The viscsity f idine treated pitch shwed that the fluidity f idine treated CTP did nt increase within the idine additin f 1.4%. DTG analysis shwed that crss linking was accelerated at the temperature range frm 400 t 500 C with idine treatment, which is due t the accelerated dehydrgenative reactin by idine. The idine treatment was mainly effective fr β-resin cntent increase f CTP. The carbn yield f CTP increased frm 40 t 60% by the idine nn-treated CTP.
