On the pitch cokes of different origins baked upto a defined temperature, quantity of bromine captured by them were determined and discussed.
The least capture quantity of bromine always appeared in the pitch cokes treated upto 1600°C on all sort of them. The fact indicate that essential carbon crystal arrangement begin from this point. As baking temperature approacing upto nearly 2000°C, bromine capture quickly increased. It shows increase of bromine graphite formation depend on growth of the net plane of graphite lattice.
Carbons of fine crystallites, as soot, lesser bromine graphite formation even if baking upto a sufficient high temperature. Amount of bromine capture by carbons somewhat decrease over some sufficient high temperarure baking. The fact probably due to loss of activity by improvement of crystallite arrangements.
