- Abstract:
- Using municipal sludge as raw material, a new type of magnetic sludge activated carbon was prepared through zinc chloride activation-tube furnace pyrolysis, activated carbon/iron oxide co-precipitation and bonding extrusion molding, and through orthogonal experiments and BET, SEM, IR and magnetic intensity measurement were used to systematically study the preparation process of activated carbon, the microscopic morphology and properties of the products in each step. The results showed that: when the zinc chloride activator concentration was 3 mol/L, the pyrolysis temperature was 650 °C, Under the preparation conditions of pyrolysis time of 2 hours and liquid-solid ratio of 2:1, the iodine value of the obtained sludge activated carbon reached 334.6 mg/g, and the specific surface area of activated carbon, magnetized activated carbon, and shaped magnetized activated carbon were all ≥300 m2/g. It can be easily separated by a magnet, and it is expected to have a good practical application prospect.
