3-2-1 Emission-less production of biodiesel by organic-inorganic hybrid catalyst

Abstract

To improve productivity of biodiesel fuel (BDF), preparation of the noble catalyst that consists of magnetite and mesoporous silica bearing organic base has been studying for our research work. The magnetism makes it easy to reuse the catalyst for the transesterification to produce biodiesel, and mesoporous silica is crystallized over magnetite in the expectation that a large amount of silanol group brings about an increase in the bearing site. Primarily, mesoporous silica bearing organic base was prepared as the model catalyst for verifying the expectation about the increased catalyze activity. Also, the preliminarily coat of amorphous silica to magnetite was tested, for protecting it from the acidic condition to crystalize mesoporous silica.
