RATE CONSTANTS OF ELECTRON-BEAM PAHs DECOMPOSITIONGennady Gerasimov Institute of Mechanics, Moscow State University, 1 Michurinsky Ave., 119192 Moscow, Russia The generalized kinetic model of the electron-beam induced processes in industrial flue gases elaborated earlier is used for the estimation of rate constants of hydroxyl-radicals interaction with high-ringed aromatic compounds. These data are received by means of the fit of the calculated PAHs concentrations to the measured ones as applied to benzo(a)anthracene, benzo(e)pyrene, benzo(a)pyrene, perylene, and dibenzo(a,h)anthracene. It is shown that the concentrations of PAHs decrease by more than an order of magnitude at the absorbed dose D = 20 kGy for compounds with rate constant of their interaction with OH-radical more than 1013 cm3 mol-1 s-1.
