The article „SO2 disproportionation for a sulphur-based thermochemical cycle studied in an operando Raman batch reactor” has been published in the journal Physical Chemistry Chemical Physics (PCCP).
As part of the Sulphurreal project, a team at the Department of Chemical Engineering at the University of Patras investigated the iodide-catalysed SO2 disproportionation reaction at a temperature of 118 degrees Celsius and total pressures up to 9 bar. The disproportionation of SO2 is one of the three process steps constituting a solar-aided thermochemical sulphur-based cycle for producing unlimitedly storable sulphur that can be used on demand.
Use of Raman spectroscopy to study the iodide-catalysed SO₂ disproportionation reaction
The research team used in situ and operando Raman spectroscopy – which are advanced analytical techniques used to study how materials change in real-time under operating conditions. Raman spectroscopy allows for the identification and characterisation of materials by analysing their vibrational modes.
The results offer insight into the mechanism of the homogeneous iodide-catalysed SO2 disproportionation at the molecular level and are discussed in terms of their implications for its technical integration into the sulphur-based solar-aided thermochemical cycle.
