In the previous study combustion characteristics were mainly investigated based on engine tests and, as a result, FCC oils were found to be the most problematical not only in wear but also in combustion.
In this study it was tried to establish some methods to identify FCC oils. The main results obtained are (1) the molecular weight charts of GPC can clearly identify FCC oils (2) evaporation diagrams of TGA are, however, unable to identify them and (3) “particle gauge” is recommendable as an instrument on board because the gauge enables it not only to detect FCC catalyst fines but also to make broad estimation of their content in a simple practice.
