Abstract:
     The preparation method of mesophase carbon microsphere includes the following steps: preparing raw material, polymerization reaction, product separation and drying, in which the composition of its raw material comprises (wt%) 80-99.9% of basic material which can be any one or both of asphalt and aromatic heavy oil and 0.1-20% of catalyst which can be any one or two kinds of nitrated compound of iron, nickel and cobalt. Said invention features high product yield, controllable grain size and uniform grain size distribution.
