Preparation of porous membranes with the residues obtained by the eztraction of coal

摘要：

The porous membranes with different percentage of carbon were prepared with the residues obtained by the extraction of coal. The results showed that carbonization conditions greatly affect on the properties of porous membranes. The activation of the membrane with water vapor made a significant increase in the porosity. The obtained porous membrane has small average pore size and narrow pore size distribution, and high porosity. Experimental results showed that the coal residues can become a better porous membrane precursor.
