Transesterification of waste cooking oil to biodiesel fuel using K3PO4 catalyst |
| 초록 |
Biodiesel fuel (BDF) is a renewable alternative fuel and reduces the consumption of crude oil and the production of CO2 emissions. It has been generally obtained by transesterification of triglycerides in vegetable oils and animal fats with an excess of methanol in the presence of a homogeneous catalyst。 However, the use of a heterogeneous catalyst for BDF synthesis has many potential advantages: it is environmentally benign, noncorrosive to the reactor, creates no soap byproducts by reacting with free fatty acid (FFAs), and is easily separated from the reaction mixture.In this study, tri-potassium phosphate was used for the transesterification of waste cooking oil with methanol. It is found that tri-potassium phosphate shows high catalytic properties for the transesterification reaction, compared to CaO and tri-sodium phosphate. Transesterification of waste cooking oil required approximately two times more solid catalyst than transesterification of sunflower oil. The fatty acid methyl ester (FAME) yield reached 97.3% when the transesterification was performed with a catalyst concentration of 4 wt% at 60 oC for 120 min. |
