shells to produce a selected pore structure and excellent filling characteristics. Typical properties include a bed density of 510 kg/m3, hardness of 97%, and total surface area of 1100 m2/g. It also discusses recycling the carbons by thermal reactivation.
