Understanding emission dynamics in bitumen using HSGC-MS: an exploratory study of additive interactions

This study employs headspace gas chromatography mass spectrometry (HS-GC-MS) to investigate the influence of additives on volatile organic compound (VOC) emissions in bitumen. The research examines the interplay between the analysed chemicals and additives and considers the effects this may have within bitumen matrices. Considering the principles of partition coefficient (PC) and emission pattern observations, the method sheds light on the nuanced dynamics of additive interactions. The effects of powdered activated carbon, synthetic zeolite 13X, and Re-refined engine oil bottoms (REOB) additives on emissions are explored, revealing their impacts. HS-GC-MS offers direct VOC analysis in the gas phase, eliminating complex extraction techniques and filtering. The findings stress the importance of considering additive consequences in bitumen emissions. The methodology enhances additive selection for sustainable materials and broadens emissions comprehension. HS-GC-MS is a crucial tool for refining additives and addressing diverse application implications of additives. This work underscores the need to utilise varied approaches for bitumen and additive interactions.
