Silicon speciation has recently gained interest in the oil and gas industry due to the impact of silicon species on hydrotreatment (HDT) catalysts. The determination of the chemical structure of silicon compounds appears as essential to limit silicon poisoning as to improve the lifetime of catalysts. To achieve a representative speciation of silicon in petroleum products, fresh samples of PDMS degradation...
A method for the speciation of silicon compounds in petroleum products was developed using gas chromatography coupled to mass spectrometry (GC–MS). Prior to analysis, several precautions about storage and conservation were applied for all samples. In spiked gasoline samples, limits of detection between 24 and 69μgkg −1 for cyclic siloxanes (D 4 –D 6 ) and between 1 and 7μgkg...
