abstract = {In order to achieve an environmentally friendly treatment
of growing municipal solid waste, gasification technology as
a good candidate gains increasing attention and will play a
vital role in the processes of waste-to-energy. In this
study, the condensation behavior of trace metals Pb and Cd,
especially in HCl/H2S containing gas mixtures was
investigated under lab-scale gasification conditions. It was
found that PbO was a completely predominant condensation
species in atmospheres containing H2O or HCl while regarding
Cd condensation under identical conditions metallic Cd
prevails. It was also observed that the presence of 125 ppmv
HCl caused a significant shift of the condensation of PbO
from 790 to 670 °C. In the presence of H2S, the
condensation as sulfides, i.e. PbS and CdS occurred
overwhelmingly. A mechanism for the condensation of PbS was
proposed, with which an interesting phenomenon was
illuminated that the condensation of PbS moves to higher
temperatures as the H2S concentration increases from 125 to
250 ppmv, while it shifts towards lower temperatures with a
further concentration increase to 500 ppmv. In addition, the
difference in condensation mechanism for Cd and Pb was
compared and discussed.},
