abstract = {The development of more efficient clean up techniques in
coal power plants is essential in order to reduce trace
metals emissions into the atmosphere. However, understanding
of the behavior of the trace metals during the gasification
process is necessary for the optimization of the hot gas
cleaning systems. Thereby, in this work the influence of
H2O, HCl, and H2S on the release and condensation behavior
of Cd was experimentally investigated. The experiments were
conducted in two different setups. The condensation behavior
(temperature and speciation) of the trace metal vapors was
investigated in a heated flow channel reactor housed in a
furnace with a gas cooling zone. Experiments on the release
of the inorganic vapors were carried out in a heated flow
channel reactor coupled to a molecular beam mass
spectrometer (MBMS) in order to analyze the gas in situ. The
results of the experimental investigations were compared
with Scheil–Gulliver cooling calculations performed by
FactSage 6.3. Furthermore, thermodynamic pseudoequilibrium
calculations were carried out to help in understanding the
condensation mechanisms of the trace metal cadmium and the
global kinetics in the experiments. The experimental results
showed that the main chemical species detected in the
condensation and release experiments were Cd, CdO, CdCl2,
and CdS. In general, the speciation as well as the
temperatures at which the species condensed and were present
in the gas phase in the release experiments had the same
trend in the calculations and in the experimental results.
Thus, the Scheil–Gulliver cooling model was proved to be
an excellent tool for the prediction of the release and
condensation of cadmium. With this work, a better
comprehension of the behavior of cadmium under gasification
conditions was obtained.},
