Production Of Biodiesel From Waste Cooking Oil Using
Sulfated Tin Oxide Catalyst.
Masters thesis, Universiti Sains Malaysia.
Abstract
Biodiesel is a renewable, biodegradable and non-toxic fuel which can be easily produced through transesterification reaction. However, current commercial usage of refined vegetable oils for biodiesel production is impractical and
uneconomical due to high feedstock cost and priority as food resources. Low-grade oil, typically waste cooking oil can be a better alternative; however, the high free
fatty acids (FFA) content in waste cooking oil does not allow efficient production of biodiesel via current commercial homogeneous transesterification process. Therefore,
in the present study, superacid sulfated tin oxide catalyst, SO4
2-/SnO2 has been
prepared using impregnation method for biodiesel production via heterogeneous
transesterification process.
