Web26 dec. 2024 · The hydrogen (H2) aromaticity of coal tar pitch (ratio of aromatic to total content of H2 atoms) varies from 0.7 to 0.9. Production of coal tar pitch Coal tar pitch is currently produced from coal tar, which is a byproduct of high temperature coking of coal in the manufacture of metallurgical coke. WebThe melting and decomposition temperatures increase by the addition of PF and PET. The melting point slightly increases only by 2.6–6.4°C while the decomposition temperature markedly increases from 307.6°C of the pitch itself to 367.1°C by PF adding and 387.0°C by PET adding.
