SAP Saturates, Aromatics and Polars

Some examples of SPE results are shown in Table 2. The DECSE3 diesel is a sample from another study diat was used to investigate the effeets of sulfur levels on the operation of diesel exhaust emission control devices, and the remaining samples were obtained from various refineries across Canada. These fuels were prepared for a collaborative research program Canadian Diesel Fuel Composition and Emissions .  

The results point to a very good agreement between LC (ASTM D2549 and ASTM D2007M - NCUT), SFC (Syncrude Research, Edmonton), and modified SPE results for all the tested fuels.
