Characterization of silicon species issued from PDMS degradation under thermal cracking of hydrocarbons: Part 1 - Gas samples analysis by gas chromatography-time of flight mass spectrometry

- The understanding of antifoaming degradation is essential for silicon speciation.
- PDMS degradation under thermal cracking of hydrocarbons was achieved.
- Volatile siloxanes, silanes and silanol were characterized by GC/TOFMS.
- A breakthrough in silicon speciation to understand silicon poisoning in gas cuts.
