tars

The physical and chemical synergism exists in the co-carbonization of plastics and coal and reduces the chance of secondary reaction, which increases tar yield and favours the formation of methyl-substituted aromatic compounds in tars.

塑料与煤共焦化过程中同时存在物理和化学协同作用，减少了二次反应的机会，增加了焦油收率，同时促进了焦油中芳香化合物的甲基化。
