Distinguishing Coal, Coke and Other Black Particles

2018-3-1  This paper focuses on two types of black particles: coal and petroleum coke. Coal is a term for a brown and black, brittle, com-pact, amorphous combustible sedimentary rock con-taining more than 50% by weight and more than 70% by volume carbonaceous material (3). All types of coal are formed naturally by the application of heat and

Carbonaceous Materials - an overview ScienceDirect Topics

Carbonaceous material is a ubiquitous component of atmospheric aerosols. From combustion processes, carbon-containing compounds are emitted directly into the atmosphere in particulate form, a prime example of which is soot. In addition, during the gas-phase atmospheric oxidation of organic gases (by species such as OH, O3, and NO 3), products ...
