Influence on constitutes and properties of coal tar and pitch by heat carriers temperatures, constant temperatures and volume of heat carriers vs pulverized coal was studied, when Xinjiang coal was pyrolysised by heat carriers. The test showed that: main constituents of tar were BTEXs and phenol compounds, less PAH. There are three phases on TG-DTG curve of coal tar pitch. heat carriers temperatures have less impact on coal tar pitch prolysis, volume of heat carriers vs pulverized coal have comparativelylarge impact on coal tar pitch prolysis, constant temperatures have evident influence on coal tar pitch prolysis only when temperatures under 500℃.
