aromatic hydrocarbon

[¦ar·ə¦mad·ik ¦hī·drə′kär·bən]
(organic chemistry)
A member of the class of hydrocarbons, of which benzene is the first member, consisting of assemblages of cyclic conjugated carbon atoms and characterized by large resonance energies. Also known as arene.

The generated polymeric forms of phosphoric acid further lead to conglutination among the produced loose "graphite worms," and enhancing continuous, compact of residue layers, suppressing "popcorn effect." At the same time, phosphoric acid, produced in APP decomposition, shows a catalytic action for RPUF depolycondensation reaction, which leads to the formation of a phosphor-carbonaceous polyaromatic structure.

This analysis includes the mass balance of trace metals in the initial fuel and the formed ash, the emissions of dioxins/furans (PCDD/F), polychlorinated biphenyls (PCB), polyaromatic hydrocarbons (PAH) and particulate matter (PM 2.5-10), and conventional air emissions, such as N[O.sub.x], S[O.sub.2], C[O.sub.2], CO, HCl, and total suspended particles (TSP).
"This reduction in DPM size is of particular concern as larger DPM (less than 2.5 [micro]m) coated with polyaromatic hydrocarbons (PAH, a known carcinogen) will affect a minority of the population, whereas the smaller (less than 100 nanometer) DPM can cross the lung membrane barrier into the bloodstream.
