不同粘结剂对炭膜孔结构性能的影响

he coal residue obtained from Jiahe gas coal of Xuzhou, as raw material, with the KOH as activator, was prepared into carbon membrane. The effects of sodium humate, asphalt and starch as binders on carbon membrane porosity and permeability were investigated, meanwhile, the suitable binder was selected out. The results showed that: starch, as a better binder, when the added amount of which was 5%, the best carbon film was prepared. And the carbon film surface was more complete, smooth, no needle and good plasticity, with the porosity and permeability, respectively 44.48％ and 5685 L / (m2 o h o MPa), developed pore structure, and pore size distribution concentrated in 3 ~ 15 nm.
