In this paper, sintered active carbon (SAC) was prepared by sintering cocoanut powdered activated carbon at certain temperature and high pressure using polyethylene as macromolecule binder. The effects of material ratio, time and sintered temperature on density, intensity and micro-structure of SAC were investigated. The ratio of PE to AC showed the greatest influence on the mechanical properties and adsorption properties of SAC. As the increase of the amount of active carbon, specific surface area of SAC increased rapidly, but the intensity decreased. The processing parameters were optimized by the single factor test as follows: AC：PE 3:1, 200 ℃, 15 MPa and 30 min. Analysis of MB and N2 adsorption property of SAC and AC showed that, there was no significant difference between the two materialsd. As a new binder for SAC, PE can improve the mechanical properties of SAC greatly, but decrease the surface area. The SAC samples were all have excellent mechanical properties.
