In an activated carbon packed column,an experiment on desulphurization by liquid phase catalytic oxidation with FeSO_4 was carried out and the effects of liquid-gas ratio,superficial gas flow rate,ab.

Effect of active filler on joining property of silicon carbide to itself by polysilazane;

The design,cross-linking and pyrolysis of preceramic polymers as well as addition of active filler,all of which influence the ceramic yield,were analyzed.

Al and SiC powders were chosen as active filler and inert filler,respectively,for the fab- rication of preceramic-derived multi-phased ceramics,using polycarbosilane as preceramic precursor.

The advances in research on modified activated carbon materials in surface structure and physico-chemical properties are reviewed.

This text summarizes the research situation of FGD by the activated carbon materials (concentration on studying at present: oxygen functional groups; nitrogen functional groups;metal and metal compound on the surface of activated carbon materials).

By adding pore forming agents,which evaporate during carbonization and leave behind pores in the carbon matrix, into the parent polymer ,pore size distribution in activated carbon can be controlled.
