THE STUDY ON TUBULAR POROUS CARBON MEMBRANE

The Preparation and application of tubular porous carbon membrane were studied. A support carbon membrane and a carbon carbon composite membrane prepared by different raw materials and the effects of main factors on pore structure of carbon membrane were investigated. Results indicated that the coal and phenolic resin are the good materials for preparing carbon membrane. The support carbon membane prepared not only has a higher porosity and gas permeability and flux, but also a higher mechanical strength and uniform pore structure. Factors such as types and particle size of raw material, and carbonization condition have an obvious effect on pore structure of carbon membrane. The pore size and distribution of the carbon carbon composite membrane become small and narrow after coating phenolic resin and coal pyrolytical product on support carbon membrane. The separation results of carbon membrane on filtrating beer and waste water are very remarkable.
