Using inexpensive and high-quality oil feedstock is an effective means to produce low-cost biodiesel. This
work investigated the production and fuel properties of biodiesel derived from Hodgsonia macrocarpa
(HM). The oil content of HM seed was 71.65 wt%, which is much higher than that of many potential
oil plants. With traditional base-catalyzed transesterification, biodiesel was readily prepared from HM
seed oil. The biodiesel yield was 95.46 wt% from HM seed oil. Biodiesel derived from HM met all ASTM
D6751 and EN 14214 specifications, except for oxidative stability (OS). The OS specifications of the
two biodiesel standards were met after treatment of HM biodiesel with 400 ppm tertbutyl hydroquinone.
The biodiesel exhibited excellent transportation safety and cold flow properties, with flash point of
153 C, pour point of 9 C, and cold filter plugging point of 7 C.
