- Abstract
- The presence of sulphur containing compounds,
naturally occurring in natural gas or added as
odorants, can adversely affect the performance of noble
metals based catalysts for the partial oxidation of methane
to syngas. In this paper the effect of SO2 addition on the
catalytic partial oxidation of methane was investigated on
Rh (1 wt.%) catalysts prepared by incipient wetness
impregnation method on two different commercially
available high temperature c-alumina supports stabilized
either with 10% SiO2 or 3% La2O3. Based on the results of
catalytic activity measurements and in-situ FT-IR spectroscopic
characterisation, as well as TPR/TPD studies, it
has been shown that the presence of sulphur can severely
suppress the formation of synthesis gas by inhibiting the
reforming reactions during the catalytic partial oxidation of
methane. The results also demonstrated that the support
plays a crucial role in the partial oxidation reaction. In the
presence of a sulphating support such as La2O3-Al2O3 the
partial oxidation reaction was much less inhibited than a
less sulphating support such as SiO2-Al2O3. The sulphating
support acts as a sulphur storage reservoir, which
minimises the poison from adsorbing on or near the active
Rh sites where reactions take place. (literal)
