Abstract
Effects on Sustainable Aviation Fuel (SAF) addition to traditional Jet fuel (Jet A1) on particle number emissions over 10 nm have been evaluated with a small gas turbine engine which maximum output is 210 N. The tested engine was small compared with a gas turbine engine used for aircraft, however the NOx and particle number emissions factor of the tested engine were almost the same level with those of actual aircraft jet engines.

As for SAF, Hydrotreated Esters and Fatty Acids (FEFA) and Catalytic Hydrothermolysis Jet (CHJ) were tested. HEFA consists mainly of parafine and no aromatics are contained. On the other hands, CHJ contains aromatics over 20 %.

This research was performed by the Environment Research and Technology Development Fund (JMEERF20245005) of the Environmental Restoration and Conservation Agency provided by Ministry of the Environment of Japan.
