Production method of meso-carbon microbeads

摘要

It is intended to provide a method of narrow particle size distribution, surface is produced with good yield a smooth meso-carbon microbeads are spherical. Carbonaceous component (1), a mixture of carbonaceous component less aromatic than (1) and (2) the carbonaceous component, for _a1 aromatic carbon fraction f of the carbonaceous component (1) producing meso-carbon microbeads by heat-treating a mixture of a2 _{/ f a1 a2} ratio _f of aromatic carbon fraction _f carbonaceous component (2) is 0.95 or less. The carbonaceous component (1), it may be composed of one kind selected from the coal tar pitch and coal tar. Also, for example, the carbonaceous component (2) may be constituted by a pitch as a raw material ethylene bottom oil, decant oil, asphaltenes, and they. For example, the former / the latter ratio carbonaceous component (1) the carbonaceous component (2) may be (by weight) = 99/1 to 30/70.
