In order to study the effect of petroleum pitch(PP) as a coal tar pitch additive on the structure and electrical conductivity of pitch coke,the refined coal tar pitch(RCTP) was mixed with PP and cocarbonization.,and t The coke was prepared with the help ofunder mechanical agitation.Meanwhile At the same time,the influence mechanism of PP and mechanical action in the process of co-carbonization was elaborateddiscussed and analyzed.The structure of the semi-coke was analyzed by polarizing microscope,X-ray dif...
