Highlights  Solid hydrocarbons (C20-C42) are representative of soluble organic fraction of Diesel soots  Oxidation of these hydrocarbons mixed with a Pt catalyst is dependent on their volatility  Their molecular structure (number of cycles, H/C ratio,…) influences oxidability and volatility in a similar manner  There is a good correlation between light-off (oxidation) and boiling temperatures (volatility).  Optimal oxidation process occurs when there is a good fit between these temperatures. *Highlights (for review)
