Abstract:
The EPA is considering further reductions in particulate matter (PM) emissions from gasoline combustion. Techniques to understand, manage, and mitigate PM are being undertaken by the fuel industry to prevent over-restrictive backend distillation regulations, which could reduce available fuel volumes. This presentation will discuss the particulate matter index (PMI) as a tool to estimate PM emissions from gasoline composition, provide an overview of industry efforts to improve and standardized compositional analysis, and finally share a comparison between traditional detailed hydrocarbon analysis (DHA) and the gas chromatography/vacuum ultraviolet (VUV) detection technique. VUV spectroscopy is versatile and well-suited to aromatic and diaromatic analysis – the compounds that contribute the most to particulates. Importantly, the technique is less laborious and more suited for a production environment than traditional DHA.
