Coking properties of coal pitch in coal batch

Coking properties of coal pitch in coal batch The coking properties of coal pitch depend significantly on its fractional composition, which determines the set of structural components involved in meso-phase formation. The optimal combination of high-molecular aromatic compounds, polycyclic compounds of intermediate molecular mass, and hydrogen-donor hydroaromatic components corresponds to a ratio of pitch fractions α: β: γ = 1: 2: 2. This is typical of coal pitch with a softening temperature of 75–85°C. Such pitch is the best clinkering additive to coking batch, resulting in the production of coke of maximum strength. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

The coking properties of coal pitch depend significantly on its fractional composition, which determines the set of structural components involved in meso-phase formation. The optimal combination of high-molecular aromatic compounds, polycyclic compounds of intermediate molecular mass, and hydrogen-donor hydroaromatic components corresponds to a ratio of pitch fractions α: β: γ = 1: 2: 2. This is typical of coal pitch with a softening temperature of 75–85°C. Such pitch is the best clinkering additive to coking batch, resulting in the production of coke of maximum strength.
