On-Line Instrumentation for the Real-Time Monitoring of Polynuclear Aromatic Hydrocarbons in the Effluents from a Fluidized Bed Combustor - a Feasibility Study

摘要

When polynuclear aromatic hydrocargons in the vapor phase are diluted preferably in a rare gas and undergo supersonic jet expansion, rotationally cooled molecules with absorption bandwidths of the order of 0.01 nm (FWHM) are obtained. Selective excitation with a tunable dye laser into such narrow absorption bands leads to the observation of highly specific luminescence spectra. Such an approach has been utilized for the on-line, real-time monitoring of polynuclear aromatic hydrocarbons in the effluents from a fluidized bed combustor. (ERA citation 09:038354)
