## Abstract The cyclone sections of fluid coking reactors at oil sand upgrading facilities have been observed to undergo severe coke fouling during each operational cycle. This work was conducted to determine if vapour phase deposition mechanisms could be responsible for the formations observed in
Ar. analysis of the fluorescence of 3,4-benzpyrene in the vapour phase shows two contributions to the. "anomalous" fluorescence: (i) the emission from the second excited state to the ground state and (ii) a vibronically induced S1 -. So emission originating from the +520 cm -' vibrational level. A c
