Changing the Properties of Coal Pitch by Means of Additives

Аннотация

The influence of various additives—including nanoparticles—on coal pitch is investigated, with a view to improving its properties. Surfactants facilitate the formation of coal-pitch products but have little effect on their properties. Materials that react with the pitch components may increase the yield and microstructure of pitch coke. Nanoparticles increase the yield of pitch coke and its aggregate strength. Additives are classified in terms of their effects on the pitch.
